15 1 Introduction Clustering Overview The computer industry has been using a wide range of solutions to counteract the effects of computer system downtime for years. Previously, these solutions have been costly to set up and maintain. Historically, only mission-critical applications, such as those controlling stock exchange trading floors and aerospace mission controls, were deemed important enough to justify proprietary clustering solutions. However, as businesses have increased their reliance on computer systems in day-to-day operations, the amount of acceptable downtime has decreased. Today, a new class of applications exists. They are business-critical applications that are key to business success but not significant enough to justify the high price tag of a traditional clustering solution. More applications are becoming business-critical; their failure causes lost revenue, decreased productivity, and potentially, customer dissatisfaction. As business critical applications have evolved to run on industry standard platforms, clustering technology has also been extended into that environment. These new clustering solutions use industry-standard hardware and software, thereby providing key clustering features at a lower price than proprietary clustering systems. Before examining the features and benefits of Compaq ProLiant Clusters for NetWare 5.1, it is helpful to understand the concepts and terminology of these traditional cluster systems. Compaq ProLiant Cluster for NetWare 5.1 with the RA4000/RA4100 Storage Subsystem 1-1

16 Introduction Clusters Defined Clustering is the integration of software and hardware that enables a set of loosely coupled servers and storage to operate as a single system, presenting a single entity to clients. As a cluster, the group of servers and storage offers a level of availability greatly exceeding the reliability of a stand-alone server. This translates into increased performance and greater data availability for end users. Figure 1-1 illustrates a cluster with six nodes and one shared storage array. Shared Storage Node 5 Node 3 Node 1 Fibre Channel Node 2 Node 4 Node 6 Storage Hub/Switch Client LAN and Cluster Interconnect Clients Figure 1-1: Six-node cluster example The Compaq ProLiant Cluster for NetWare 5.1 configured with the Compaq StorageWorks RA4000 or RA4100 Storage Subsystem delivers high availability with automatic failover of all network resources and responsibilities in the event of a failure. Should one server in the cluster lose access to the shared storage and network, the other server assumes the responsibilities of the downed server. The ProLiant Cluster for NetWare 5.1 supports up to eight nodes. The ProLiant Cluster for NetWare 5.1 also supports full switched fabric and Fibre Channel Arbitrated Loop Storage Area Networks (SANs), allowing customers to utilize the cluster for medium- and large-scale SAN environments. 1-2 Compaq ProLiant Cluster for NetWare 5.1 with the RA4000/RA4100 Storage Subsystem

17 Introduction Causes of Downtime Computer downtime is the period of time that a computer system cannot meet the requests of its users. The following are the leading causes of downtime: Planned service In a cluster, a single server can be taken offline, while another server takes on the workload of the downed server. This allows planned service to occur with only minimal interruption to the overall system operation. Software failures Because clustering provides a mechanism to automatically fail over processes when a discernible software failure occurs, the overall system operation can continue with only minimal interruption. Hardware failures If it is determined that a hardware failure will result in system downtime, the cluster will fail over processes from one node to another, allowing the overall system operation to continue with little interruption. Human error Inadvertent errors, such as accidentally disconnecting a power cord, are common causes of downtime. The cluster can detect these errors and allow system operation to continue. Cost of Downtime The driving force behind the high-availability systems has been the elimination of costs associated with downtime. The cost of downtime formula must include several factors. Among these are: Productivity loss IM costs Lost transactions Customer or end user dissatisfaction Compaq ProLiant Cluster for NetWare 5.1 with the RA4000/RA4100 Storage Subsystem 1-3

