8 1 Introduction The FlexFrame for SAP Management Tool is the successor of the FlexFrame for SAP Planning Tool. It takes over all the functions of the former Planning Tool and moreover offers a variety of new functions as well as the potential to further basic extensions of the functionality in the future. Although its implementation compared with the predecessor is based on fundamentally different technologies (Java and XML versus Microsoft Excel). One aim was to give a familiar and as far as possible compatible look and feel for its users. The FlexFrame for SAP Management Tool works together with FlexFrame for SAP versions 4.2A, whereas the previous FlexFrame for SAP Planning Tool works together with all FlexFrame for SAP versions prior to 4.2A. This manual describes how to work with the FlexFrame Management Tool which enables the certified FlexFrame consultant to enter the necessary configuration data for a customer-specific FlexFrame environment on a Windows PC with Java SE 6 and newly also on other platforms, e.g. Linux. With this tool you can create an initial FlexFrame configuration file modify an existing FlexFrame configuration file (new!) open an LDAP connection to a server to get a current FlexFrame configuration to be used as initial configuration (new!) create/modify the network cabling plan After the data has been entered correctly, it is stored in an XML file on an approved external data medium (e.g. an USB stick) and later read in by the installation scripts during the installation of the FlexFrame Control Center. The required FlexFrame configuration is implemented automatically using this configuration data. The two Control Nodes (CN) of FlexFrame for SAP are also named as the FlexFrame Control Center (CC). In this documentation the notation Control Node (CN) is used as a synonym for Control Center (CC) and the other way round. Among other things, the configuration files contain information on the: Network switch configuration DHCP parameters Hosts User and group parameters Services FlexFrame pool and group definitions NAS storage configuration SAP services Network boot parameters Database systems LDAP parameters Network wiring plan Management Tool 1

12 2 Network Concept The network concept of FlexFrame is very essential. We will therefore first provide a brief explanation of this concept. If you are already familiar with it, please continue with chapter Working with the Management Tool on page 9. The network is the backbone of the FlexFrame solution. Communication between the various nodes is done exclusively over the IP network infrastructure. This is used both for communication between server(s) and client(s) and for delivering data from the NAS (Network Attached Storage) to the server. The IP network infrastructure is essential for every FlexFrame configuration. FlexFrame is designed with a dedicated network for connections between server and storage that is reserved for FlexFrame traffic only. Only one network segment, the Client VLAN (see section VLAN Segments on page 6), is routed outside the FlexFrame network to connect to the existing outside network. The FlexFrame internal physical network configuration is fully redundant to ensure high availability. Based on this physical network, a number of virtual network segments are configured. One virtual LAN (VLAN) is used for FlexFrame infrastructure management and is called the Control LAN. Three further VLANs, the Client LAN, the Server LAN and the Storage LAN, are added for each pool. A pool is a set of Application Nodes in a Flex- Frame environment plus a set of preconfigured SAP services that belong to the same customer. A pool is usually related to a client. By assigning separate VLANs to every pool these clients are well separated. This multi client capability of FlexFrame is an essential feature. 2.1 LAN Failover LAN failover describes the ability of the FlexFrame environment to use a logical network interface that consists of several physical network interface cards (NICs), which in turn use redundant network paths (cables and switches). When a network component (NIC, cable, switch, etc.) fails, the network management logic will switch-over to another network interface card and path. 2.2 LAN Trunking High demands on network throughput the network path to the NAS system may require a bandwidth of more than a single NIC. LAN Trunking (IEEE 802.1q) allows multiple paths to the network backbone to be combined. The method applied is able to work with the coexisting LAN failover solution described above. It is also required that the load balancing uses the round-robin method based on Ethernet packages. Management Tool 5

13 Network Concept VLAN Segments 2.3 VLAN Segments FlexFrame relies on a virtual network concept, providing higher availability as well as increased flexibility for the FlexFrame environment. This concept relies on VLAN technology that allows multiple virtual networks to be run across a single network wiring system. Additionally, in order to ensure high network availability, LAN bonding is used on every node. This includes a double switch and wiring infrastructure, to keep the whole environment working, even when a network switch, cable or NIC fails. Furthermore, the network segments are prioritized to ensure that important connections are preferred. Similar to former FlexFrame versions, typically four networks are used within one Flex- Frame system or within a single FlexFrame pool. FlexFrame uses virtual network segments. These virtual networks run through redundant NICs, using bonding on Linux and IPMP on Solaris. The figure below outlines the basic network segments of a typical FlexFrame environment with Linux-based Application Nodes. 6 Management Tool

