Changing the Cluster Name
This section describes how to change the ClusterName in a global cluster configuration. The instructions describe how to rename VCSPriCluster to VCSPriCluster2 in a two-cluster configuration, comprising clusters VCSPriCluster and VCSSecCluster configured with the global group AppGroup.
Before changing the cluster name, make sure the cluster is not part of any ClusterList, in the wide-area Heartbeat agent and in global service groups.
To change the name of a cluster

Run the following commands from cluster VCSPriCluster:
# hagrp -offline ClusterService -any
# hagrp -modify AppGroup ClusterList -delete VCSPriCluster
# haclus -modify ClusterName VCSPriCluster2
# hagrp -modify AppGroup ClusterList -add VCSPriCluster2 0
-
Run the following commands from cluster VCSSecCluster:
# hagrp -offline ClusterService -any
# hagrp -modify appgrp ClusterList -delete VCSPriCluster
# hahb -modify Icmp ClusterList -delete VCSPriCluster
# haclus -delete VCSPriCluster
# haclus -add VCSPriCluster2 your_ip_address
# hahb -modify Icmp ClusterList -add VCSPriCluster2
# hahb -modify Icmp Arguments your_ip_address -clus
VCSPriCluster2
# hagrp -modify AppGroup ClusterList -add VCSPriCluster2 0
# hagrp -online ClusterService -any
-
