Configuring TSM Clients to Directly Access SAN-Attached Devices

This section describes the tasks involved in configuring the TSM client and server so that the client can, via a storage agent, move its data to storage on a SAN. As part of the configuration, a storage agent is installed on the client system. See TSM Managed System for SAN Storage Agent User's Guide for detailed information on the storage agent. This function is provided by the Managed System for SAN feature.

Note:TCP/IP is the only protocol currently supported for communications between the storage agent and the TSM server.

TSM Client Setup

Setting up the client to directly access a storage device over a SAN consists of installing and configuring the storage agent on the TSM client machine and enabling the option for the API to allow the data movement. You also need to set up the TSM device driver. Thereafter, the client communicates with the storage agent, which in turn communicates with the TSM server. For details on these steps, see TSM Managed System for SAN Storage Agent User's Guide.

TSM Server Setup

  1. Obtain the library and drive information for the SAN library device. Look in the /dev/rmt directory for device names.
  2. Define a library named SANGROUP, using the SHARED=YES parameter.
    define library sangroup libtype=scsi device=/dev/0lb shared=yes
    
  3. Define the drives in the library.
    define drive sangroup drivea device=/dev/rmt/4mt element=1030
    define drive sangroup driveb device=/dev/rmt/5mt element=1031
    
  4. Define a device class for the drives.
    define devclass santape devtype=3570 mountretention=1 mountwait=10
     library=sangroup
    
    Note:Do not use a device type of GENERICTAPE for drives to be shared on a SAN with clients.
  5. Define a storage pool, SANPOOL.
    define stgpool sanpool santape description='SAN storage pool'
     maxscratch=50
    

    For each client for which you want to enable SAN data transfer, do the following:

  6. On the server, define the client's storage agent as if it were a server. The name must match the name specified during storage agent configuration. For example, if the storage agent's name is IRIS, issue the following command:
    define server iris serverpassword=jonquil
     hladdress=sanclient.tucson.ibm.com lladdress=1500
    
  7. On the client system, do the following:
    1. Start the TSM device driver.
    2. Determine the device name by which the storage agent knows the device.
    For details on these steps, see TSM Managed System for SAN Storage Agent User's Guide.
  8. On the server, define drive mapping for every drive that the storage agent will access, by using the DEFINE DRIVEMAPPING command. For the device name, specify the device name by which the storage agent knows the device.
    define drivemapping iris sangroup drivea device=mt5.0.0.1
    define drivemapping iris sangroup driveb device=mt5.2.0.1
    
  9. Set up the policy so that the client uses the new storage pool as the destination for backup operations. See Configuring Policy for Managed System for SAN for details.
  10. On the client system, do the following:
    1. Start the storage agent.
    2. Start a backup operation to verify that the setup is complete.
    For details on these steps, see TSM Managed System for SAN Storage Agent User's Guide.
