Varyoffvg in AIX

# varyoffvg <Volume_Group> : Commad to deactivate a volume group.

When a volume group is not active the logical volume or the physical volume on the volume group could not be listed.

To overcome this issue, we can apply "-s" flag when we varyoff of the volume group, this flag is for maintenance mode. This would ensure we can still view the attributes of a volume group even though its deactivated.

# varyoffvg -s vgp
# lsvg -l vgp
vgp:
LV NAME             TYPE       LPs   PPs   PVs LV STATE      MOUNT POINT
