With the Managed System for SAN feature, you can set up a SAN configuration in which a TSM client directly accesses a library device to read or write data. SAN data transfer requires setup on the server and on the client, and the installation of a storage agent on the client machine. The storage agent transfers data between the client and the storage device. See TSM Managed System for SAN Storage Agent User's Guide for details. See the Web site for details on clients that support the feature: http://www.tivoli.com/support/storage_mgr/tivolimain.html .
One task in configuring your systems to use this feature is to set up policy for the clients. Copy groups for these clients must point to the storage pool that is associated with the SAN devices. (Configuring TSM Clients to Directly Access SAN-Attached Devices describes how to configure the devices and define the storage pool.) Clients for which you have mapped the SAN drives in this storage pool can then use the SAN to send data directly to the device for backup, archive, restore, and retrieve.
One way to configure policy for clients is to define a separate policy domain in which the active policy set has a default management class with the required settings. Then register all clients using SAN data transfer to that domain. Do the following:
define domain sanclients description='Policy domain for clients using SAN devices'
define policyset sanclients base
For example, to define the management class that is named SANCLIENTMC, enter the following command:
define mgmtclass sanclients base sanclientmc
Then assign the new management class as the default:
assign defmgmtclass sanclients base sanclientmc
The storage pool must already be set up. The storage pool must point to a device class that is associated with the library for the SAN devices. See Configuring TSM Clients to Directly Access SAN-Attached Devices for details.
define copygroup sanclients base sanclientmc standard destination=sanpool
The storage pool must already be set up. The storage pool must point to a device class that is associated with the library for the SAN devices. See Configuring TSM Clients to Directly Access SAN-Attached Devices for details.
define copygroup sanclients base sanclientmc standard type=archive destination=sanpool
For example, to activate the BASE policy set in the SANCLIENTS policy domain, enter the following command:
activate policyset sanclients base
For example, to update the node SANCLIENT1, enter the following command:
update node sanclient1 domain=sanclients
If you choose not to define a separate policy domain with the appropriate management class as the default, you must define a new management class within an existing policy domain. Because the new management class is not the default for the policy domain, you must add an include statement to each client options file to bind all objects to that management class. For example, suppose sanclientmc is the name of the management class that you defined for clients that are using devices on a SAN. You want the client to be able to use the SAN for backing up any file on the c drive. Put the following line at the end of the client's include-exclude list:
include c:* sanclientmc
