As in most things, removing the configuration is much easier than setting it 
up. To remove a cluster, do the following:

#. Halt the cluster::

      cmhaltcl -f

#. Edit the /etc/lvmrc file.

   a. Set the AUTO_VG_ACTIVATE variable to 1
   b. Comment out any modifications to the custom_vg_activate function call.

#. Update the /etc/fstab file to enable automatic filesystem mounting as 
   appropriate.
#. Deactivate exclusive mode bit on all MCSG managed volume groups::

      vgchange -c n ${vg}

#. Remove the MCSG software
