vgscan

[Daniel Caçador]

Hi!

Look this message after I execute the vgscan -v:

vgscan: couldn't access the list of physical volumes for volume group "/dev/vg00".

The volume group /dev/vg00/group was not matched any Physical volumes complete.

Thank's!!!

Hi Daniel,

can you post the output of

ll /dev/vg00/group

Does vgdisplay on vg00 get error messages as well?
Have you backupped /etc/lvmtab before to launch vgscan?

Regards,
Fabio

Daniel,
why did run the vgscan command? First paragraph of man vgscan says to "in the event of a catastrophic error".

Have you got a backup of your /etc/lvmtab.
Seems the system thinks you have a vg00 without actual physical disks!

Did you have a diskcrash?

Hi,

what is the content of lvmtab now?

Try to mv the /etc/lvmtab and run vgscan

Regards,

Siva.

Do check for /dev/lvmconf/vg00.conf and if some older files and also decide on which disks should be in vg00.
Make sure those are the disks which should belong to VG00.. And then take other steps..

[Daniel Caçador]

Yes, have the files, how the others steps?

[Prashant Zanwar_4]

You can list the disks which were in use like following..

vgcfgrestore -n vg_staging_tmp -l
Volume Group Configuration information in "/etc/lvmconf/vg_staging_tmp.conf"
VG Name /dev/vg_staging_tmp
---- Physical volumes : 4 ----
/dev/rdsk/c22t9d4 (Non-bootable)
/dev/rdsk/c23t9d4 (Non-bootable)
/dev/rdsk/c22t9d5 (Non-bootable)
/dev/rdsk/c23t9d5 (Non-bootable)

You can also use same command like below:

vgcfgrestore -f /etc/lvmconf/vg_staging_tmp.conf.old -l
Volume Group Configuration information in "/etc/lvmconf/vg_staging_tmp.conf.old"
VG Name /dev/vg_staging_tmp
---- Physical volumes : 4 ----
/dev/rdsk/c22t9d4 (Non-bootable)
/dev/rdsk/c23t9d4 (Non-bootable)
/dev/rdsk/c22t9d5 (Non-bootable)
/dev/rdsk/c23t9d5 (Non-bootable)


Decide with your best judgement what disks were in use for VG00..

Then check lvmtab, if it is messed up..


Recreate lvmtab & check after that..

Whatever you do have all config backup first..

/etc/lvmconf/vg00* (backup to safe place)
/etc/lvmtab - back up

Gud luck
Prashant
