No access to vg drive bay
Perhaps someone can help me.
On a HP-UX B11.11, after a reboot, the 4 non-system disk group do not mount at all.
I do not know what it happened but I think the address of these disks is no longer good

Re: No access to vg drive bay
mv /etc/lvmtab /etc/lvmtab.orig
vgscan -av
this will recreate your lvmtab after checking all the available physical volumes.
Please post the result?

Re: No access to vg drive bay
yes before reboot, i had a failed disk on vg00 (c1t2d0). I replace (hot-swap) it but it didn't resync.
I think i need to reboot and boom !
now i turn around the solution because vgscan remove the vg00 :
vgscan: The physical volume "/dev/dsk/c2t2d0" is already recorded in the "/etc/l
vmtab" file.
vgscan: has no correspoding valid raw device file under /dev/rdsk.
Verification of unique LVM disk id on each disk in the volume group
/dev/vg00 failed.
/dev/vg02
/dev/dsk/c6t2d0
/dev/dsk/c7t2d0
/dev/vg03
/dev/dsk/c6t4d0
/dev/dsk/c7t4d0
/dev/vg04
/dev/dsk/c6t6d0
/dev/dsk/c7t6d0
vgscan: has no correspoding valid raw device file under /dev/rdsk.
Verification of unique LVM disk id on each disk in the volume group
/dev/vg01 failed.
Scan of Physical Volumes Complete.
And the result lvmtab :
strings lvmtab
/dev/vg02
/dev/dsk/c6t2d0
/dev/dsk/c7t2d0
/dev/vg03
/dev/dsk/c6t4d0
/dev/dsk/c7t4d0
/dev/vg04
/dev/dsk/c6t6d0
/dev/dsk/c7t6d0
since, i manualy vgreduce vg00, but vgscan give the same result.
thanks

Re: No access to vg drive bay
But check the following.
your ioscan showing only 8 disks.
But orig lvmtab showing 10 disks.So veryfy all the disks are available.
Your vg00 was mirrored right?or it was a hardware mirror?
If it was vg00 mirroring Have you follow the online disk replacement procedure?
Should run vgcfgrestore
and then vgsync.Then

Re: No access to vg drive bay
Yes there are missing disks : one system disk that i had unplug and another for which I have no explanation.
All the disk on this machine are logical mirroring.
In a rush, unfortunately I do not follow procedure.
After visual verify and replug all the disk :

2 questions :
- why the vgscan removes the vg00 and vg01 ?
- why my references discs have changed ? old c5t0d0 becomes c7t0d0 ?
