Renaming Volume groups

[Gerardo Mora]

Hi!

I have 2 servers connected to a XP-256 disk array using HP-UX 11.0, I need to move all of the volume groups from server A to server B except VG00, I would like to export them from server A and then import them to server B using a map file, ex.: vgimport -v -s -m vg01.map vg01, but some of the volume groups names of server A exists in B

Is possible rename the volume groups name at the import time or how can do that?

Thanks!

Yes, you may use a different vg name during import. For example:

mkdir /dev/vg05
mknod /dev/vg05/group c 64 0x050000
vgimport -v -s -m vg01.map /dev/vg05

Hi,

You can rename them when you vgimport them on the second box. You'll have to make the directory for the new volume group under /dev any way, and you can give it the new name then. LVM doesn't care what you name it, as long as it is unique and the vg has a unique minor number for the group file.

Hi:

Renaming a volume group at the time you 'vgimport' it is easily done.

Simply specify the new name in the 'vgimport' command -- it doesn't matter what the old name was.

One thing to note: if you use a map file, your LVOLs will have the same names they had on the old system. You can 'cat' the map file, there's no real magic there, it is just the names of the LVOLs, so they don't get set back to LVM defaults.

If you import an exported volume group without the map file (vgscan, etc), LVM will just give the LVOLs its default names (lvol0, lvol1, etc, in order).

As has been pointed out, it is easy to rename the VG upon import, but you didn't mention whether or not you want to keep the LVOL names, which can ge changed as well at this time, if needed.

Hope it helps!! --bmr
