fc card down, need to access vg..

[Jonathan Caplette_1]

Hi guys,

I've an FC card that is in AWAITING_LINK_UP state, and the SAN team here don't wanna seems to do something...

Here my problem, I need to mount some filesystems that are configured in a VG (inactive) and the disk (SAN) in that VG (i don't know why) are using only one path, and that path is refering to my FC card. I've an alternate link that should have been configured in that VG, but for a reason i'm ignoring they're not configured in the VG..

Right now the VG is inactive, I can't acces the disks.

My question is there anyway I can retreive acces to those disks to mount the filesystems??
I wanna access the alternate link of the disks I lost...

"AWAITING_LINK_UP" ... says all.
Check switch, cable ... to get the link up.

Run

vgscan -p -v to get the alternate link, add it with
vgextend ...

Shalom,

If you have another HBA card that is linked to the SAN you can.

But there is no way to access disk on the SAN with the FC card in that state. None at all.

Torten: I can't extend the VG, it is inactive, I cannot activate it cause it have been created with only one access to the disks, and that access passthrough my fc card that is down...

[Torsten. · Accepted solution]

Lesson learned about redundancy now?
;-)

Consider this:

- remove the appropriate entry from /etc/fstab
- import the (new) VG using the alternate link
(use vgscan -v -p)
- mount it
- fix it when the link is up again

Torsten:

Thanks it worked fine!! I created a new vg and imported the mapfiles of the old VG...

Hehe... for the redundancy I always create the vg with is Alt link before creating any LVM structure in it... This box is not mine, i'm replacing the regular sysadmin...

Thanks again!
