Managed System for SAN Storage Agent User's Guide


Configuring devices for the storage agent to access

Figure 4 shows the results of completing Step 4. Client System and Step 5. Server.

Figure 4. Device information. Results of Steps 4 and 5.



Device information

Step 4. Client System

Do the following:

  1. Start the Device Driver
  2. Obtain Device Information. You will need this information for the drives in order to complete the task in Step 5. Server.

Start the Device Driver

As part of the storage agent installation, the TSM device driver is installed but not enabled or started on the client system. Do the following:

  1. Enable the device driver by entering the following command from a command prompt:
    tsmscsi /enable
    
    Note:If you have not added the storage agent path to the search path, you must first change to the directory where the storage agent program resides. By default, the path is c:\program files\tivoli\tsm\storageagent.

    You will receive a message similar to the following:

    +--------------------------------------------------------------------------------+
    |TSM Windows 2000 / Optical support is enabled on SANCLIENT.                     |
    +--------------------------------------------------------------------------------+

    Or

    +--------------------------------------------------------------------------------+
    |TSM Optical support is enabled on SANCLIENT.                                    |
    +--------------------------------------------------------------------------------+
    Note:The message says that optical support is enabled, however the Managed System for SAN feature does not support the use of optical devices on the SAN.
  2. Start the device driver by rebooting the client system. The device driver should automatically start at reboot.

Obtain Device Information

To later allow the storage agent to use the SAN devices via the drive mapping on the TSM server, you need to obtain the device name information for the drive mapping commands.

From an MS-DOS command line, enter the following command:

tsmdlst

You will see information similar to the following:

+--------------------------------------------------------------------------------+
|Computer Name:      SANCLIENT                                                   |
|TSM Device Driver:  Running                                                     |
|                                                                                |
|TSM Device Name  ID   LUN  Bus  Port   TSM Device Type  Device Identifier       |
|--------------------------------------------------------------------------------|
|mt8.2.0.1        8    0    0    1      3570             IBM     03570B12        |
|lb8.3.0.1        8    1    0    1      LIBRARY          IBM     03570B12        |
|mt8.4.0.1        9    0    0    1      3570             IBM     03570B12        |
|f:\              0    0    0    0      REMOVABLEFILE     n/a                    |
+--------------------------------------------------------------------------------+

You will need the information in the column labeled TSM Device Name to issue the drive mapping commands for these devices on the server (Step 5. Server).

Step 5. Server

The following is an overview of the steps that you need to do on the TSM server. For details, see Administrator's Guide. On the server, you will do the following:

  1. Map the SAN drives for each client. You will need the device names as seen by the storage agent on each client system. See Obtain Device Information. When you have the device names, issue the drive mapping commands. For example:
    define drivemapping iris sangroup drivea device=mt8.2.0.1
    define drivemapping iris sangroup driveb device=mt8.4.0.1
    
    Note:For the same device, the device name as known to the server will probably not match the device name as known to the storage agent. If you have a number of drives on the SAN, matching up drives from the viewpoint of a server with that from a client system may be difficult and could require trial-and-error methods.

See Administrator's Reference for details on the commands.

For a review of the results of the steps that you have just completed, see Figure 4.