14 Host Names Network Concept The following virtual network segments are mandatory for FlexFrame: Client LAN (one for each pool) This LAN provides dedicated user connectivity to the SAP instances. This segment also allows administrators to access the Control Center. Control LAN (one for all pools together) This LAN carries all administrative communication for Remote View Service Board (RSB), IPMI-, XSCF- and/or RPS-interfaces, NAS devices and switches. Server LAN (one for each pool) This LAN is used for SAP instances to communicate with each other and with the databases. Storage LAN (one for each pool) This LAN is dedicated to NFS communication for accessing the executables of SAP and the RDBMS, as well as the IO of the database content and SAP instances. The network bandwidth has to be at least one Gbit/sec for all components (except for the Control Lan) to handle intense data traffic. 2.4 Host Names The host names of the individual VLANs are derived from the general host names of the respective components (e.g. Application Nodes). With exeption of the Client LAN the host names are provided with a suffix to permit an individual addressing via a VLAN segment: Control LAN: Server LAN: Storage LAN: <general_host_name>-co <general_host_name>-se <general_host_name>-st In SAP environments host names are currently limited to 13 alpha numeric characters including the hyphen ( - ). The first character must be a letter. In the SAP environment host names are case-sensitive (see SAP Note No ). 2.5 Switches Network switching components play a very important role within FlexFrame. Therefore, only the following switches are tested and supported: Cisco Catalyst 3750g Cisco Catalyst 3750e (including 10GbE NICs) This switch family supports VLAN technology for a flexible configuration of the various network segments and QoS (Quality of Service) to prioritize traffic (e.g. higher priority for production systems over test systems etc.). The Cisco StackWise Technology is able to use cross-stack LAN trunking (this means the usage of ports of different switches within one stack). Management Tool 7

16 3 Working with the Management Tool 3.1 Starting the Management Tool The Management Tool is shipped on the ServiceCD in the directory /config. It consists of the Jar files MgmtTool.jar, MgmtToolLoader.jar, xercesimpl.jar, xml-apis.jar and an optional Patch.jar, which have to be copied into the same directory under Windows or Linux. You can start the Management Tool in the Windows Explorer doing a double click on MgmtTool.jar. You also can start the Management Tool on the command line interface in the following way: o Navigate to the directory which contains the MgmtTool.jar. o Type java jar MgmtTool.jar When using the Patch.jar file, you have to call MgmtToolLoader.jar instead of MgmtTool.jar. Only MgmtToolLoader.jar activates the patches in Patch.jar. SUN Java SE 6 is required. The screen of the Management Tool ist opened. For an explanation of the different areas see the following section. At the moment the Management Tool does not possess a recovery function! If you delete an object by mistake, you can repair it by adding it again or by reading in the configuration file again with the Open -> Configuration File function. In the latter case, all input that you made previously is lost (if you did not accomplish a backup in the meantime). 3.2 Exit the Management Tool You exit the Management Tool by selecting Exit in the function area. Management Tool 9

17 Working with the Management Tool Screen Layout of the Management Tool 3.3 Screen Layout of the Management Tool The screen of the Management Tool consists of three different areas, in which you can execute the configuration tasks. The following figure is a photomontage illustrating all areas. Depending on the individual procedure step, all areas are not always visible. 1. Menu bar Here you find administrative functions of the PlanningTool. 2. Object tree Here you find an abstract object tree that represents a FlexFrame installation. When you select an object in this area with a left mouse click you get a differentiated view on this object or on the subtree of this object in the view area (3). This means, the selected object in the object tree determines the content of the view area and the 10 Management Tool

18 Screen Layout of the Management Tool Working with the Management Tool deeper you are in the structure the differentiated is the display of the parameters. If you select a leaf object you will see in the view area only the properties of the selected object. Depending on the selected object you can open a context menu by doing a right mouse click on the object. Via context menus you can carry out object dependent actions. Each action carried out produces a new object-dependent subtree in this area. 3. View area Depending on the selected object in the object tree, a view is opened in this area. This view consists of a table, a property list or of both of them in terms of split panes. In this area the values of all fields highlighted in white in the table as well as the values of the fields in the property lists can be changed via a pull-down menu or by direct input (the latter must be confirm with CR). If applicable, there are buttons above a table for carrying out. Each action carried out produces a new object-dependent subtree in the object tree. View area of the FlexFrame object (the root of the object tree) When you select the FlexFrame object, you get information on the whole FlexFrame installation in the view area. To select this information, the view area of the Flex- Frame object contains an additional tab bar. Depending on the selected tab in this bar, you get a global view on the configuration objects. For defining a basic Flexframe configuration most of the settings can be done under these tabs. For users of the old Excel Management Tool the FlexFrame view with its tabbed panes will look familiar For defining details of a configuration, which are not visible or changeable in the view area, you have to select the corresponding object in the object tree and to set the properties right at the objects itself.

