10 Chapter 1 Basic Functions Chapter 1 Basic Functions This chapter explains the functions that can be used when ism is introduced. ism provides the following basic functions necessary for disk array operations such as the function to display physical disk configuration in a disk array and logical disk configuration that can be recognized by the application server. Configuration display: A function to display the configuration information on the physical and logical components (resources) composing a disk array. State monitoring: A function to display the status of components (resources) composing a disk array. Configuration setting: A function to setup the disk array configurations and bind logical components. Failure monitoring: A function that to provide the information about failures had occurred in a disk array in real time. Log output: A function to output the operation history containing the information on failures and operation status to a system log and own log file. Event link: A function to notify an operator of the occurrence of a certain operating status or failure, and perform the defined actions on a server. With above six basic functions, more efficient operation of disk arrays can be achieved. The details of them are described in the following sections Confiiguratiion Diispllay The configuration display function is provided to display the information on the physical resource configuration in a disk array, logical disks recognized by application servers, and application servers. The configuration management of multiple disk arrays is possible with ism. They can be centrally monitored on an ism client with the same viewer.

Icon etc. etc. Table 1-2 Display Icons Status The disk array is under monitoring, and all disk array components are in the normal state. The icon s shape differs by disk array type. The disk array is under monitoring, and an event or failure (except a critical failure) that needs maintenance had occurred in any of the disk array components. (Note 1, 2) The disk array is under monitoring, and a critical failure had occurred in any of the disk array components. (Note 2) The disk array is under monitoring and a threshold excess had occurred in any of the pools for snapshot. Alternatively, an actual capacity threshold excess or actual capacity threshold (pre) excess had occurred in a virtual capacity pool. (Note 3) The disk array is out of monitoring or under configuration setting. The icon s shape varies depending on the disk array type. The disk array is out of monitoring or under configuration setting. If this icon is displayed, an event or failure (except a critical failure) that needs maintenance had occurred in any of the disk array components just before monitoring was stopped. I-18

27 Chapter 1 Basic Functions Icon Status The disk array is out of monitoring or under configuration setting. If this icon is displayed, a critical failure had occurred in any of the disk array components just before monitoring was stopped. The disk array is out of monitoring or under configuration setting. If this icon is displayed, a threshold excess had occurred in any of the pools just before monitoring was stopped. The disk array is out of monitoring. If this icon is displayed, the network settings of the disk array include an incorrect IP address, or the connection to the ism server failed. Note 1. You can choose or to show the status of the disk array where an event or failure (except critical failure) that needs maintenance had occurred. Refer to 2.2, Client Start/Stop for details of the switching method. Note 2. Whether a failure is critical or not is decided at a higher layer, and the icon is displayed accordingly. Refer to 1.2.2, Screen and Operation about the component status icon and display in higher layer. Note 3. If a threshold excess had occurred in a pool for snapshot or if an actual capacity threshold excess or actual capacity threshold (pre) excess had occurred in a virtual capacity pool, the icon is displayed. However, when any failure (including a critical failure) or event that needs maintenance had occurred, the display of this icon is preceded by that of the icon to show the general operating status of the disk array. For details on actions to be taken when a snapshot threshold excess had occurred, refer to the Snapshot User s Manual (Function Guide). For details on actions to be taken when a virtual capacity threshold excess had occurred, refer to the Thin Provisioning User s Manual. Note 4. The shaded icons indicate the status of the disk arrays that are currently out of monitoring. (ii) Disk Array Subsystem Name Displays an arbitrary name that you set to identify the disk array. Refer to 1.3, Nickname Setting for setting method. (iii) Status Displays the general operating status of the disk array. Ready: All disk array components are in normal operation.

