Tivoli Storage Manager for UNIX Backup-Archive Clients Installation and User's Guide
The Tivoli Storage Manager client must be defined as an application to
HACMP to participate in failover processing. See HACMP for AIX
4.4.1 Installation Guide, SC23-4278, for detailed
instructions on how to perform this procedure. Following is a summary
of this procedure:
- Start HACMP for AIX system management with the following command:
smit hacmp
- Select Cluster Configuration, Cluster Resources,
Define Application Servers, and Add an Application
Server.
- Enter the following field values:
- Server Name
- Enter an ASCII text string that identifies the server. You use this
name to refer to the application server when you define it as a resource
during node configuration. The server name can include alphabetic and
numeric characters and underscores. Use no more than 31
characters.
- Start Script
- Enter the full path name of the script that starts the server. This
script is called by the cluster event scripts and must reside on a local
disk. This script must be in the same location on each cluster node
that might start the server. The start script is used in the following
cases:
- when HACMP is started and resource groups are activated
- when a failover occurs and the resource group is started on another node
- when fallback occurs (a failed node re-enters the cluster) and the
resource group is transferred back to the node re-entering the cluster.
A sample start script (StartClusterTsmClient.sh.smp) is
provided in the /usr/tivoli/tsm/client/ba/bin directory.
- Stop Script
- Enter the full path name of the script that stops the server. This
script is called by the cluster event scripts and must reside on a local
disk. This script must be in the same location on each cluster node
that might stop the server. The stop script is used in the following
cases:
- when HACMP is stopped
- when a failover occurs due to a component failure in a resource group, the
other members are stopped so that the entire group can be restarted on the
target node in the failover
- when a fallback occurs and the resource group is stopped on the node
currently hosting it to allow transfer back to the node re-entering the
cluster.
A sample stop script (StopClusterTsmClient.sh.smp) is
provided in the /usr/tivoli/tsm/client/ba/bin directory.
- Press Enter to add your information to the HACMP for AIX.
- Press F10 after the command completes to exit smit and return
to the command line. Press F3 to perform other configuration
tasks.
The Tivoli Storage Manager client must be in a resource group with a
cascading or rotating takeover relationship. The
client does not support a concurrent access resource group. See
HACMP for AIX 4.4.1 Planning Guide, SC23-4277, for
additional information regarding HACMP topology and strategy.