20 4 Brief Instruction for Creating a New FlexFrame Configuration The validation of the data input is done by using the Validate Configuration function (see section 5.6). This validation always is context sensitive which means that the input normally is not checked directly when edited. Therefore it is recommended to use the Validate Configuration function in between the data input to check the data and correct data mismatch not only at the end of the complete configuration. To create a new FlexFrame configuration please perform the following steps: 1. After starting the Management Tool (see section 3.1) choose the function File->New Configuration in the File menu (see section 5.1.1). A dialog box is opened in which you have to specify the parameters for the first pool of the new FlexFrame environment. The input fields of this dialog box contain default values, which you can adapt according to your needs. Having done this, the new configuration consists of one switch group, one pool with one group and one NAS storage. 2. Add switches to the switch group (see section 8.15). Optional activities at this point: You can add 2.1. other switch groups to the desired configuration (see section 8.16) other pools to the desired configuration (see section 8.12) other groups to the existing pool(s) (see section 8.11) pool-specific external connectivities (see section 8.7) other NAS storages (see section 8.10) control stations (see section 8.4) and/or data movers (see section 8.5) in case of NAS storages of the type NS-Type volumes to the NAS storage(s) (see section 8.18) mount points for the added volumes (see section 8.9) global connectivities either manually or automatically with optional additional Client LANs (see section 5.8) one or more blade server chassis (see section 8.3). Management Tool 13

21 Brief Instruction for Creating a New FlexFrame Configuration 3. Add Application Nodes (see section 8.2). Optional activity at this point: You can add SAP services (see section 8.14) and corresponding SAP instances (see section 8.13). 4. Fill in the form for the control center settings (see section 6.3). 5. Generate the hosts parts of the IP addresses (see section 5.9). 6. Generate the network wiring plan (see section 5.7). 7. Validate the configuration (see section 5.6). In case of errors you have to correct them and validate the configuration again. 8. Save the valid configuration (see section 5.3). if you want to use the configuration for later installation, the file name must be ff_config.xml. 9. You can print the settings of the configuration (see section 5.4). 14 Management Tool

22 5 Menu Functions 5.1 Creating a New Configuration A new configuration can be created in the following three ways New Configuration Function With this function you can create a new initial configuration from scratch. The following dialog box is displayed in which you have to specify the parameters for the first pool of the new FlexFrame environment. The input fields of this dialog box contain default values, which you can adapt according to your needs. Management Tool 15

23 Menu Functions Creating a New Configuration First Pool Name First Group Name The name of the first pool. The name must start with a letter and may only contain numbers, letters and -. The pool name becomes part of an automatically generated host name that may only be up to 13 characters long in an SAP environment. Therefore, we recommend that the pool name should be limited to three characters and written in lower case letters. The name of the first pool group. The name must start with a letter and may only contain numbers, letters, _ or Management Tool

24 Creating a New Configuration Menu Functions First Switch Group Name The name of the first switch group. The name must start with a letter and may only contain numbers, letters, _ or -. DNS Domain Name DNS Server Network (LANs) Netmask (LANs) VLAN ID (LANs) NAS System The DNS domain name for the first pool. The name has to be conform to RFC1035. This means, the domain parts have to be separated by a dot and must consist of alphanumerical characters and dashes. The parts may not begin with a number or a dash. IPv4 address of the DNS Domain Server for the first pool. The name has to be conform to RFC1035 (see above). No entry is required for this field. If this field is empty, fully qualified domain names outside of Flex- Frame cannot be resolved by neither the Control Nodes nor the Application Nodes. The relevant network in IPv4 format. In binary, the network address must contain a zero at the same position as the netmask of the individual LAN segments. The individual networks must be different from each other. The relevant netmask in IPv4 format. In the network section the netmask must consist of binary ones, and in the host section of binary zeros. You are recommended to use the same netmask for all network segments. The relevant VLAN ID. The VLAN ID is an integer between 2 and The VLAN IDs must be unique over all LAN segments. Pull down menu with valid NAS types, name of the NAS system and number of NICs (2-8). After you have competed your input or for the assumption of the default values, press the OK button. The structured object list for this configuration will be displayed. Management Tool 17

25 Menu Functions Creating a New Configuration Open LDAP Connection Function With this function you can create a new configuration by reading in an existing configuration from LDAP and saving it in an XML file. A configuration file created with the Management Tool contains data that is not stored in the LDAP of a FlexFrame installation. These missing data must be added after reading in a configuration from LDAP. Before adding the missing data, a validation of the current configuration will always show errors (see Validating a Configuration on page 23). Even when the missing data has been added and no validation errors are indicated anymore, you should be aware, that the data read from the LDAP might be erroneous due to unpropper handling before. Data obtained by reading from LDAP should always be carefully verified. The Management Tool can only verify consistency. It cannot detect changed IP addresses or similar modifications. The following dialog box is dispayed in which you can choose a properties file. To open an LDAP connection, click on the corresponding file and then click the Open button. The structured object list for this configuration will be displayed. 18 Management Tool