You cannot select each component but each minimum replaceable unit composed of several components on the picture. If a component is not in normal operation, the same icon of a component shown in the lower part of the list is also placed on the corresponding unit in the upper graphic part of the list. States of the components which are not visible entities (such as temperature) are shown with colors of the cabinet. The [Start Blink] and [Stop Blink] buttons of cabinet service LED are displayed on the right side of the cabinet. By clicking those buttons, you can perform the same control as when selecting [Cabinet Service LED] from the menu. (v) Node Number Displays the node number (2 digits in hexadecimal). * Node-related information is displayed only for the disk array with node.

111 Chapter 1 Basic Functions 1..2 State Moniitoriing The state monitoring function is performed to monitor the occurrence of the following events in the disk array monitored from the ism server. <Event> Status transition of the components Change of a disk array name, a logical disk name and a port name Configuration change Threshold excess of the snapshot capacity in use Occurrence of a threshold excess or quota excess of the thin provisioning actual used capacity ism supports the polling mode to acquire the monitoring information in the fixed interval. When any of the above events is detected, ism not only reflects the detected event on the configuration control screen of an ism client but also outputs the message to various logs (system log, operation log). Besides, it can perform an action linked with the event detection such as running a script file. For log output and link function, refer to sections 1.5 Log Output and 1.6 Event Link in this manual.

113 Chapter 1 Basic Functions Screen and Operattiion This section describes how the state monitoring information is displayed, and how to start and stop monitoring through an ism client. (1) Monitoring information display Information monitored by the ism server is displayed as Message Output and Status Value Reflection via ism client. (a) Message Output When the status transition, name change, or configuration change is detected, messages corresponding to such events are output in the message display area of the main window. Example of message output at failure detection Sat Jan 6 02:08: Info ismrmond ism07102:state of PD(11h) has become failure. (Storage_1 productid=storage SN= No=00h-01h PoolNo=0000h PoolName=Pool0000)... (i) (i) The message indicates that a failure had occurred in the physical disk (with a resource type of 11h, product ID of Storage, serial number of , number of 00h-01h, pool number of 0000h, and pool name of Pool0000 ) of the disk array (whose disk array name is Storage_1 ). Example of message output at name change Sat Jan 6 02:08: Info ismrmond ism07201:disk Array, named Storage_1, has renamed to Storage_2. (SN= )... (i) (i) The message indicates that the disk array (whose name is Storage_1 and serial number is ) has been renamed to Storage_2. For details, refer to the Messages Handbook. (b) State Value Reflection State changes of components such as changes in status, names, or configurations are reflected in the configuration display area of the main window on an ism client. If an event such as failure, caution, or offline occurs in any of the components, the status value of the component in individual component layer is changed and the corresponding icon is also changed. Status in the component layer or the disk array layer changes depending on the status change in the individual component layer. For example, if any event that requires attention occurs in PD, the status of the PD in the component layer and the status of the disk array layer change to Ready (Maintenance) (See Table 1-18). Furthermore, when two events at different failure level simultaneously occur in the individual element layer, an event with higher failure level is always reflected on the upper layer. I-105

Host-related information is displayed if the disk array supports host information display. Information related to a partition, cache segment, and port is displayed for the disk array for which VirtualStoragePartitioning has been purchased. I-106

115 Chapter 1 Basic Functions 1. You can choose whether to use the icon to show the Ready(maintenance) status with the environment setting for the ism client. Refer to 2.2, Client Start/Stop for details of the switching method. 2. When a threshold excess occurs, icon is displayed if the states of the disk array layer, partition layer, and the component layer (pool or logical disk) are Ready or Ready (Maintenance). If, however, [Display Maintenance Status] is checked, an icon indicating the state of components is given precedence for display. 3. Shape or shading of the disk array icon varies depending on the type of disk array and the monitoring state. For further detailed information on the disk array icon, refer to Disk Array Information Display in this manual. (2) Monitoring Start/Stop In the ism server, monitoring is automatically carried out for the disk array specified by the Environment Definition file (ismsvr.conf) when the server starts-up. When you wish to temporarily stop/resume monitoring for the specific disk array due to maintenance or configuration changes, the following operation should be executed. In order to utilize this function, user level should be L3. (i) (ii) Select [Operation] [State monitor] [Start/Stop Monitoring] (ism client (Web GUI)) or [Operation] [Start/Stop Monitoring] (ism client (Win GUI)) From the menu, select to display the Start/Stop Monitoring screen. From [Disk Array Subsystem Name] on Monitoring Control Dialog, select (click) a disk array that you wish to start or stop monitoring. If you wish to start monitoring: Click [Start] button. If you wish to stop monitoring: Click [Stop] button. If you wish to stop the monitoring start/recovery process for a disk array whose monitoring status shows Starting demand or Wait Recovery. : Click [Break] button.

