Migrating an Existing TSM Server into a Cluster

To migrate an existing TSM server into a cluster, you can either move the clients or perform a backup and restore procedure. The choice depends primarily on the availability and capacity of other TSM server computers in your site and your familiarity with the backup and restore procedure.

Moving the Clients

If you move clients from a non-clustered TSM server computer to a clustered one, you can have the time to gradually migrate your users to the new system and not interrupt services. However, you must have the hardware needed to run two servers simultaneously. You can move clients in either of the following ways:

Using Backup and Restore

If you have limited hardware resources, you can add an existing TSM server to a cluster by using the backup and restore procedure outline here. For more detail, see the Administrator's Guide.

For example, suppose you have no hardware other than the two servers to be clustered and you plan to use the computer that is currently running the TSM server as a node. Follow this procedure to remove TSM from the computer and reinstall it in the cluster:

  1. Back up all disk storage pools to a copy storage pool.
  2. Back up the database of the existing TSM server.
  3. Perform the installation and configuration of the cluster.
  4. Restore the database to the clustered TSM server.
  5. Restore the disk storage pool volumes from the copy storage pool.
  6. After you verify that all your data is on the clustered server, delete the old server.