26 Creating a New Configuration Menu Functions By clicking the Edit LDAP Properties button the following dialog box is displayed and you can modify the properties of the selected file and save them (Save as). By pressing the Set LDAP Properties button the same dialog box is displayed with blank input fields. LDAP URL Base DN User DN Password Address of the server for LDAP access. The Base DN (Distinguished Name) is the root for the LDAP name space for this FlexFrame environment. This can be a subset of a higher LDAP hierarchy. This field may be empty if the DNS domain name is specified. If a DNS domain is set and no Base DN exists, it is formed from the DNS domain when the Control Nodes are installed. The entry is not checked for plausibility! User DN of the LDAP user. Password of the LDAP user. Management Tool 19

27 Menu Functions Modifying an Existing Configuration Open Configuration File Function With this function you can create a new configuration by modifying an existing configuration file and saving it under a new name. The following dialog box is displayed in which you can select a configuration (XML file). To open a configuration file, click on the corresponding XML file and then click the Open button. The structured object list for this configuration will be displayed. 5.2 Modifying an Existing Configuration To modify an existing configuration, use the Open Configuration File function, modify the parameters and save it under the same name. 20 Management Tool

28 Saving a Configuration Menu Functions 5.3 Saving a Configuration You save a configuration by selecting the Save function. The following dialog box is displayed in which you can save the new/modified configuration in an XML file. To save a new configuration, type <file_name>.xml in the File Name field and then click the Save button. To save a modified configuration, click on the corresponding XML file and then click the Save button. The configuration file should be copied under the name ff_config.xml to the root directory of a blank floppy disk or USB stick. This external medium will be used for the installation. Within the Management Tool the file name is arbitrary. For the installation the file name must be ff_config.xml. Management Tool 21

29 Menu Functions Printing a Configuration 5.4 Printing a Configuration You can print the current settings of the choosen configuration by selecting the Print function. The views of all tabs or the wiring plan are printed. 5.5 Editing a Configuration With the functions Add and Delete you can execute the same actions, which are offered as buttons in different views. For more information see chapter View Area on page Management Tool

30 Validating a Configuration Menu Functions 5.6 Validating a Configuration With the Validate Configuration function yon can check whether the current configuration is valid and may be used by the installation script. By clicking this function the following message box displays the check results. You can reduce the output by activating the Show only errors checkbox. The validation of the data input is done by using the Validate Configuration function. This validation always is context sensitive which means that the input normally is not checked directly when edited. Therefore it is recommended to use the Validate Configuration function in between the data input to check the data and correct data mismatch not only at the end of the complete configuration. 5.7 Generating a Network Wiring Plan Yon can generate a network wiring plan automatically or manually. The automatic generation is recommended because it is the most comfortable and safest method to generate a correct network wiring plan. After the network wiring plan is generated, it is displayed under the Wiring tab in the FlexFrame object view (see page 55). Management Tool 23

31 Menu Functions Generating a Network Wiring Plan Automatic Generation You generate a network wiring plan automatically with the Perform Wiring function. Before you generate a network wiring plan with the Perform Wiring function, you must delete an existing network wiring plan with the Clear Wiring function. Only if the existing wiring is manually preconfigured and supposed to remain, you may call Perform Wiring without first resetting it. All NICs will be connected automatically to the related switch ports. The icons of the connected NICs and switch ports are marked green in the object tree (for an example see the figure in the following section). If there is more than one switch group these switch groups will be connected to ports of an abstract core switch. The core switch is in the responsibility of the customer environment (see network Design and Configuration Guide) Manual Generation To modify a network wiring plan manually, navigate to the appropriate entry in the object tree and select a value from the pull-down menu (see the example below). If the switch port is already connected, its icon is marked green in the object tree. Before you generate a network wiring plan manually, it is recommended to delete an existing network wiring plan with the Clear Wiring function. 24 Management Tool

32 Generating Global Connectivity Menu Functions 5.8 Generating Global Connectivity With the Management Tool a pool-independent global connectivity can be planned. It leads to configuration of abstract external connectivity devices. For a pool-specific external connectivity see page 54. The global connectivity is responsible for the global network connections which connect the internal FlexFrame network with the outside world (e.g. corporate network). With the global connectivity switch ports are defined, to which external devices can be assigned. After the global connectivity is generated, it is displayed in the object tree (see page 39) and under the Wiring tab in the FlexFrame object view (see page 55) Automatic Generation You generate the global connectivity automatically with the Perform Wiring function. Before you generate the global connectivity with the Perform Wiring function, you must delete an existing connectivity with the Clear Client LAN Connectivity function. With the automatic generation a standard wiring will be generated analogous to the following settings in the Network object (see also page 33): Client LANs on SWG ports = true One Client VLAN per SWP = false One common connection with two NICs for all existing pools Client LANs on SWG ports = true One Client VLAN per SWP = true One separate connection with two NICs for each existing pool If only one NIC is desired, you must delete it in the object tree. If the redundancy has to be used on the device side too, a similar active-backup failover configuration like on the Control and Application Nodes has to be used. The NICs will be connected automatically to the related switch ports. The icons of the connected NICs and switch ports are marked green in the object tree. Management Tool 25