116 Chapter 1 Basic Functions 1..3 Niickname Settiing Nickname setting function is used via ism client to set an arbitrary disk array name, logical disk name (and disk OS Type), and port name for disk arrays (other than the E series) monitored by ism. If setting identical names with those acquired from business systems using the disk arrays, you will be able to control the disk arrays more efficiently. Once set, they can be acquired without having to reboot ism because the setting is registered inside a disk array. For an E series disk array, you can use this function not via ism but Storage Manager Express. For details on how to start it, refer to 2.2.4, Starting Storage Manager Express.

124 Chapter 1 Basic Functions 1..4 Diisk Array Moniitoriing for Faiillure All ism messages are reported on the message display area of client screen while the client is connected. This is a function to allow clients to monitor disk arrays for a failure. The following describes the function to monitor disk arrays for a failure Functtiion Overviiew ism s function to monitor disk arrays for a failure allows for: (1) Reporting all the messages in the message display area of the ism clients that are connected. (2) Saving displayed messages in text files in the PC where the ism client is installed (log collection). (3) Message-level-based user notification How tthe Functtiion Works What is shown for operation log is shown in the message display area. Each message is displayed with an icon showing the severity level clearly. The message which has already been displayed once also extracts to individual log file on the PC side. Whatever display status ism client may be on screen according to the message level, it has function for noticing the failure occurrence to the user. (1) Output to the message display area The same operation log that is extracted on the ism server side is displayed in the message display area. However, it displays only what is output during ism client connection. The message which shows connection/disconnection between ism client and server is also displayed as an individual message. After determining the message level, add the proper icon ( (Err) / (Warning) / (Notice, Info)) at the start of line. (2) Log collection Messages displayed in the message display area are reported to log files on the PC. Up to 1 MB data can be stored in one log file. If it exceeds 1 MB, it is renamed to an ism old file and a new ism log file is created. Because two files, OLDiSM.log and ism.log are used one after the other, a maximum of 2 MB file can be saved and more capacity is not needed. (3) User notification function Because the ism client is not always displayed in the foreground, a function to notify a failure to users according to the message levels is provided. When the message level is (Err) / (Warning), the button on the task bar blinks (ism client (Win GUI) only) and the notification button changes from to. Press the notification button or use the menu to stop notification, in which case the notification button returns from to. I-116

125 Chapter 1 Basic Functions 1..5 Log Output ism messages are reported to operation log and syslog. The following describes log output details Functtiion Overviiew ism s log output function allows for: (1) Output of messages to operation log. (2) Output of messages to syslog. (The function or facility is daemon). (3) Switching of output files when the maximum of operation log is exceeded How tthe Functtiion Works Operation log consists of a log file being reported, its generation file (backup file) and a generation management file saving the management information of generation files. An operation log is created on the log file saving directory (/opt/ismsvr/etc/log). The output destination can be changed by configuring the environment settings. Generation files are log file backups saved in sequence. They can be created up to 99. However, if the number of generation files exceeds the maximum, the oldest file will be overwritten. Switching of files or change of names are performed automatically, which remains transparent to users. Example: When 17 generation files have been created in the operation log. Currently editing New (i) Name of the generation file being updated ism_log.log Generation files 17 (ii) Name of the latest generation file ism_log17.log 16 Name of the oldest generation file (iii) Name of the generation management file ism_log01.log ism_log.cnt 01 Generation management file 17 Old I-117

