rp3440 connected to msa30 cannot activate vg
Good morning: I have a customer who has problems on activiting a volume group with 2 146 GB mirrored disks just after we power off and bring up a rp3440 server connected to a msa30 where the disks are placed. I have found an article here that talks about missing disks on msa30 apparently as not attached to the controller after reboot.
http://h30499.www3.hp.com/t5/LVM-and-VxVM/missing-vg/m-p/5013237#M43458
I think this was a little different from the problem we had. In the problem presented
in the forum the SA was eventually able to activate his volume groups. Then he ran
fsck and was able to mount his filesystems. Our problem is different from this in that
we could not activate the volume group by any means. We could see the disks in the
array with sautil, but the volume group information seemed to be corrupted and could
not be restored/rebuilt.
I put info attached here, if anyone has an idea what could be the problem it would be helpful
Thanks and regards
I would want you to take a look at the following link http://h30499.www3.hp.com/t5/LVM-and-VxVM/missing-vg/m-p/5013237#M43458, in case when you troubleshooted you encountered similar behaviour

Re: rp3440 connected to msa30 cannot activate vg
The RAID remains in FAILED status.
You need to run
# sautil /dev/ciss4 accept _media _xchg 1
to enable the RAID again, but the disks are empty now.
So you need to get rid of the old VG information stored in the system (e.g. vgexport); then pvcreate, vgcreate, lvcreate etc ...
Hope this helps!

Torsten.