33 Menu Functions Generating Global Connectivity Manual Generation To generate the global connectivity manually, perform the following steps: 1. If the entry Global Connectivity is not available in the object tree, create it: 2. Add a Client LAN Connection entry: 3. Under ClLanCons add (at least) one Client LAN entry: A dialog box is opened, in which you must link the Client LAN to the desired pool. If the desired pool does not exist yet, you can link the Client LAN later after you have created the pool: 26 Management Tool

34 Generating Host Parts of IP Addresses Menu Functions 4. To connect the NICs to the related switch ports, execute the Perform Wiring function (without executing Clear Client LAN Connectivity before), or set the connection manually (see below): 5.9 Generating Host Parts of IP Addresses Yon can generate the host part of the IP addresses of the Client LAN, Server LAN and Storage LAN automatically or manually. The automatic generation is a comfortable and safe method to generate IP addresses. The addresses must be unique within a Flex- Frame environment. An IPv4 address consists of a network section and a host section. In the network section the netmask consists of binary ones and in the host section of binary zeros. Example (the host part of the IP address is underlined): Netmask: > Host IP: Netmask: > Host IP: Generate Host Parts Automatically To generate the host parts automatically, first you have to reset them to a default value with the Reset All function. Then you can generate them with the Set All function Generate Host Parts Manually You can generate the host parts manually in the view area, by entering the values into the white highlighted fields of the corresponding columns or when setting the host property of a selected IP interface object.

36 6 Object Tree The object tree is an abstraction of the FlexFrame reality. 6.1 General Features Depending on the selected object in the object tree you get a differentiated view on this object or on the subtree of this object in the view area. This means, the selected object determines the content of the view area and the more deeply you are in the structure the more differentiated is the display of the parameters. You can modify certain settings of any object. By selecting an object, the releated view with the responsible input fields is displayed. Depending on an object you can open a context menu by doing a right mouse click on the object. Via context menus you can carry out object dependent actions. Each action carried out produces a new object-dependent subtree in this area. On page 57 you find an overview of all actions. With the Delete action you can delete all objects in the object tree. This action is carried out directly, no safety inquiry take place! If you delete an object by mistake, you can repair it by adding it again in the object immediately above or by reading in the configuration file again with the Open -> Configuration File function. In the latter case, all input that you made previously is lost (if you did not accomplish a backup in the meantime). The object tree consits of the major object FlexFrame and six basic objects described in the following. Management Tool 29

37 Object Tree FlexFrame Object 6.2 FlexFrame Object If you select the FlexFrame object, the tab bar is displayed which is emulated from the old Excel based Management Tool. Depending on the selected tab in this bar, you get a global view on the configuration objects in the view area (see page 41). 30 Management Tool

38 Control Center Object Object Tree 6.3 Control Center Object The Control Center consists of two clustered servers (Control Nodes) whose task is to monitor and manage FlexFrame (e.g.: Storage, ANs, SIDs), i.e. to supply them with information on the boot procedure, directory services (LDAP for hosts, services, etc.) and more (FA Control Agents). The figure on the left side shows the Control Center object as an example. By selecting this object, the Control Node part of the Controlling view is displayed (see page 44). The upper split pane shows a list of properties necessary for the Control Center (see Miscellaneous Control Center settings below). The lower split pane shows a table where more properties of the Control Center are shown in a similar way as properties of NAS systems or Application Nodes. If a NIC is already connected to a switch port, the icon of the NIC is marked green. The relation then also appears in the wiring view. Miscellaneous Control Center Settings Cluster Name Cluster IP1 / IP2 Name of the PRIMECLUSTER on the Control Nodes (default FlexFrame). First and second cluster IP address (both should be in the same network section). The cluster IP addresses IP1 and IP2 must be in separate host sections. At least four addresses are required: two IP addresses, a broadcast address and a network base address. Subnetworks are permitted. Example: Cluster Netmask: # Subnetwork with 4 addresses Network Base Address: Cluster IP1: Cluster IP2: Cluster Broadcast: Management Tool 31

