Using vgcfgbackup to backup all Volume Groups

dictum9 — Wed, 04 Oct 2006 16:38:34 GMT

I understand that vgcfgbackup takes a VG as an argument, but I would like to backup all Volume Groups, is there a script available for it?

If you have VG with different name that vgXX you will miss it.

better use :

#!/usr/bin/ksh
vgdisplay | grep -i "VG Name" > vgs.txt
cat vgs.txt | while read n1 n2 n3
do
vgcfgbackup $n3
done
rm vgs.txt

cheers,

In case your VG name is different than vgXX then use:

# bdf | awk -F/ '$0~"^/dev"{print $3}' | uniq | xargs -n1 vgcfgbackup

One thing that you may not have grasped is that vgcfgbackup does not, in fact, backup a volume group -- or more accurately the data IN a VG but rather, it backs up the VG meta data --- the data ABOUT the VG.

for arg in $(/etc/vgdisplay |grep "VG Name")
do
case $arg in
*dev*) /etc/vgcfgbackup $arg;;
*) continue;;
esac
done

I have been using bdf for a while and it's working good.
But how do I take vgcfgbackup of a VG that has not been activated? (Case in point, a BCV volume)
vgcfgbackup returns with an error.

The VG needs to be activated, even if for a short time

How can I find out if a VG is activated or not?

Other than running vgcfgbackup and having it fail.

Hi:

> How can I find out if a VG is activated or not?

Given that you know the name of the VG, its *absence* in the output of 'vgdisplay' would indicate that is is *not* activated.

I got a list of active VGs and a list of all VG's, I can find out the delta.

ll -d /dev/vg*

gives me the list of all VGs, active and not actived.

... but if a name of a VG is not of the form vg*, this will fail as well.
You could however look for the major number of all device files in /dev ...

My main issue right now is figuring out if a node is an active node in a SG cluster so I can active the non-activated VG for taking the vgcfgbackup.

cmviewcl gives too much output.

vgdisplay will give you the information you need in regards to if a volume group is active or not.
just issue vgdisplay | more and this will list all active volume groups and will state if a volume group is not activated on that server. it lists all volume groups, even the ones controlled by Serviceguard.
