High Availability

High availability considerations

Before you upgrade your system to IBM i 7.2, make sure your cluster version is 7. If you have 5770-HAS (IBM PowerHA SystemMirror for i) installed, make sure your HA version is 2.2. The Change Cluster Version (CHGCLUVER) command can be used to adjust the current version of the cluster and the PowerHA product.

Support was added to Cluster administrative domain to monitor owner and authority attributes for all monitor resource entries in cluster version 8. So if a user does not want to monitor owner and authority attributes, then they must list all the attributes they are interested in, instead of coding *ALL.
