Registry key replication


As described in the Check Cluster Consistency topic, it is vital for the operation of HPOM in a cluster to have the HPOM installation on all cluster nodes installed and configured consistently.

Because part of the HPOM configuration is stored in the system registry, parts of it will get replicated between the cluster nodes by the OvOW Registry Replication cluster resource, as described in the topic HPOM Cluster Resource Group. Each time this resource goes online on a cluster node, it replaces the registry keys listed below with the ones existing on the last active node. This has two consequences: first, only the currently active node has an up-to-date HPOM registry, and second, it is necessary make changes in these replicated keys on the currently active node. Changes made on other nodes will be lost whenever they become active.

The following list shows the registry keys replicated by the registry replication resource. Each key, with all its values and its subkeys, will be replicated.

Note NOTE:
This list is not a documentation of how these keys are used by HPOM or an encouragement to change these. Refer to other parts of the documentation to see whether changing these keys is supported or not.
