Shalom,

Assuming you did not over-write part of the data, the command you are looking for is vgimport.

Hello,

you can try to import the volume group (vgimport command). You need a list of physical device files that were comprising the volume group before (see manual page for vgimport).

You need to create the volume group control file manually prior to importing it, something like this:

# mkdir /dev/vg01
# mknod /dev/vg01/group c 64 0x020000

then you can run vgimport.

Hi Avizen,

It is not surprise that 11.11 could not see the VG01. Because 11.11 does not know anything about VG01 since you have installed freashly. You should have exported the VG01 with map file and import it after 11.11 installation.

Still you can import the VG01 to 11.11. You should knows the disks part of VG01.

Try these steps.

#mkdir /dev/vg01
#mknod /dev/vg01/group c 64 0x010000

#vgimport -v /dev/vg01 /dev/dsk/c0t1d0 /dev/dsk/c0t3d0 ...
(specify all the disks which was part of VG01)

#vgchange -a y vg01

Then you can create mount points and mount it.
