Tivoli Space Manager for UNIX Using the Hierarchical Storage Management Clients


Set Up Space Management for AIX in an HACMP Environment

Attention: The HACMP environment is valid on AIX JFS file systems only.

The HSM client permits your HSM-managed file system to become a part of a resource group in an HACMP cluster so that if there is a system failure, you can obtain access to your data from another system. To set up space managment in an HACMP environment, each node in a cluster, willing to take over HSM-managed file systems, must specify a server stanza for every TSM server that your file systems use in a cluster that it might want to manage. Place this stanza in your dsm.sys file. You can use a server stanza for more than one file system.

Note:
For more information about the HACMP environment for AIX, see Tivoli Storage Manager for UNIX Installing and Using the Backup-Archive Clients.

Across different nodes, the server stanza must have the following characteristics:

The HSM for HACMP also supports cascading and rotating takeover relationships in the same manner as the backup-archive client. The password handling is the same as that of the HACMP backup-archive client. The dsm.opt file and the dsm.sys file can reside in the standard /usr/tivoli folder, or you can use the DSM_CONFIG environment variable that you set in the start script. However, the behavior must be identical on all nodes.