39 Object Tree Control Center Object Cluster Netmask Netmask of the cluster (defines the cluster s network part). Control Node DNS Domain DNS domain name of the Control Nodes. The name has to exist already in the customer s network (e.g. myflexframe.fujitsu-siemens.com). The DNS domain name is required and has to be conform to RFC1035. This means, the domain parts have to be separated by a dot and have to consist of alphanumerical characters and dashes. Domain parts may not begin with a number or a dash. DNS Servers IPv4 addresses for DNS Domain Server (separated by blanks). No entry is required for this field. If this field is empty, fully qualified domain names outside of FlexFrame cannot be resolved by neither the Control Nodes nor the Application Nodes. LDAP Base DN The LDAP Base Distinguished Name is the root for the LDAP name space for this FlexFrame environment (e.g. DC=myFlexFrame,DC=fujitsusiemens,DC=com). This can be a subset of a higher LDAP hierarchy. This field may be empty if the DNS Domain Name is specified. If a DNS Domain is set and no LDAP Base DN exists, it is formed from the DNS Domain when the Control Nodes are installed. NTP Time Servers One or more Network Time Protocol Servers (IPv4 addresses separated by blanks). No entry is required in this field. If this field is left empty, the first Control Node becomes the NTP master server and the second Control Node will be a backup NTP server. Time Zone Time zone of the FlexFrame environment to be installed. Default Router Default router for the Control Nodes (IPv4 address). This router does not apply for the Application Nodes. The router must be in one of the Client, Server or Storage LAN segments. No entry is required in this field. LDAP Root User Root user (default: root). LDAP Root Password Root password (default: password). SNMP RO Community Name SNMP read only community name (default: public). Allow Dynamic LUN Masking With this configuration dynamic LUN masking is allowed (true) or not (false). 32 Management Tool

40 Network Object Object Tree 6.4 Network Object In this object the network infrastructure of the entire FlexFrame environment which is used to implement redundant connection of all the FlexFrame components using integrated switches is managed. The figure on the left side shows the Network object as an example. If a switch port is already connected to a NIC, the icon of the switch port is marked green. The relation then also appears in the wiring view. By selecting this object, the switch group part of the Controlling view is displayed in the lower split pane (see page 44). The upper split pane shows miscellaneous settings concerning the network (see Miscellaneous Network settings below). Management Tool 33

42 Storage Object Object Tree A switch group is typically used as a network unit for the redundant connection of the hosts for each system cabinet (19 rack). This is intended to reduce the cabling outside the system cabinet to a minimum. The switches within a group are connected in such a way that the hosts are connected with redundancy. The first two switches of a group are connected redundantly with the neighboring switch groups across switch group boundaries. Connecting switch groups to each other is in the responsibility of the customer. FlexFrame only provides uplink ports at the switch groups. Only two switch groups may be connected directly. 6.5 Storage Object In this object the central storage systems of the entire FlexFrame environment which can be accessed by all Application Nodes are managed. Operating systems (shared OSs) and application software are also stored centrally. Only the operating systems of the two servers of the Control Center are stored on their local disks and not in the NAS storage. The figure on the left side shows the Storage object as an example. If a NIC is already connected to a switch port, the icon of the NIC is marked green. The relation then also appears in the wiring view. By selecting this object, the NAS Storage view is displayed (see page 48). The NAS Details view is also displayed under the Storage NAS object. Management Tool 35

43 Object Tree Pools Object 6.6 Pools Object In this object the features of a pool within a FlexFrame environment are managed. Depending on the choosen object an appopriate view is opened. Pools are of central importance and have to be defined first. A pool contains multiple systems and is separated and protected from other pools by different network addresses and access controls (multi-client capability). All systems in a pool belongs to exactly one client. This is, for example, the client of a service provider who has a number of systems made available to him to use exclusively. Each pool contain one or more pool groups. A pool group is an additional grouping level within a pool. All Application Nodes with common characteristics maybe included in the same pool group, e.g. servers with the same operating systems or performance classes. In case of a failure the Application Nodes can replace themselves mutually (a Sap instance is then started on another Application Node of the group). For each new pool one pool group is automatically created. The figures below show the individual subobjects of the Pools object as examples. By selecting the Pools object, the Pools view is displayed (see page 43). By selecting the External Connectivity object the pool-specific External Connectivity view is displayed (see page 54). If a NIC is already connected to a switch port, the icon of the NIC is marked green. The relation then also appears in the wiring view. 36 Management Tool

44 Pools Object Object Tree By selecting the Sids object the SAP Services view is displayed (see page 51). In the upper split pane of the view you can manage the pool-specific UIDs and GIDs that might be necessary when installing and running the SAP services in the given pool. During installation the UIDs or GIDs given here are only used, when a SAP version or DB version that makes use of this user or group is actually installed. If there is no UID or GID given here for a user or a group actually needed for a SAP or DB installation, then a default value will be used. When migrating an existing SAP Installation to FlexFrame, the existing UIDs and GIDs should be used here. Management Tool 37

