Mirror disk path changed
One of our server have internal boot disk , which was mirrored with a lun from XP san storage. There was some activities done on SAN storage.
After this activity, the device path of mirrored Xp lun got changed & mirroring got broken. I can see the mirrored disk in ioscan output & vgdisplay vg00 shows error saying that mirror disk not present. Now i am not able to unmirror this disk & mirror it back with newer device path.
Is it possible or restore from ignite only way to rollback ???
THanks in advance

Re: Mirror disk path changed
Consider to unmirror the disk, remove it from the VG, then create the mirror again with the new device path.
Hope this helps!
Regards
Torsten.

Re: Mirror disk path changed
due to physical volume unavailabe you need pvkey to reduce the mirror
lvreduce it using pvkey
lvdisplay -v -k lvol wil give you the pvkey.
lvreduce -m 0 -k lvol
after do it for all lvs.
Reduce the mirror
vgreduce -f vgname
after that follow the normal root mirroring procedure.