126 Chapter 1 Basic Functions (1) Log file One message output by ism server is saved as one record in the log file being reported. When the log file exceeds the specified size, it is initialized after copying to a generation file. File size: 1 to 10 (MB) Default is 1 MB; the size can be from 1 to 10 (MB) File name: ism_log +.log (2) Generation file A generation file is a backup file of the log file. Up to 99 generation files can be created. The generation number of a file represents the order of the backup; the larger the number is, the newer the file is. However, the file with the largest number is not necessarily the newest one because overwriting is made from the file of the generation number 1 and subsequent files when the number of created files exceeds the maximum. For information about how to identify the newest file accurately, refer to (3) Generation management file. File name: ism_log + nn +.log Generation number: 01 to 99 (3) Generation management file A generation management file is a file that shows the latest information on the generation file numbers, and saves the information with 2-digit generation number (2 bytes). When the generation number of generation management file is 99, 01 is assigned as the next generation number. When no management file exists right after the installation of ism, or a number not within the range of 01 to 99 is specified by mistake, follow the instructions shown below: (i) Set the generation number to 01 for the next file to be processed. (ii) After backing up the information to a generation file, re-create the generation management file. File name: ism_log +.cnt I-118

137 Chapter 1 Basic Functions 1..6 Event Liink Event link function is one of the ism functions. With this function, actions such as reporting by mail or shell starting can be executed according to the specified definitions, based on messages from ism Functtiion Overviiew ism s event link function allows for: (1) Specification of mail addresses based on the combination of message number and message level, and sending messages to specified addresses. (2) Specification of shell scripts based on the combination of message number and message level, which achieves associated processing. (3) Dynamic modification of definitions by using the ism server command for modifying the link definition information without restarting the ism server. Operation administrator Operation administrator on remote site Storage Manager Program start Remote site Failure Local site User-specific reporting process can be set. Report can be sent to anywhere. Disk array Figure 1-59 Event Link I-129

138 Chapter 1 Basic Functions Outtlliine off Liink Deffiiniittiion and Processiing When a message is generated, a certain action is started as a link operation. The action must be defined in the link definition file (/etc/ismsvr/msgdrv.conf). Additionally, the template of mail must be defined as the mail template file. For details on the link definition file and mail template file, refer to B.1 Link Definition File How tthe Functtiion Works If the definition corresponding to the message number and message level of a message that has arrived is registered in the link definition file, the defined actions are executed. For actions, starting a shell takes precedence over mail transmission. If the next message is received while an action is ongoing, the actions for the next message will be executed after the actions to be executed for the message currently being handled are completed. If the same action has been specified more than once for the same message, the action is executed just once. In shell starting, full path of the temporary file where the message body (/opt/ismsvr/etc/msgdrv/nnnn.txt) is stored is sent as the first parameter. For shell scripts or programs that are started up by them, read the temporary file if necessary and receive the message. The environment (such as environment variables) where the shell is started up is the same as the environment where the ism was started up. Note that you have to use different settings (such as environment variables) depending on whether the OS is started by the system or the user. For mail, the mail template file is sent as mail to the defined SMTP server. If the sending mails to the SMTP server does not complete within 30 seconds, the sending is interrupted due to a time-out error. Timeout, SMTP error and shell starting failure are notified via message so that they can be checked on the operation log. For mail transmission and shell starting respectively, the upper limit of the processing count per unit time (one minute) is controlled. If the upper limit is exceeded, the exceeded link processing is canceled for a maximum of one minute. Because multiple link operations cannot be performed at the same time, up to 30 messages generated during a link operation will be stored in a buffer. If more messages are generated, the excess messages will be discarded. A loop may be formed if an error event with the event link function arrives at the event link function again and, therefore, the messages output by the event link function itself will not be subject to linking. I-130