18 Introduction Each factor is weighted differently, depending on the critical nature of each factor as it pertains to your business and to your specific application systems. For example, downtime during peak hours of a point-of-sale operation would have a much greater impact on customer satisfaction issues than downtime in an end-of-day server backup operation. To understand the true cost of computer downtime in your business environment, you must examine the impact and contribution to increased costs of each factor as it applies to your business-critical applications. Benefits of Clustering With the causes enumerated and the costs understood, it is clear that NetWare Cluster Services clustering software running on ProLiant servers can eliminate your concerns and ease your tightening networking budget through: Availability Simply defined, availability is the measure of how well a computer system can continuously deliver services to clients. This is dependent upon the system s ability to prevent or recover from failures or faults. Scalability Clustering for scalability means increasing performance beyond that of a single computer node by adding more nodes to the cluster. Performance scalability across cluster nodes is difficult to achieve and requires not only scalable hardware, but also scalable software, for example, a parallel database. Serviceability The ability to perform online maintenance (that is, make hardware and software changes while the system remains running and available to users) reduces the need to respond quickly to maintenance issues. Manageability Management of the cluster is simpler and more efficient because management activities for the entire cluster can be performed from a single management workstation. Lower Total Cost of Ownership Increased availability reduces lost revenue and customer dissatisfaction caused by downtime. Costs are also reduced by a reduction in priority repairs, more efficient system management, and less disruptive maintenance. 1-4 Compaq ProLiant Cluster for NetWare 5.1 with the RA4000/RA4100 Storage Subsystem

21 Architectural Overview A typical ProLiant Cluster for NetWare 5.1 consists of the following components: Two or more Compaq ProLiant servers Shared storage components: One or more Compaq StorageWorks RAID Array 4000 (RA4000) or Compaq StorageWorks RAID Array 4100 (RA4100) Storage Subsystems with RA4000 Controllers Compaq StorageWorks Fibre Channel Host Adapters Compaq StorageWorks Fibre Channel Storage Hubs, Fibre Channel Arbitrated Loop Switches, or Fibre Channel SAN Switches Gigabit Interface Connectors (GBICs) and Fibre Channel cables Network Interface Controllers for the public LAN and cluster interconnect Compaq ProLiant Servers A ProLiant cluster supports up to eight ProLiant servers. Each server in the cluster must have one local hard drive. In addition, Compaq recommends at least 256 MB of RAM in each server. For an up-to-date list of cluster-certified servers, see the Compaq ProLiant Cluster for NetWare 5 Certification Matrix, available at: Features of ProLiant Servers ProLiant servers include many reliability features that provide a solid foundation for effective clustered server solutions. Components used to increase reliability and manageability in the ProLiant servers include: Hot-pluggable hard drives Uninterruptible power supplies (optional) Redundant power supplies ECC memory 2-2 Compaq ProLiant Cluster for NetWare 5.1 with the RA4000/RA4100 Storage Subsystem

22 Architectural Overview Offline backup processor Error Checking and Correcting (ECC)-protected processor-memory bus Redundant Processor power modules Hot plug PCI slots (in some servers) Redundant cooling fans Easy installation through SmartStart Manageability through Compaq Insight Manager Minimum Server Requirements ProLiant servers to be used in a ProLiant Cluster for NetWare 5.1 must meet the following minimum requirements: At least 256 MB of memory At least one local system hard drive At least one Fibre Channel PCI Host Adapter At least one Ethernet controller Shared Storage Components The ProLiant Cluster for NetWare 5.1 is based on an architecture in which clustered servers share access to a common set of hard drives. ProLiant Cluster for NetWare 5.1 requires all shared data to be stored in an external storage system in order for the data to be readily accessible from each cluster node and to implement the necessary quorum arbitration. The shared storage components include: Rack-mountable or Tower model RA4000 or RA4100 Storage Subsystem Fibre Channel Storage Hub, Fibre Channel Arbitrated Loop Switch, or Fibre Channel SAN Switch RA4000 Array Controller Compaq ProLiant Cluster for NetWare 5.1 with the RA4000/RA4100 Storage Subsystem 2-3

