VCS: Add/Remove Node From Cluster

Removing VCS Host:

• Remove system from /etc/llthosts. Rename /etc/rc2.d scripts.
• hastop -local
• From another node in cluster run the hagrp -modify commands. Once node no longer exists in service groups, you can finally remove it with hasys.
  

hagrp -modify casper SystemList -delete denitdb03
hasys -delete denitdb03

Adding VCS Host:

• Be sure to update /etc/llthosts with the correct ID, in this case 3.
• Use the main.cmd to get the syntax correct for an additional system.
