7.8.8.1 Changes that Will Trigger Warnings
Changes to the following will trigger warnings, giving you a chance to cancel, if the change would
cause the package to fail.
NOTE: You will not be able to cancel if you use cmapplyconf -f.
• Package nodes
• Package dependencies
• Package weights (and also node capacity, defined in the cluster configuration file)
• Package priority
• auto_run
• failback_policy
7.9 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.
