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.
Set the AUTO_VG_ACTIVATE variable to 1
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