139 Chapter 1 Basic Functions Deffiiniittiion Updatte Definitions are loaded when the ism server starts up. During this process, the link definition file and mail template file are loaded and reflected to event link operations. ismsvr update -m is an ism server command for modifying the link definition information. When entered, this command is notified to event link, reloads the link definition file and mail template file and dynamically changes control. If there is a definition error, the definition is not changed and operation continues with the previous definition. I-131

If you want to monitor a D series or E series disk array, be sure to use this procedure to start the client. JRE (Java Runtime Environment) needs to be installed when you use the ism client (Web GUI). JRE is stored in the ism CD. Refer to the Installation Guide for details on the installation method. For information on the extent of JRE that the ism client supports, refer to the Installation Guide. (1) Starting the client Log in with administrator authority (Administrators group), and enter the IP address (host name) of the server where the ism server to be connected is operating and Web browser connection port number in the URL of the Web browser to start the client. Example: When the ism server is connected successfully, the login screen appears. 1. Only users with Administrator authority can operate the ism client (Web GUI). The ism client (Web GUI) may start the installer, so start the Web browser as Administrator. 2. When using the ism client (Web GUI), set the URL of the ism server to be connected to Trusted sites of the Web browser. In addition, set [ActiveX controls and plug-ins] - [Run ActiveX controls and plug-ins] to [Enable] in the security settings of the Trusted sites. For details on the procedures of the settings, refer to the Installation Guide. 3. A security warning message may be displayed when an attempt to connect to the ism server is made. When you see the message, confirm that the issuer is NEC Corporation and click the [Execute] button. 4. The message describing that functions of Internet Explorer (or the program name of the Web browser you are using) are blocked may be displayed on the Windows Security Alert dialog when connecting to the ism server. When you see the message, unblock the Internet Explorer functions on the screen where you see the message, or configure the firewall to unblock the Internet Explorer (or the Web browser you are using) functions in advance. 5. Connecting to the ism server may fail if your web browser is configured to use a proxy server. If this occurs, configure exception for your browser so that proxy server is not used to connect to the ism server. II-10

161 Chapter 2 Normal Operation However, it is unnecessary to change proxy server settings when you use the ism client (Web GUI) and ism server on the same machine. Change the proxy server settings by following the steps below. 1) Select [Control Panel] [Internet Options] [Connections] tab. Then, click the [LAN Settings] button to open the Local Area Network (LAN) Settings dialog. 2) If [Use a proxy server for your LAN] is checked, click the [Advanced] button to open the Proxy Settings dialog; if the check box is not selected, the following steps are not necessary. 3) Add both the host name and IP address for the server to connect in [Do not use proxy server for addresses beginning with:]. 4) Check the JRE proxy settings according to the steps below. JRE Select [Control Panel] [Java Plug-in] [Proxies]. Then confirm whether [Use Browser Settings] is checked. If not checked, add both the host name and IP address for the server to connect in [No Proxy Host]. JRE 6 and 5.0 Select [Control Panel] [Java] [Network Settings]. Then confirm whether [Use browser settings] is checked. If not checked, select [Advanced] and add both the host name and IP address for the server to connect in [Exceptions]. 5) Close all the Web browsers in use and restart a Web browser. 6. If an attempt to start the ism client (Web GUI) fails and message [ ] is displayed, possible causes are as follows. Check the relevant machine environment. The protected mode is enabled. When Internet Explorer 7 is used as the Web browser, if the protected mode is enabled, startup fails.