23 Architectural Overview Fibre Channel Host Adapter Fibre Channel cables and Gigabit Interface Converters (GBICs) RA4000 and RA4100 Storage Subsystems The shared external storage is provided by the RA4000 and RA4100 Storage Subsystems. The RA4000 and RA4100 are scalable, reliable storage subsystems designed to meet the needs for enterprise storage capacity and performance using Fibre Channel Arbitrated Loop or Fibre Channel Fabric interconnect technology. The RA4000 and RA4100 bring significant advantages to clustering, including: 100 MB/sec throughput with the added performance benefit of RAID configurations and ECC battery backup cache. This enables faster mount times and more reliable disk link schemes critical to cluster operation. Use of standard short wave or long-wave Fibre Channel cabling. Increased and easier connectivity through Fibre Channel Arbitrated Loop or Fibre Channel Fabric SAN topologies. Fibre Channel cabling eliminates the need for terminators, splitters, signal enhancers, and device IDs. Reliable transmission of data in the ProLiant Cluster s multi-node, shared storage environment. RAID configurations using hot pluggable drives. This provides faster performance while protecting against hard disk errors, and also provides the capability to expand storage capacity while the drives are online. Battery backup ECC cache, which provides even higher levels of performance and guards against power failures. Manageability through Compaq Insight Manager for thorough hardware status reporting and automatic failure notification. The RA4000/RA4100 storage chassis contains the disk drives, power supply, and array controller. The storage chassis can hold twelve 1-inch or, in the RA4000 only, eight 1.6-inch Wide-Ultra SCSI-3 drives. The chassis comes in both a rack and a tower model. 2-4 Compaq ProLiant Cluster for NetWare 5.1 with the RA4000/RA4100 Storage Subsystem

24 Architectural Overview Each ProLiant Cluster for NetWare 5.1 must have at least one RA4000 or RA4100 Storage Subsystem as external shared storage. The storage subsystems are connected to the cluster nodes in either a Fibre Channel Arbitrated Loop (FC-AL) topology using FC-AL Storage Hubs or FC-AL Switches, or a Fibre Channel Fabric topology using Fibre Channel SAN Switches. With the storage subsystem connected to cluster servers through the storage hubs, FC-AL Switches, or SAN Switches, you can independently manage shared volumes from the cluster servers as needed by your application and environment. Fibre Channel Storage Hub The Fibre Channel Storage Hub can be used to create the I/O paths between the cluster nodes and storage subsystems in clusters that use the Fibre Channel Arbitrated Loop topology. The Fibre Channel Storage Hub 7 and Fibre Channel Storage Hub 12 are supported. As the names imply, the Fibre Channel Storage Hub 7 and the Fibre Channel Storage Hub 12 contain seven and twelve ports, respectively. Using the storage hubs in a cluster environment will consume at least two ports for server connections, allowing up to five storage subsystems on the Fibre Channel Storage Hub 7 and ten storage systems on the Fibre Channel Storage Hub 12. In general, the total number of cluster nodes and storage devices cannot exceed the number of available Fibre Channel ports on the storage hubs. NOTE: Storage hubs cannot be cascaded; that is, they cannot be interconnected with other storage hubs. Fibre Channel Arbitrated Loop Switch The Fibre Channel Arbitrated Loop (FC-AL) Switch can be used to create the I/O paths between cluster nodes and shared storage in clusters that use the FC-AL topology. The FC-AL Switch has eight ports. Using the switches in a cluster environment will consume at least two ports for server connections, allowing up to six storage subsystems in the cluster. A 3-port expansion module is available for the FC-AL Switch, providing a total of 11 ports. Up to nine storage subsystems can be connected to the 11-port FC-AL Switch in a 2-node cluster. Compaq ProLiant Cluster for NetWare 5.1 with the RA4000/RA4100 Storage Subsystem 2-5

