6.9 Uninstalling CSM

If you want to completely remove CSM from all the nodes in your cluster and the management node, use the uninstallms command:

 # uninstallms -u 

This will:

  • Remove the CSM code from the cluster nodes by running rmnode -u -N AllNodes.

  • Uninstall CSM rpms from the management node.

  • Delete the CSM logs from the management node.

The uninstallms -u command will not remove the CSM configuration from /etc/opt/csm, the CD images from /csminstall, or the csm.core fileset from the management node. These must all be uninstalled manually, as shown in Example 6-38.

Example 6-38: Uninstalling CSM
