ServiceGuard cluster & volume group failover

ServiceGuard cluster & volume group failover
I have a 2-node ServiceGuard cluster. One of the cluster packages has a volume group assigned to it. When I fail the package over to the other node, the volume group does not come up automatically on the other node.
I have to manually do a "vgchange -a y vgname" on the node before the package will come up. If I fail it back to the original node, I once again have to issue the vgchange command manually before the package will start.
What am I missing? I see some cluster related options in the vgchange man page but I don't understand if/how/when to use them.
What do I need to do for this volume group to automatically come up when I fail the package over?
TIA!

Hey! I'm running a HP ServiceGuard cluster with three nodes. One of the packages was moved (not by me) from one node to another a few weeks ago.