(This information must be entered, if you specify multiple connections.) The specified connection name is displayed in the title bar of each client screen. When you have started multiple clients, you can use this name to determine the server for which information is shown. Figure 2-6 Example of Display of Connection Name in Title Bar II-16

167 Chapter 2 Normal Operation For a connection name, you cannot use a blank and those characters that cannot be used for a file name (\/:,;*? <> ). If you enter a name containing an unusable character and click the [OK] button, an error message is displayed; enter a connection name again. (ii) IP Address or DNS Name of Server Specify the IP address or DNS name of the ism server (this information must be entered). (iii) Port Number of Server In general, the port number does not need to be changed. Specify a port number only when the port is assigned particularly in the ism server setting. (iv) Client Name Specify the name to identify the client (this information must be entered). You can specify any name in alphanumeric characters as long as it is unique. (v) Port Number of Client The port number that is used to transfer data between client screens is displayed here. Generally a default port number is used. If the number is used by another program already, it must be changed. If multiple connections are defined, the client allocates default values from 8021 sequentially. Follow the steps below to edit the ismmain.ini file referenced by clients and to change a port number. ismmain.ini is stored in the folder displayed in [Folder Name] of [Connection Setting List]. If [Folder Name] displays the default connection, the file is stored in the installation folder. [CLIENT] PORT=8021 Change this value into a port number that is not currently used. 1. Numbers allowed for a port number are 1 to Specifying a disallowed number results in displaying an error dialog and termination. You can click the [Browse] button only if [SHELL] is selected in Action Type. 2. If the system has been activated, the specified value becomes effective after restart of the system. 3. ismmain.ini file contains various setting data. Do not edit other data than a client port number. If you edit other data, you may not be able to operate the system. (vi) Get Messages Select this box to save messages shown on the client status monitoring screen as text files on the PC. II-17

168 Chapter 2 Normal Operation (vii) Maintenance Status Use this option to switch the status of the upper structure to (Notice) when an event other than normal events occurs in an individual element layer. Normally, events ( (Warning) or (Err)) in the individual element layer are ignored in the upper structure because they do not affect operation. This option is selected when you want to check them in detail. When an event (e.g. LD failure) which affects operation occurs in the individual element layer, the upper structure fails (Err) regardless of this setting. The setting information is saved when you click [OK] after the setting ends. (viii) Logical Disk View Order [Logical Disk View Order] sets the order in which logical disks are initially displayed on each screen. Select [Number] or [Name (OS Type + Logical Disk Name)]. This setting changes the order in which columns are displayed in the logical disk list. The setting becomes effective after the client is restarted. Click OK to save the settings. If a connection is added, a shortcut icon for the ism client is created on the desktop and in the [Start] menu. (3) Connecting to the ism server When you select File and Connect after configuring the environment settings, an attempt to connect to the ism server is made. Figure 2-7 Connection Screen (i) User name Enter the user name and password registered with the ism server side. (ii) Password Enter the user name and password which are registered at the setting of the ism server side. User name/password can be saved individually. However, once a user name and a password are saved, any person can log in to the system using the registered user name and password. II-18

169 Chapter 2 Normal Operation If you click the [OK] button, the current disk array configuration is displayed on the configuration information display screen and messages are displayed sequentially on the failure monitoring screen. If there are disk arrays for which the BaseProduct license is not unlocked yet, the screen appears listing the disk arrays. (Figure 2-8) Figure 2-8 BaseProduct License Unlocked Disk Array Subsystem List Screen (4) User Level Users of the ism client are defined by the ism server. Depending on extent of permitted operations, the users are categorized as shown below. Table 2-3 User Level List Level 1 Authorized for disk array monitoring, state display, etc. For standard users Level 2 Authorized for operations on replication/snapshot/performance For operators monitoring/performance optimization function. Level 3 Authorized for all operations. For system administrators When connection is established, the user level is displayed on the ism client status line. The user can use functions permitted to the user level. For information on difference of permitted functions determined by levels, see the descriptions of functions. II-19

