134 Adding and removing cluster nodes
Removing a node from a cluster
To remove or switch service groups from the departing node
1 Switch failover service groups from the departing node. You can switch grp3
from node saturn to node nebula.
# hagrp -switch grp3 -to nebula
2 Check for any dependencies involving any service groups that run on the
departing node; for example, grp4 runs only on the departing node.
# hagrp -dep
3 If the service group on the departing node requires other service groups—if
it is a parent to service groups on other nodes—unlink the service groups.
# haconf -makerw
# hagrp -unlink grp4 grp1
These commands enable you to edit the configuration and to remove the
requirement grp4 has for grp1.
4 Stop VCS on the departing node:
# hastop -sys saturn
5 Check the status again. The state of the departing node should be EXITED.
Make sure that any service group that you want to fail over is online on other
nodes.
