Configuring the HSM client to connect to a secondary Tivoli Storage Manager server

If the primary Tivoli® Storage Manager server for the HSM for Windows client is unavailable, you can manually configure the HSM for Windows client to connect to a secondary server. You can recall files from the secondary Tivoli Storage Manager server but cannot migrate files to the secondary server.

Before you begin

The primary Tivoli Storage Manager server for the HSM for Windows client must be one that replicates client node data.

About this task

The Tivoli Storage Manager server that the HSM for Windows client connects to during normal production processes is called the primary server. When the primary server is set up for node replication, the data for client nodes can be replicated to the secondary server.

The backup-archive client can automatically fail over to the secondary server when it is configured for failover.

The HSM for Windows client, however, does not automatically fail over to the secondary server. You must manually configure the dsm.opt file to connect to the secondary server. Any secondary server information in the replservername stanza, the myreplicationserver option, and the myprimaryserver option is ignored by the HSM for Windows client.

You can complete some tasks when connected to the secondary server:

You can recall and retrieve migrated files from the secondary server by using the HSM for Windows client.
You can restore a stub file by using the backup-archive client.
You must not reconcile the file system with the secondary server.
You must not migrate files to the secondary server.

Procedure

To configure the HSM for Windows client to connect to the secondary server complete the following step:

Edit the dsm.opt file to specify information about the secondary server. The following stanza is an example of a secondary server stanza:

   COMMmethod                  TCPip
   TCPPort                     1500
   TCPServeraddress            lifeboat.almaden.ibm.com
   Passwordaccess              generate

What to do next

After you complete this steps, restart the HSM for Windows client.

You can complete some tasks when connected to the secondary Tivoli Storage Manager server:

You can recall and retrieve migrated files from the secondary server by using the HSM client.
You can restore a stub file using the backup-archive client.
You must not reconcile the file system with the secondary server.
You must not migrate files to the secondary server.

Connect to the primary Tivoli Storage Manager server as soon as it becomes available.
