Not able to activate vg

[Rupesh_13]

I am not able to activate VG. vgchange -a y vg_swap gives followsing error
vgchange: Warning: Couldn't attach to the volume group physical volume "/dev/dsk/c80t13d0":
Cross-device link
vgchange: Warning: couldn't query physical volume "/dev/dsk/c80t13d0":
The specified path does not correspond to physical volume attached to
this volume group
vgchange: Warning: couldn't query all of the physical volumes.
vgchange: Couldn't activate volume group "vg_swap":
Quorum not present, or some physical volume(s) are missing.


In ioscan I am able to see the disk and diskinfo is showing the information about the disk.

Urgent help on this required.

Thanks in advance.

Can you check #dmesg and syslog for more details ?

Hi,

This error means that one of the disk belonging to this VG is missing or has been moved.

What is the output of

#strings /etc/lvmtab

Also try to activating the VG without quorum check

#vgchange -a y -q n /dev/vg_swap

HTH,
Devender

The first thing I do when I see something like this is to check if the disk reflects the correct vgid info.

Get the c-t-d- number of one disk that you still show as part of the vg and run:

echo "0x2008?4D" | adb /dev/dsk/

Take a look at the fifth (last) column and note it's value.
Now run the same command using the problem disk and see what value it says...
If it's different, can you identify what vg it goes to ?
Then I'd have a couple other questions, cause this error may simply be one side of a two sided issue....:

Do you use BCV's ??
What was the last VG you set up, or change to any VG you did ?? Is everything still working properly there ? Have your cross checked to ensure you didn't erroneously use that disk on something new ??

Once you know exactly where your at, maybe we can help get you back where you belong.

Hi Rita ,

What does the columns represent ?

echo "0x2008?4D" | adb /dev/dsk/c2t6d0
2008: 632309393 1112792185 632309393 1112709082


Thx,

One of the disk of the vg was failed.

I replaced it and now the system is ok.

Thanks for the help and suggestions

Warm regards
