HP-UX Logical Volume Manager and MirrorDisk/UX Release Notes (March 2010 Update release)

Sharing volume groups in an HP Serviceguard cluster
To share a volume group in an HP Serviceguard cluster where the cluster nodes have different
versions of the LVM product installed, use the following guidelines:
• To share a version 2.1 volume group, you must install the HP-UX 11i v3 September 2008
release or above on all the cluster nodes.
• To share a 2.2 volume group, you must install the HP-UX 11i v3 March 2010 release or above
on all the cluster nodes.
• To use the Multi Node Online Reconfiguration (MORE) feature, you must install the HP-UX
11i v3 September 2009 release or above on all nodes of the cluster. Further, you can use
MORE only on version 2.1 or above volume groups.
NOTE: MORE is not working in a cluster with both HP-UX 11i v3 September 2009 and
HP-UX 11i v3 March 2010 nodes. During a rolling update from HP-UX 11i v3 September
2009 to HP-UX 11i v3 March 2010, you cannot use MORE on the shared volume group.
