Hi Again,

PLease post the result of:
# vgchange -a y -q n vg02

If above works, post:
# vgdisplay -v vg02

Else:
#strings /etc/lvmtab
to see which disks were present in vg02. NOw see if they are "claimed" in "ioscan -fnC disk".

If yes..run:
#vgscan -pav
(This is only preview mode. No changes will be made to system.) And see which disks comes up under vg00.
If it is different from those in /etc/lvmtab, take backup of original lvmtab and run:

#vgscan -av
to recreate lvmtab (only after taking backup of lvmtab).
