Operating Systems AIX Adding existing VG to powerHA Resource group Post 302600101 by funksen on Monday 20th of February 2012 05:40:15 AM
Old 02-20-2012
that's how I killed a tsm-Cluster Smilie, added one vg to a resource group that already had about 5 vgs, after a sync the resource group reconfigured itself, forcing unmount and mount

but you can safely add a new resource group to the cluster while it is running

don't know if this behavior has changed in newer power ha (6/7) releases
