HACMP concurrent Vg synchronizing

On a HACMP/PowerHA cluster, with concurrent VG, if a filesystem is created outside HACMP, the cluster is "out of sync"... if we do a lsvg -l on both nodes, some mount point will be N/A on the remote node.

The online way to resynchronize is :

on the passive node :
varyoffvg VGname

on the active node :
/usr/es/sin/cluster/sbin/cl_updatevg -cspoc -g ResourceGroupName VGname
or via Cspoc menu -> HACMP Logical Volume Management -> synchronize a Shared VG definition

On the passive node :
varyonvg -n -c -P VGname
