Tivoli Storage Manager for Windows Quick Start
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.
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:
- You can register clients with the new clustered TSM server. Have
them perform a full backup of their data to the clustered server. Once
you are sure the client's data is now safely on the clustered server,
that client can be deleted from the old server. Once all clients have
been moved to the clustered server, the old server can be eliminated.
- You can export the clients from the old server and import those clients
into the clustered server. After you have verified that a client's
data is on the clustered server, you can delete that client from the old
server. After you have imported all clients to the clustered server,
you can delete the old server.
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:
- Back up all disk storage pools to a copy storage pool.
- Back up the database of the existing TSM server.
- Perform the installation and configuration of the cluster.
- Restore the database to the clustered TSM server.
- Restore the disk storage pool volumes from the copy storage pool.
- After you verify that all your data is on the clustered server, delete the
old server.