25 Architectural Overview Two FC-AL Switches can be cascaded; that is a FC-AL Switch can be interconnected with another FC-AL Switch to increase the number of available ports. Cascading two 11-port switches provides a total of 20 ports for servers and storage devices (the other two ports being used for the interswitch link). A FC-AL Switch can also be cascaded with a SAN Switch. For details on how to cascade a FC-AL Switch with a SAN Switch, see the Compaq StorageWorks RA4x00 Based SAN Solution Guide. Fibre Channel SAN Switch Fibre Channel SAN Switches are used to create the I/O paths between cluster nodes and shared storage subsystems in clusters that use the Fibre Channel Fabric SAN topology. An 8-port SAN Switch and a 16-port SAN Switch are available. Using the SAN Switches in a cluster environment will require at least two ports for server connections, allowing up to six storage subsystems on the 8-port switch and 14 storage subsystems on the 16-port switch. Two SAN Switches can be cascaded; that is, a SAN Switch can be interconnected with another SAN Switch to increase the number of available ports. For example, cascading two 16-port SAN Switches provides a total of 30 available ports for servers and storage devices (the other two ports being used for the interswitch link). A SAN Switch can also be cascaded with a FC-AL Switch. RA4000 Controller An RA4000 Controller resides in the back of the RA4000 or RA4100, and provides the Fibre Channel interface to connect to the cluster servers. To increase storage fault tolerance, the RA4000 Controller provides RAID capabilities. The RA4000 Controller supports RAID 0, 1, 4, and 5, as well as online capacity expansion and pre-failure notification for hard drives. In addition, the RA4000 Controller provides memory for user-configurable read and write cache to enhance RAID performance. The cache on the Array Accelerator is equipped with onboard rechargeable batteries, ensuring that the cached data is safe even with equipment failure or power outage. 2-6 Compaq ProLiant Cluster for NetWare 5.1 with the RA4000/RA4100 Storage Subsystem

26 Architectural Overview Typically, an RA4000 or RA4100 is configured with a single RA4000 controller. However, for a higher level of availability, an additional RA4000 Controller can be added to provide a backup for the primary RA4000 Controller. See Chapter 6, Configuring the I/O Paths and Communication Links for High Availability, for details. Fibre Channel Host Adapter The Compaq Fibre Channel Host Adapters (host bus adapter) serve as the interface for the servers to the RA4000s or RA4100s through the fiber optic cables. At least one host bus adapter is required in each cluster node. For higher availability, an additional host bus adapter can be added to each node to provide a backup for the primary host bus adapter, as described in Chapter 6, Configuring the I/O Paths and Communication Links for High Availability. Gigabit Interface Converters Gigabit Interface Converters (GBICs) are industry-standard connection devices that hot-plug into the Fibre Channel Storage Hubs or FC-AL Switches and RA4000 Controllers. GBICs convert serial electrical signals into optical signals for transmission across Fibre Channel media. GBICs also convert optical signals received from the Fibre Channel media into electrical signals. A GBIC is required on each end of the cables connecting the storage subsystem to the servers. The ProLiant Cluster for NetWare 5.1 supports both short-wave and long-wave GBICs. Short-wave GBICs allow for cable lengths of up to 500 meters, while longwave GBICs allow for cable lengths of up to 10 kilometers. Cluster Communication Components Cluster communication occurs over two types of network connections. These are the cluster interconnect and the public LAN connection. Compaq ProLiant Cluster for NetWare 5.1 with the RA4000/RA4100 Storage Subsystem 2-7

27 Architectural Overview Cluster Interconnect Public LAN The cluster interconnect is used to pass information from one cluster node to another. Specifically, the cluster interconnect is used to: Communicate cluster status. Send and receive heartbeat (a signal that the server is still operational). In a ProLiant Cluster for NetWare 5.1, the cluster interconnect should be bound to the same Network Interface Controller used for the public LAN connection, so that intra-cluster communication and cluster-to-client communication occur over the same network. A backup cluster interconnect is provided by the Fibre Channel link to a shared disk drive used for quorum arbitration, a scheme whereby each cluster server can check on the availability of the other servers. Public LAN communication consists of requests and responses between cluster nodes and network clients. The public LAN hardware requirements for a ProLiant cluster are the same as for a standalone server configuration. Network Controllers Compaq offers the following Network Interface Controllers: Netelligent 10/100 Fast Ethernet 10/100 These controllers are available in both single-port and dual-port versions. For added fault tolerance, both controllers support Advanced Network Fault Detection and Correction. In addition, the Netelligent controller supports Network Fault Tolerance. These technologies enable you to configure controller teams consisting of a primary controller and a redundant backup controller. 2-8 Compaq ProLiant Cluster for NetWare 5.1 with the RA4000/RA4100 Storage Subsystem