45 Object Tree Pools Object By selecting a pool (e.g. pool1) or the Groups object (and subobject below), the Application Nodes view is displayed (see page 45). The relevant display is object dependent. The left figure shows an example for a blade server (group2) and a PRIMERPOWER (group3). With blade servers, only the server blades are managed in the Pools object. The mamagement blade and the switch blades are managed in the Chassis object (see page 39). 38 Management Tool

46 Chassis Object Object Tree 6.7 Chassis Object In this object the management blade and the switch blades of all blade servers within a FlexFrame environment are managed. The view of this object displays the same information as the Application Nodes view, but only for blade servers. The figure on the left side shows the Chassis object as an example. With the Add action you can add the management blade and the switch blades for a new blade server. The switch blade types include the type Pass-Thru, which enables dedicated connections to specific server blades and also enables to use part of the server blades within FlexFrame and part of it outside of FlexFrame. The server blades for a blade server must be specified hereafter in the Pools... Servers object or under the Application Nodes tab as Application Nodes. With the Delete action you can delete the management blade and the switch blades of a blade server. If a NIC is already connected to a switch port, the icon of the NIC is marked green. The relation then also appears in the wiring view. If a server blade is already connected to a slot, the icon of the slot is marked green. Management Tool 39

47 Object Tree Global Connectivity Object 6.8 Global Connectivity Object In this object the global network connections are managed. For further information see page 25. The figure on the left side shows the Global Connectivity object as an example. Under the ClLanCons object you can define global Client LANs. 40 Management Tool

48 7 View Area 7.1 General Features Depending on the selected object in the object tree or on the selected tab in the tab bar, a view is opened in this area. This view consists of a table, a property list or of both of them in terms of split panes. A tab bar in the views is only displayed when you select the FlexFrame object in the object tree (see page 30). The figures in this chapter show the information when opening the tabs of the FlexFrame object view. The corresponding information will be also displayed when selecting another object (below the FlexFrame object) in the object tree. In this case, the view depends on the location of the object in the object tree. This means, the deeper you are in the structure the differentiated is the display of the information. If you select a leaf object you will see in the view area only the properties of the selected object (e.g.: Wiring View for Storage only, Wiring View for one switch group only or Application Nodes for one pool only). While describing the individual views the corresponding objects are specified. In the view area the values of all fields highlighted in white in the table as well as the values of the fields in the property lists can be changed via a pull-down menu or by direct input (the latter must be confirm with CR). If applicable, there are buttons above a table for carrying out actions. Each action carried out produces a new object-dependent subtree in the structured object tree. On page 57 you find an overview of all actions. Management Tool 41

50 Pools View View Area 7.3 Pools View This view shows all existing pools with their current LAN parameters as well as the DNS information. You can open this view also via the Pools object in the object tree (see page 36). Due to the table size the presentation of the Pools view is divided into a left part (first figure) and a right part (second figure) of the screen. Pool Name of the pool Network Network address of the individual LAN Netmask Netmask of the individual LAN VLAN ID VLAN ID of the individual LAN DNS Domain Name DNS domain name for the pool (alphanumeric,. and - are allowed) DNS Server DNS server for the pool (IPv4 format) With the actions Add Pool and Delete Pool you can add or delete pools. In the fields highlighted in white you can modify the general pool names, the host part of the IP addresses, the netmasks and the VLAN IDs of the different LANs as well as the DNS domain name and the DNS server by direct input. Failover concept for Application Nodes related to FA Agents: If a node in a pool group fails and no adequate spare node is found in the group of the failed node, the FA Agent can search a spare node in the special pool adminpool. This pool has a SPARE group, which provides global spare nodes for all pools of a FlexFrame landscape. The adminpool must not serve as a normal production pool. Management Tool 43

51 View Area Controlling View 7.4 Controlling View In this view the switch groups, the Control Nodes and associated pools are displayed with their current LAN parameters. You can open this view also via the Control Center object concerning the Control Node entries (see page 31) and via the Network object concerning the switch group entries (see page 33) in the object tree. If you open this view via the Control Center object, an additional area is displayed above the table. Here you can enter miscellaneous settings concerning the Control Center. Due to the table size the presentation of the Controlling view is divided into a left part (first figure) and a right part (second figure) of the screen. 44 Management Tool

