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

1. 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

2. 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

3. Run the following command from the cluster renamed to VCSPriCluster2:

   hagrp -online ClusterService -any
