Vgimport/export on AutoRAID 12H

[Maarten van Maanen]

I've done vgexport on vgimport on the systems disk of our K370 without much problems. Concerning this I have two questions.
1.) Does vgexport/vgexport work on a 12H AutoRAID system as well? And even if the LUN's have been deleted? I have no room on our 12H to try this myself at the moment.
2.)Is there a way to change the VG-name during vgimport? Say I used to have a vg02 but want to change that to a vg03.

vgimport and vgexport work just the same for RAID volumes as for simple disks.

It won't work if you delete the LUN's though, that's equivalent to swapping a disk and expecting the new one to contain the same data as the old one.

Yes you can change the volume group name. vgexport/import is the recommended way for doing this.

To rename vg02 to vg03 you need to create a directory and a group file for the new volume group name, for example:
# mkdir /dev/vg03
# mknod /dev/vg03/group c 64 0x030000
Then you need to vgimport from your map file previously created with vgexport, for example:
# vgimport -v -s -m mapfile /dev/vg03
