To prepare to remove a node from a cluster

1. Take your application service groups offline if they are under Veritas Cluster Server (VCS) control on the node you want to remove.

   # hagrp -offline app_group -sys sys5

2. Stop the applications that use Veritas File System (VxFS) or Cluster File System (CFS) mount points and are not configured under VCS. Use native application commands to stop the applications.

To remove a node from a cluster

1. Unmount the VxFS/CFS file systems that are not configured under VCS.

   # umount mount_point

2. Stop VCS on the node:

   # hastop -local

3. Uninstall SFCFSHA from the node using the SFCFSHA installer.

   # cd /opt/VRTS/install

   # ./uninstallsfcfsha sys5

   The installer stops all SFCFSHA processes and uninstalls the SFCFSHA packages.

4. Modify the VCS configuration files on the existing nodes to remove references to the deleted node.

   See Modifying the VCS configuration files on existing nodes.

5. Modify the Cluster Volume Manager (CVM) configuration on the existing nodes to remove references to the deleted node.