Failovers are transparent and non-disruptive to applications. Secure Path Manager is the client graphical user interface application used to monitor and manage the Secure Path environment. Secure Path Manager displays a graphical presentation of the current multiple I/O path environment and indicates the location and state of all configured storage units on each path Compaq ProLiant Cluster for NetWare 5.1 with the RA4000/RA4100 Storage Subsystem

34 3 Planning and Preparation This section describes planning activities that will simplify the installation and configuring of your ProLiant cluster. These activities include: Planning the cluster naming scheme Planning the IP address scheme Planning high availability options Planning for Server and Resource Names For ease of administration of cluster resources it is important to use simple, easy-to-remember names for servers, clients, and network resources. You decide these names before beginning the installation procedures. Some of the names you will need are: Server names Tree name Cluster name Volume names Cluster resource names Compaq ProLiant Cluster for NetWare 5.1 with the RA4000/RA4100 Storage Subsystem 3-1

35 Planning and Preparation Planning for IP Addresses NetWare Cluster Services is closely integrated with the NetWare 5.1 operating system. Unlike past versions of NetWare, both NetWare 5.1 and NetWare Cluster Services make extensive use of the TCP/IP protocol. TCP/IP requires IP addresses for the following: Cluster servers Cluster clients Cluster interconnect (normally over the public LAN and the Fibre Channel interconnect) Cluster resources (applications, volumes, and services) The following figure shows the IP addresses in a typical cluster configuration. 3-2 Compaq ProLiant Cluster for NetWare 5.1 with the RA4000/RA4100 Storage Subsystem

36 Planning and Preparation Client Client IP Address x.y.z.10 Public LAN and Cluster Interconnect IP Address x.y.z.20 Cluster Server Cluster Server Application Network Interface Card IP Address x.y.z.1 IP Address x.y.z.2 Network Interface Card Application IP Address x.y.z.101 IP Address x.y.z.102 Cluster Volumes IP Address x.y.z.103 IP Address x.y.z.104 Figure 3-1: IP address assignment example IP address planning should be done with a view toward ensuring ease of cluster manageability. A recommended technique for assigning IP addresses is to reserve blocks of IP addresses for related items in the cluster. For example (assume a subnet mask of ): Reserve addresses through for cluster nodes. Compaq ProLiant Cluster for NetWare 5.1 with the RA4000/RA4100 Storage Subsystem 3-3

37 Planning and Preparation Reserve addresses through for cluster resources. Use remaining addresses for clients and non-cluster applications. NOTE: Check all IP addresses to ensure they are valid. Planning Availability Options Before configuring your ProLiant cluster, you should decide which availability options you want for increased availability of the shared storage I/O paths and the cluster communication links, and obtain and install the necessary hardware components. Planning Cluster Configurations for Fibre Channel Fabrics In a cluster that uses the Fibre Channel Fabric SAN topology, you can increase the availability of the I/O paths to the cluster s shared storage in the following ways: By adding redundant Fibre Channel Host Adapters and RA4000 Controllers to provide redundant I/O paths between the cluster servers and shared storage. This requires the use of Secure Path to automatically manage the redundant paths. By adding a separate, redundant Fibre Channel Fabric. This protects against failure of one of the Fibre Channel Fabrics. Configuring a redundant Fibre Channel Fabric requires additional Fibre Channel Host Adapters, RA4000 Controllers, Fibre Channel SAN Switches, and cables. Redundant Fibre Channel Fabrics provide the highest level of availability in a cluster that uses the Fibre Channel Fabric SAN topology. For more information on achieving high availability through redundancy, see Chapter 6, Configuring the I/O Paths and Communication Links for High Availability. 3-4 Compaq ProLiant Cluster for NetWare 5.1 with the RA4000/RA4100 Storage Subsystem

