What is vg04?

[Kranti Mahmud]

Hello All,

I have a cluster environment with 2 rx2660 & MSA 1000. In active node, the vg's are vg00, vg01, vg02. But System managment homepage shows another vg, vg04? I wanna know, what it is? Please find the attachement for more clarification?

Check if the VG is listed:

# strings /etc/lvmtab

most likely it belongs to the other node.

Check

# vgdisplay -v vg04

from the other node.

Hi,
Please post this command's output

#vgdisplay -v
#strings /etc/lvmtab
#ll /dev/vg04

Please attach this too:

# ll /etc/lvmconf


BTW, not related to this problem, but may cause other problems:

I think your MSA is presenting the LUNs in a wrong mode (not hpux, but default or windows - please check!)!

this may be another file system or may be package file system structure. anything could be possible.

If you want to know if it is belongs to cluster then check the cluster config ascii file.

or may be it contains file system which system admins doesn't want to activate during boot. for more confirmation check in /etc/fstab

activate the vg04

#vgchange -a y vg04

and check

As said earlier, do the same check from the other node too.

Hi


This is a VG that the /etc/lvmtab shows that.
more than that can u tell about these also doing that on both the nodes.
bdf
vgcfgrestore -l -n /dev/vg04
cat /etc/fstab
swapinfo -tam
for all the package configuration files in /etc/cmsluster//.cntl.log do a grep vg04 for the VG Name so that you can make sure that the VG is activated by some package.

please do all above on both the cluster nodes,that shall help know if that VG is configured in Package and or for swap.
