Renaming a Veritas cluster online service group

This article provides 6 quick steps to allow you to rename on online service group under VCS cluster.

1. Freeze the service group

   # haconf -makerw
   # hagrp -freeze <SG_name> -sys <system_name> -persistent
   # haconf -dump -makero

   where: <SG_name> - is the name of the service group that you wish to rename <system_name> - is the cluster node where the service group is currently online.

   For example if we are renaming service group SG03 on cluster node vcsdevnod03, we would perform:

   # hagrp -freeze SG03 -sys vcsdevnod03 -persistent

2. Stop HAD but keep service groups online

   # hastop -all -force

3. Change the name of the service group and save the file

   # cd /etc/VRTSvcs/conf/config
   # cp main.cf main.cf.orig
   # vi main.cf

4. Start VCS on the modified main.cf node

   # hastart

5. Run hastart on all remaining nodes so that they do the REMOTE_BUILD and main.cf with the new service group name is copied over to all the remaining nodes
6. Unfreeze the service group

   # haconf -makerw
   # hagrp -unfreeze <SG_name> -sys <system_name> -persistent
   # haconf -dump -makero
