Hi Marcelo,

have you already tried it with the SAM?
perhaps this works. Ok then you can look
in the man's of the VG commands under /usr/sbin.
I would remove it and create a new one

Hi:

This isn't tricky. Simply do this:

# unmount all associated logical volumes in the volume group to be changed

# vgchange -a n /dev/oldvgname

# vgexport ???m /tmp/vgoldname.map /dev/oldvgname

# mkdir /dev/newvgname

# mknod /dev/newvgname/group c 64 0x0X0000 (where X is a unique number not already used)

# vgimport ???m /tmp/vgoldmapfile /dev/newvgname /dev/dsk/

# vgchange -a y /dev/newvgname

Regards!

hi,


bdf |grep vgxx

umount all the FS''s belonging to the VGxx.

Also, make sure it has no raw lv''s which are being used.

ll /dev/vgxx/group >/tmp/vgxx-ls

vgexport -v -m /tmp/vgxx.map /dev/vgxx

mkdir /dev/vgyy
mknod /dev/vgyy/group c 64 0x??0000

vgimport -v -m /tmp/vgxx.map /dev/vgyy

Hello,

I think you cannot do it. Even using vgexport and vgimport... I think the machine would still be expecting the original name and may complain. I would remove it and create it again.

But if JRF says you can, then you can. I just didn't want to try it and having to boot an ignite tape immediately afterwards.

You always learn new things through here :-)

Hi,
JRF's way of renaming vg works fine.
Don't forget to modify the fstab if there is filesystems on the vg.
