Hi,

To check whether the volume group is active or not, use 'vgdisplay ' :

# vgdisplay /dev/vgXX

If the vg is not active, the output will show to you that the vg is not active.

To activate / de-activate, use 'vgchange' command.

To activate :
# vgchange -a y /dev/vgXX

To de-activate :
# vgchange -a n /dev/vgXX

For more detail, check manpage of vgchange :
# man vgchange

Hope this information can help you.

Cheers,
AW

vgdisplay vg_name_here

if it is active, you will see the details of the volume group. if it is not active, you will see the message sayin that vg was not activated yet.

to activate a volume group, there are different options for different types of vg's

if vg belongs to a single system (most common)

vgchange -a y vg_name_here

activates the volume group

if this was a volume group used and controlled by a cluster, activation must be done in exclusive mode if it needs to be done outside the cluster control, as follows:

vgchange -a e vg_name_here

if this is a shared volume group but not belonging to a cluster (I don't know any examples why it gets configured that way) it gets activated as follows:

vgchange -a s vg_name_here

To deactivate a volume group, regardles of how it got activated (any of the above)

vgchange -a n vg_name_here

To check status of VG then,

# vgdisplay /dev/vgxx | grep -i status

To activate then,

# vgchange -a /dev/vgxx

See vgchange man page and examples available there.