38 Planning and Preparation Planning Cluster Configurations for Fibre Channel Arbitrated Loops In a cluster that uses the Fibre Channel Storage Hub or FC-AL Switch, you can increase the availability of the I/O paths to the cluster s shared storage in the following ways: By adding redundant Fibre Channel Host Adapters and RA4000 Controllers to provide redundant I/O paths between the cluster servers and shared storage. This requires the use of Secure Path to automatically manage the redundant paths. By adding a separate, redundant FC-AL. This protects against failure of one of the FC-ALs. Configuring a redundant FC-AL requires additional Fibre Channel Host Adapters, RA4000 Controllers, Fibre Channel Storage Hubs or FC-AL Switches, and cables. Redundant FC-ALs provide the highest level of availability in a cluster that uses the FC-AL topology. For more information on achieving high availability through redundancy, see Chapter 6, Configuring the I/O Paths and Communication Links for High Availability. Planning for Redundant Cluster Communication Links Advanced Network Fault Detection and Correction (ANFDC) and Network Fault Tolerance (NFT) are two technologies that increase the availability of the cluster communication links by enabling you to configure redundant hardware components along those links. For more information on how to configure these options and descriptions of the Network Interface Controllers that support them, see Chapter 6, Configuring the I/O Paths and Communication Links for High Availability.

41 Installation and Configuration Before running SmartStart: Be sure you have the latest version of SmartStart. Be sure that you have added all required hardware components to your ProLiant cluster. Power off all storage subsystems. This will eliminate the possibility of confusion over where the NetWare software is installed. It will also ensure that the installation process does not overwrite configurations from each installation of the cluster servers (since they operate in a shared storage environment). You will perform the installation procedures individually on each cluster node. Be aware that the first server (if not already part of a known network) will automatically install and create the Directory Tree. IMPORTANT: After starting the SmartStart installation procedure, do not remove the SmartStart CD or Server Profile Disk unless prompted to do so by the installation program. If they are mistakenly removed, you will need to repeat the entire SmartStart procedure from the beginning. IMPORTANT: The SYS volume must be installed on the local hard disk and not on a shared storage system. To avoid the possibility of mistakenly installing the SYS volume on a shared storage system, power off all shared storage systems before performing this procedure. To set up your server using SmartStart: 1. Insert the SmartStart CD in the CD-ROM drive on one of the cluster servers and allow the server to boot from the CD. The server checks for a previous hardware configuration and operating system installation. If the system has been previously configured, SmartStart detects this and gives you the opportunity to do following: Run the System Configuration Utility. Run the Array Configuration Utility (if SMART-2 is installed). Create/Update the System Partition. Run the System Erase Utility. Create Support Software. Exit SmartStart. Compaq ProLiant Cluster for NetWare 5.1 with the RA4000/RA4100 Storage Subsystem 4-3

Answer Yes to this prompt. Compaq ProLiant Cluster for NetWare 5.1 with the RA4000/RA4100 Storage Subsystem 5-19

115 Cluster Administration You can also view details about attached storage devices by entering a LIST DEVICES command at the system console prompt to display a screen similar to the following: This completes the procedure to add a storage subsystem. You can now create cluster-enabled volumes as needed. Creating a Cluster-Enabled Volume If you plan on using a shared disk system in your cluster and need to create new NetWare volumes, those volumes must be created using the same cluster server. The server used to create the volumes should already have NSS installed and running. After creating the volumes, bring up the other servers in the cluster. Depending on your configuration, the new volumes will either mount automatically when resources that require them start or will have to be mounted manually on individual servers after they are up. If you have a volume that is not being managed by NetWare Cluster Services and is not shared storage, you must manually activate that volume before you can access it. Otherwise, the volume will be deactivated by the command: NSS/ AUTODEACTIVATE VOLUME=ALL 5-20 Compaq ProLiant Cluster for NetWare 5.1 with the RA4000/RA4100 Storage Subsystem

