I am trying to activate my volume and i am getting and error. When i try to vhchange -a y /dev/vg02 i get "unknown error". The disks for this volume group are good and all the other volume groups are fine. What could be wrong

It seams that the control file of the volume group has been corruped. You have to export/import the volume group.

# vgexport vg02

# mkdir /dev/vg02
# mknod /dev/vg02/group c 64 0x020000
# vgimport vg02 /dev/dsk/... /dev/dsk/c...

# vgchange -a y vg02

That should work ;-)

Armin

Check the output from this command and see if the information is correct and up to date.

strings /etc/lvmtab

mknod /dev/vg02/group c 64 0x020000

could easily be a source of error, vg02 does not have to be minor 0x020000.

ll /dev/*/group

and choose a unique identifier for the v group.
