Disk removed accidently and back up path is unavailable

[UnixT]

Hello Gurus,

I removed a disk from a vg using vgreduce but the alternate path for that disk was unavailable by that time which was not noticed. So the VG went down and I need the original removed disk path to be added for accessing the vg. I tried with vgcfgrestore to the removed path but could not succeed. We do have all the configuration backup avail with us. Can any one help me on this to come out...The details are below..

HP UX 11.23
Primary path : c2t2d2 (which was available and removed) -- This is to be readded to the VG
Alternate path : c3t3d3 (not available at all)
VGName : VGQA_SA

Regards.....

1. vgcfgrestore VGQA_SA /dev/dsk/c2t2d2
2. vgchange -a y VGQA_SA

a. vgimport VGQA_SA /dev/dsk/c2t2d2
b. vgchange -a y VGQA_SA

Hi

Provide following output:

ll -rt /etc/lvmconf/VGQA_SA.conf*

vgcfgrestore -f /etc/lvmconf/VGQA_SA.conf(latest file) -l

vgcfgrestore -n /dev/VGQA_SA -l

Also:

You list the things with commands you did till now!!!

Regds,
Deepak

If you have vgreduced c2t2d2 from the VG it is also removed from /etc/lvmtab and the configuration backup.

So vgcfgrestpre can't help you, you need to vgextend the disk again.

Do vgextend VGNAME /dev/dsk/c2t2d2 Again
