Stopping a cluster administrative domain

Cluster administrative domains provide environment resiliency for resources within an IBM® i high-availability solution. You might need to stop a cluster administrative domain to temporarily end synchronization of monitored resources.

A cluster administrative domain becomes inactive when it is stopped. While the cluster administrative domain is inactive, all of the monitored resources are considered to be inconsistent because changes to them are not being synchronized. Although changes to monitored resources continue to be tracked, the global value is not changed and changes are not propagated to the rest of the administrative domain. Any changes that are made to any monitored resource while the cluster administrative domain is inactive are synchronized across all active nodes when the cluster administrative domain is restarted.

Note: The cluster administrative domain and its associated exit program are IBM-supplied objects. They should not be changed using the QcstChangeClusterResourceGroup API or the CHGCRG command. Making these changes will cause unpredictable results.
