Volume group varyon problems

Use varyoffvg command for the volume group at all nodes to correct varyonvg issues at the volume group layer.

If an NSD backed by an underlying logical volume will not come online to a node, it may be due to varyonvg problems at the volume group layer. Issue the varyoffvg command for the volume group at all nodes and restart GPFS. On startup, GPFS will varyon any underlying volume groups in proper sequence.
