Can you remove a volgroup from hacmp with ha running

Can you remove a volume group from hacmp with it running? Then sync the systems and remove the volume group. from both systems??

If the vg is configured as a resource in any cluster resource group then you can't remove it from the cluster without prior unconfiguring the vg from the RG.

I guess if there are any open shared LV/FS then removing the VG from a cluster RG will fail. If all shared LV/FS belonging to the VG are closed that I thing you can unconfigure/remove the VG from your RGs (of course with RG synchronization after that).

The CSPOC menu in HACMP 4.5 for Shared Volume Groups have below options only, so after the VG have been removed from cluster RGs, you would have to remove VG manually from all cluster nodes.

Create a Shared Volume Group
Set Characteristics of a Shared Volume Group
Import a Shared Volume Group
Mirror a Shared Volume Group
Unmirror a Shared Volume Group

In hacmp 5.1/5.2 there is an option for removing shared VG from a cluster:

List All Shared Logical Volumes by Volume Group
Add a Shared Logical Volume
Set Characteristics of a Shared Logical Volume
Show Characteristics of a Shared Logical Volume
Change a Shared Logical Volume
Remove a Shared Logical Volume
