multiple instances of same vg on same AIX machine
hi,
i am new to AIX and to this forum as well. Can you please help me out with following issue/requirement

1) I have one physical volume (pv1) (a scsi disk). (pv1) on 1st AIX machine. I have a single volume group on it(vg1).
2)I removed it from the 1st AIX machine and exported to the 2nd AIX machine. I am able to successfully import the vg1 and use it.
3) Now i got a new physical volume (pv2) on 1st AIX machine, and created the same volume group on it i.e vg1. (it has some updated information than the old volume group vg1).
4) Now i removed from 1st AIX machine and exported to 2nd AIX machine. 5) Now when i try to import this new vg1 on AIX2 it says vg1 is already used.

But i want to have both the volume groups (old vg1 and new vg1) on the same AIX server (2nd one). So some one can help me how i can do it? I dont want to use different vg names.

I have AIX 6.1 on 64bit kernel

pvremove

pvremove(1M)															      pvremove(1M)

NAME

       pvremove - remove LVM data structure from a physical volume

SYNOPSIS

DESCRIPTION

       The  command  clears  the LVM data structure on a disk, so that it is no longer an LVM physical volume.	The device may then be used by the
       file system or by other volume managers.

       The operation is denied if pv_path is assigned to a volume group.  The command only clears the LVM data structure on a  disk  if  the  disk
       does not belong to a volume group.  This avoids accidentally removing a valid physical volume under a volume group.  If the physical volume
       to be removed belongs to a volume group, use the command to first remove the volume group associated with the physical volume.

   Arguments
       recognizes the following arguments:

	      pv_path	The character (raw) device path name of a physical volume.

EXTERNAL INFLUENCES

   Environment Variables
       determines the language in which messages are displayed.

       If is not specified or is null, it defaults to "C" (see lang(5)).

       If any internationalization variable contains an invalid setting, all internationalization variables default to "C" (see environ(5)).

EXAMPLES

       Remove LVM data structure on the physical volume
