Responding to Cluster Events
Serviceguard does not require much ongoing system administration
intervention. As long as there are no failures, your cluster will be
monitored and protected. In the event of a failure, those packages that
you have designated to be transferred to another node will be transferred
automatically. Your ongoing responsibility as the system administrator
will be to monitor the cluster and determine if a transfer of package has
occurred. If a transfer has occurred, you have to determine the cause and
take corrective actions.
The typical corrective actions to take in the event of a transfer of package
include:
• Determining when a transfer has occurred.
• Determining the cause of a transfer.
• Repairing any hardware failures.
• Correcting any software problems.
• Restarting nodes.
• Transferring packages back to their original nodes.
• Enabling package switching.
