To reconfigure VCS on existing nodes

1. On Node A, create the files /etc/llttab, /etc/llthosts, and /etc/gabtab. Use the files that are created on Node B as a guide, customizing the /etc/llttab for Node A.

2. Start LLT on Node A.

   # /sbin/init.d/llt start

3. Start GAB on Node A.

   # /sbin/init.d/gab start

4. Check the membership of the cluster.

   # gabconfig -a

5. Start VCS on Node A.

   # hastart

6. Make the VCS configuration writable.

   # haconf -makerw

7. Add Node B to the cluster.

   # hasys -add sysB

8. Add Node B to the system list of each service group.

   • List the service groups.

     # hagrp -list

   • For each service group that is listed, add the node.

     # hagrp -modify group SystemList -add sysB 1
