Hi,
if you want to reuse the data on the disk you should opt for vgimport.
If you want to discard the data, and use the diskspace, you should "pvcreate -f" first.

regards,
Thierry.

1- /dev/dsk/c... may differ from one system to other.

2- Vgimport in the first box and vgexport with -s option.

3- vgimport in the second box whit -s option too.

4- See:

Hi,
If you want to get ride of the LVM information of this disk you should use pvcreate -f onthat disk before adding it to an other vg.
If you wan't to use this vg on an other server, you will have to use vgimport.
But it is not possible to use this disk with the data on it for an other vg.

Once again... beware with pvcreate -f... Maybe

/dev/rdsk/c12t0d0 are different disk in two servers.

run:

dd if=/dev/rdsk/cxtxtx bs=1024 skip=8 count=9 | dd bs=8 skip=2 count=1 | od -x | head -1 .

To see if VGID is the same.

Hi Matrah,

If you want the disk to be part of the same VG on the new system as it was on the other system, you have to do a "vgexport" on the old system and a "vgimport" on the new system. IF on the other hand you want to remove the disk from a vg on the old system and add that disk in an existing vg on the new system, do a "vgreduce" on the old system, do a "pvcreate -f" on the disk first on new system and then do a "vgextend" to add the disk on the new system.

Hope this helps.