A left mouse-click on the appropriate field opens a pull-down menu, in which you can select the desired association. In the other fields highlighted in white you can modify the host names of the switch groups and Control Nodes as well as the host parts of the IP addresses of the different LANs by direct input. 7.5 Application Nodes View In this view all existing Application Nodes of the FlexFrame environment on which the SAP services run are displayed with their current parameters. You can open this view object dependent also via different subentries of the Pools object in the object tree (see page 36), e.g. the information for a single pool is displayed under Pools - <pool_name> and for a single group under Pools - <pool_name> - Groups - <group_name>. Depending on the type of an Application Node, one or more lines exist. This is particularly important for blade servers with a chassis as they use common resources (management blade and switch blades) that need to be configured once only per blade chassis. All host names generated are used by FlexFrame system software. These host names are physical host names and not restricted by SAP conventions like virtual host names. So they may not be used by SAP applications. To provide network redundancy for PRIMEPOWER nodes with Solaris IPMP, additional test addresses are required. When they are created, these entries are added automatically as the types Solaris HA1 and Solaris HA2. Due to the table size the presentation of the Application Nodes view is divided into a left part (first figure) and a right part (second figure) of the screen. Management Tool 45

60 SAP Services View View Area Virtual host names and virtual IP addresses Virtual host names and the corresponding virtual IP addresses are used by applications to address the server on which an SAP instance is running. The virtual IP address is assigned to a physical host dynamically before an SAP instance is started. Thus, it identifies the actual host on which the SAP instance is running. If an SAP instance is moved to another server, this SAP instance always is addressable using the same virtual IP address. Virtual IP addresses are also used for communication from applications outside FlexFrame systems, i.e. SAP front ends such as SAPGUI. Virtual host names are formed as follows: <service_type>[<id>]<sid>[<-lan_type>] service_type db - database instance ci - central instance (ABAP) app - application instance (ABAP) ascs - ABAP SAP central services instance scs - JAVA SAP central services instance jc - JAVA central instance j - JAVA application instance lc - LiveCache instance ers - Enqueue Replication Service instance ID Instance number from 00 to 96 (except 2, 25, 43, 72 and 89) for the service type (left empty for db and lc).

61 View Area External Connectivity View 7.9 External Connectivity View With the Management Tool a pool-specific external connectivity can be planned. It leads to configuration of abstract external connectivity devices. For a pool-independent global connectivity see page 25. The switch ports connected to NICs of this external connectivity devices are configured with untagged VLAN switch ports in case of a single VLAN. In case of multiple VLANs, all will be configured as tagged. If tagged, devices plugged into these ports require interfaces using tagged VLANs. To be able to communicate, these VLANs have to be configured with the same VLAN IDs like the switch port and as configured with the Management Tool. A link aggregation for load balancing will not work and may block the entire network! In the External Connectivity view all network connections of the internal FlexFrame networks to the operator s corporate network are displayed with their current parameters. Entries in the various LAN segments may, for example, be necessary for backup servers or servers outside the FlexFrame environment. You can open this view also object dependent via the Pools <pool_name> - External Connectivity object in the object tree (see page 36).

73 Actions Adding Pool Groups Celerra SRDF-NAS Active/Passive Configuration In order to build a disaster tolerant FlexFrame configuration with SRDF mirrored EMC NAS systems, a special type of Celerra SRDF-NAS active/passive configuration has to be defined by applying the following procedure: The active Celerra must be the one that has an active data mover which is the volff device of the FlexFrame landscape. This system must be defined in a first step (Add NAS dialog) including storage LAN addresses and volumes for its active data movers. This Celerra system will also have at least one local standby data mover, which must be defined with no storage LAN addresses and no volumes, and has the property Local standby datamover set to true. Add the passive Celerra in a next step. The passive Celerra must have a number of RDF standby data movers equal to the sum of the number of active data movers that need to be protected by SRDF and their associated local standby data movers of the active Celerra. This attribute can not be set directly in the Add NAS dialog. Instead, add the Celerra with the correct total number of data movers. Then set the Remote partner property of this Celerra to point to the active Celerra. You can do this in the Remote partner drop-down box in the view that is displayed when selecting the passive Celerra in the object tree. Now you can set the Remote standby datamover property to true for each data mover that will be used as an RDF standby in the view that is displayed when selecting the concerned data mover in the object tree. These data movers must also be defined with no storage LAN addresses and no volumes Adding Pool Groups The action for adding a pool group opens the following dialog box.

78 Adding Switch Ports Actions 8.17 Adding Switch Ports The action for adding a switch port is carried out directly, no dialog box is opened Adding Volumes The action for adding a volume opens the following dialog box. NAS Device Volume Name Name of the NAS system witch contains the volume. Name of the volume (max 32 signs, only letters and numbers, have to start with a letter, volff is not allowed). A local standby or remote standby data mover must not possess volumes. This will be checked when validating the configuration by using the Validate Configuration function. If already existing, you have to delete the corresponding volumes by right-clicking on the volume and choosing Delete and adding them to an active data mover. If the volume has mount points, e.g. for SID specific sapdata, saplog, then you have to proceed with Adding Mount Points for Volumes as described in section 8.9, like you did it with the original volume earlier.
