Error: Unable to determine a unique identifier for physical volume

If you get this errors, check your lvm info is in sync in all your cluster nodes, if not vgexport/import, and also look at:

cmquerycl searches all specified nodes for cluster configuration and
Logical Volume Manager (LVM) information.

So if the volume still exist in the /etc/lvmtab it will complain about it, because it has no cluster identifier on it (vgchange -c n).

Remove it from the LVM configuration and try again.

Two ideas:
1) Have you run the "vgchange -c n" from both nodes in the cluster ?

2) Have you physically removed the disks from the system ? If you have removed the disks physically from the system and they are still in the /etc/lvmtab on either system, this can cause the error you are seeing. If they have been physically removed from the system, you need to vgexport the volume group from /etc/lvmtab otherwise SG will attempt to read them again.
