If desired, you can also manually relocate and remove cluster members by using the clusvcadm

commmand at a shell prompt.

1. To prevent service downtime, any services running on the member to be removed must be

relocated to another node on the cluster by running the following command:

clusvcadm -r cluster_service_name -m cluster_node_name

Where cluster_service_name is the name of the service to be relocated and

cluster_member_name is the name of the member to which the service will be relocated.

2. Stop the cluster software on the node to be removed by running the following commands at

that node in this order:

a. service rgmanager stop

b. service gfs stop and/or service gfs2 stop, if you are using gfs, gfs2 or

both

c. umount -a -t gfs and/or umount -a -t gfs2, if you are using either (or both)

in conjunction with rgmanager

d. service clvmd stop, if CLVM has been used to create clustered volumes

e. service cman stop remove

3. To ensure that the removed member does not rejoin the cluster after it reboots, run the

following set of commands:

chkconfig cman off

chkconfig rgmanager off

chkconfig clvmd off

chkconfig gfs off

chkconfig gfs2 off
