Check cluster consistency


In a clustered installation of HPOM it is necessary to keep the installation consistent on all nodes, regardless of which of the physical cluster nodes it is currently running on. A consistent installation means that all nodes have the same SPIs and HPOM patches installed. A clustered installation also requires a consistent configuration of HPOM on all cluster nodes.
Caution CAUTION:
As long as a cluster inconsistency is unresolved, HPOM cannot start or failover to the inconsistent cluster nodes. This could lead to unexpected down times of the management server.

Using the console tool Cluster Check Report, you can evaluate the current consistency status of the clustered HPOM installation. The tool also enforces cluster consistency. See the topic Cluster Consistency Enforcement for details.

During the installation of the management server, a self management policy called "VP_SM-ClusterConsistency Check" is deployed to the management serve nodes. This policy checks the cluster once a day and generates a critical message if an inconsistent cluster is discovered. For details about this inconsistency, see the message annotations and instructions.

Consistent configuration is ensured by both storing data in the database and replication registry keys. For details, see Registry Key Replication.
