HACMP stop script example

A stop script that operates in an HACMP™ environment is illustrated.

Depending on the installation environment, the sample stop script might have to ensure that any backup or restore operation in progress can be stopped.

The stop script is used in the following situations:

HACMP is stopped.
A failover occurs because of a failure of one component of the resource groups. The other members are stopped so that the entire group can be restarted on the target node in the failover.
A fallback occurs and the resource group is stopped on the node currently hosting it to allow transfer back to the node by entering the cluster again.

The stop script is called by HACMP with the root user ID.

Note: This script is not in its final form. It is to be considered pseudo code that indicates the functions it processes.
