HELP. My disks have new names and my VG won't activate

[Ray Humpage]

I lost an HBA and all my disks showed as NO_HW.
The other HBA didnt take over like they should have. When I rebooted the other HBA did take over and shows all disks on both FC10 arrays. The disks have new names though and my VG won't activate.

nmhptprd(/)# vgchange -a y /dev/vg08

Just recreate your lvmtab:

mv /etc/lvmtab /etc/lvmtab.sav
vgscan -a

I am thinking a vgcan and a possible vgimport.

vgscan to recreate /etc/lvmtab after rename.
If vgimport is needed vgscan will advise.

Cheers.

HP engineer just showed up with the replacement part. I currently have the box down and am replacing the HBA. Will see what DEV path names come up after it's replaced. Any luck that I will get my original names once the HBA is replaced?

If not I will then try the vgscan. Check back with you in about an hour. Thanks for the advice so far.

u have to run vgscan command query with any volume group it will recreate it
