Veritas Storage Foundation 5.1 SP1 Cluster File System Installation Guide (5900-1510, April 2011)

■ Unmounting the File System and Cluster File System file systems not
configured under VCS.
■ Uninstalling SFCFS from the node.
Modifying the VCS configuration files on the existing nodes.
■ Removing the node configuration from the CP server if it is configured.
■ Removing the security credentials from the node if it is part of a secure cluster.
■ Updating the SFDB repository if you use SFDB tools.
The Veritas product installer does not support removing a node. You must remove
a node manually. The example procedures describe how to remove a node from
a cluster with three nodes.
Removing a node from a cluster
Perform the following steps to remove a node from a cluster. The procedure can
be done from any node remaining in the cluster or from a remote host.
To remove a node from a cluster
1
Take your application service groups offline (if under VCS control) on the
node you want to remove.
# hagrp -offline app_group -sys saturn
2
Stop the applications that use VxFS/CFS mount points and are not configured
under VCS. Use native application commands to stop the applications.
3
Stop VCS on the node:
# hastop -local
4
Unmount the VxFS/CFS file systems that are not configured under VCS.
# umount mount_point