116 Cluster Administration in the AUTOEXEC.NCF file. To manually activate a non-shared volume, enter the following command at the server console: NSS/ ACTIVATE=volume-name You must then manually mount the volume by entering: NSS/ MOUNT volume-name In order for clients to be able to access volumes on shared storage, you must clusterenable the volumes. Cluster-enabling a volume allows it to be moved or mounted on different servers in the cluster during failovers or when migration is necessary. Creating and cluster-enabling a volume involves these tasks: Allocate space for a new volume object. Create an NSS volume. Convert the NSS volume to a cluster volume object. Note that some server applications do not require client access to volumes; for those applications, cluster-enabling volumes might not be necessary. Once the volumes are cluster-enabled, they can be managed by NetWare Cluster Services and are available to all cluster clients. NOTE: Traditionally in the NetWare environment, volumes were associated with, or attached to, a physical server. On client workstations, this attachment was indicated by the path notation server/volume. This path limitation was not conducive to seamless failovers in a clustered environment because it required clients to remap their drives to the appropriate physical server. ProLiant Cluster for NetWare 5.1 uses a virtual volume: server path notation, where the volume path is attached to the cluster instead of a physical server. As long as the cluster is up and running, the volume is available to the client without the need for remapping or reconfiguring.

131 Cluster Administration Enabling or Disabling Selective Storage Presentation The ProLiant Cluster for NetWare 5.1 supports Selective Storage Presentation. Selective Storage Presentation enables you to grant or deny access from each cluster node to specific logical drives on shared storage. Selective Storage Presentation is typically used to maintain data integrity in heterogeneous environments (that is, environments in which both clustered and nonclustered servers, as well as servers with different operating systems, share access to the same storage arrays). Selective Storage Presentation allows multiple servers to share access to the same shared storage array safely, with each server s storage presented exclusively to the server or servers that are allowed to access that storage. In a typical ProLiant cluster environment, however, all cluster nodes should have access to all logical drives on shared storage. You can ensure this access by disabling Selective Storage Presentation on all nodes for each logical drive on shared storage. Note that enabling Selective Storage Presentation on a node for a logical drive means that all other nodes that will access that drive must also have Selective Storage Presentation enabled for that drive; otherwise, they will be denied access to the drive. For details on configuring Selective Storage Presentation, see the Compaq StorageWorks RA4X00 Based SAN Solution User Guide. You enable or disable Selective Storage Presentation by using the CPQONLIN utility. To enable or disable Selective Storage Presentation: 1. On a cluster server, start the CPQONLIN utility. 2. Select Array Configuration Utility and press the Enter key Compaq ProLiant Cluster for NetWare 5.1 with the RA4000/RA4100 Storage Subsystem

132 Cluster Administration 3. Select the array controller for which you want to enable or disable Selective Storage Presentation, then press the Enter key. The next screen shows the logical arrays configured for the array controller you selected. The Logical Drive box lists available options, including either Enable SSP (if Selective Storage Presentation is currently disabled) or Disable SSP (if Selective Storage Presentation is currently enabled). 4. To change the SSP setting for a logical drive, select the drive, select either Enable SSP or Disable SSP, then press the Enter Key.

133 Cluster Administration If you are enabling SSP, the following warning is displayed and you are allowed to confirm your choice: 5. Exit from the CPQONLIN utility. You can use the LIST DEVICES utility to see which logical drives are visible from a given cluster node. For simple example, suppose a cluster consists of two nodes and a shared storage subsystem with two logical drives configured. If SSP is disabled for both the Server1 and Server2 connections to both drives, both drives are visible from both nodes, as shown by the following LIST DEVICES displays: From Server1: Two logical drives visible 5-38 Compaq ProLiant Cluster for NetWare 5.1 with the RA4000/RA4100 Storage Subsystem