170 Chapter 2 Normal Operation (5) Icons on the Desktop and the [Start] Menu If you have deleted an icon for starting client from the desktop or the Start menu, or reinstall an ism client that has once been uninstalled, you can create the icon by following the procedure described below. <<Re-creating an icon on the desktop>> (i) Click [Start] [All Programs] ([Programs] for Windows 2000) [Storage Manager Client], and right-click the menu item for creating an icon on the desktop. (ii) From the menu shown by performing the previous step, select [Copy]. (iii) On Explorer, display the \Documents and Settings\All Users\Desktop folder on the system drive ( \Users\Public\Public Desktop folder (which is a hidden folder) on the system drive for Windows Vista). (iv) Right-click on the displayed folder, and select [Paste]. <<Re-creating an icon on the desktop and in the [Start] menu>> (i) On Explorer, display ismcl.exe located in the client s installation folder. (ii) Right-click the ismcl.exe icon and select [Create Shortcut]. (On Windows Vista, the shortcut is automatically created on the desktop.) (iii) Right-click the ismcl.exe icon and select [Properties], and the property screen is displayed. (iv) Select the [Shortcut] tab from the properties screen. (v) Following the double quotation of the ismcl.exe file name for [Target], add a blank and the name of the desired folder containing connection information. Example: C:\Program Files\NEC\iSMClient\iSMCL.exe SG1 Folder containing information on connecting destinations is located in the installation folder. View the ismmain.ini (connection IP) or ismstat.ini (connection name) found in each folder, and determine the name of the folder you want to specify. (vi) Select the [General] tab. (vii) In the input field located to the right of the icon, enter the name of the shortcut. Example: Storage Manager Client <connection name> (viii) Click the [OK] button to close the properties screen. (ix) To create an icon on the desktop, copy or move the icon created with the above steps to the \Documents and Settings\All Users\Desktop folder on the system drive ( \Users\Public\Public Desktop folder (which is a hidden folder) on the system drive for Windows Vista). (x) To create a menu item, copy or move the icon created with steps up to (viii) to \Documents and Settings\All Users\Start Menu\Programs\Storage Manager Client (default value) ( \ProgramData\Microsoft\Windows\Start Menu\Programs\iSM Client (default) (which is a hidden folder) on the system drive for Windows Vista). II-20

171 Chapter 2 Normal Operation Note the following when re-creating an icon: 1. Uninstalling an ism client deletes the icon on the desktop and the menu item. If you re-install a client after uninstalling it, copy the icon to an appropriate folder on the desktop before uninstalling it. After re-installing it, you can restore the icon before uninstallation by copying the saved icon to the \Documents and Settings\All Users\Desktop folder on the system drive (for the [Start] menu, the \Documents and Settings\All Users\Start Menu\Programs\Storage Manager Client (default value) folder on the system drive). * Re-install the ism client in the same folder where it existed before uninstallation, so that the icon reference will not become invalid. * For Windows Vista, you must specify different copy destination folders. Refer to steps (ix) and (x) in <<Re-creating an icon on the desktop and in the [Start] menu>>. 2. If you delete both an icon on the desktop and a menu item, the procedure for re-creating the icon will be cumbersome. For this reason, leave the menu item undeleted. 3. The name of the icon to be created on the desktop must be in the format of Storage Manager Client <connection name>. If you create the icon name in another format, the icon on the desktop will not be deleted during uninstallation. 4. The term icon, as used throughout the above explanation refers to shortcut icon. II-21

172 Chapter 2 Normal Operation Sttarttiing Functtiions The ism client has functions for configuration monitoring, failure monitoring, performance monitoring, performance optimization, replication operation, configuration setting, snapshot management, and data protection. In the screen that opens first (Figure 2-9 or 2-10), the configuration display area (upper left corner (i)) and the information list display area (upper right corner (ii)) are responsible for configuration monitoring. The message display area (lower area (iii)) is responsible for failure monitoring.
