I would have to guess about issues with shrinking - and my best guess is that they have anticipated changes for "disks" that grow - in updating the VGDA structure, but that it is more difficult, or impossible for your current hdisk PV allocation to make he VGDA mapping smaller.
Maybe a reorgvg is needed to move "inner" partitions more to the edge - again I am guessing that a volume grows by getting a larger inner area.
So, maybe verify that the "inner" area is free with

Hi,
I am new to unix. I am working on Red Hat Linux and side by side on AIX also. After reading the concepts of Storage, I am now really confused regarding the terminologies

vgrename
VGRENAME(8) System Manager's Manual VGRENAME(8)NAME
vgrename - rename a volume group
SYNOPSIS
vgrename [-A|--autobackup{y|n}] [-d|--debug] [-h|--help] [-v|--verbose] { OldVolumeGroupPath NewVolumeGroupPath | OldVolumeName NewVol-
umeGroupName }
DESCRIPTION
vgrename renames an existing (see vgcreate(8) ) volume group.
OPTIONS
-A, --autobackup y/n
Controls automatic backup of VG metadata after the change ( see vgcfgbackup(8) ). Default is yes.
-d, --debug
Enables additional debugging output (if compiled with DEBUG).
-h, --help
Print a usage message on standard output and exit successfully.
-v, --verbose
Gives verbose information about vgrename's activities.
Examples
"vgrename /dev/vg02 /dev/my_volume_group" renames existing volume group "vg02" to "my_volume_group".
"vgrename vg02 my_volume_group" does the same.
DIAGNOSTICS
vgrename returns an exit code of 0 for success and > 0 for error:
1 new volume group directory for device special files already exists
2 old volume group directory for device special files doesn't exist
3 new volume group name is invalid
4 old volume group name is invalid
5 error checking existence of old volume group
7 volume group names are identical
8 new volume group already exists
9 error reading VGDA
10 error removing old VGDA from kernel
11 error removing old VGDA from lvmtab
12 error removing device special files for old volume group
13 error creating device special files for new volume group
14 error inserting new volume group name into lvmtab
15 error backinp up VGDA
16 error writing VGDA to lvmtab
17 error renaming volume group in kernel
95 driver/module not in kernel
96 invalid I/O protocol version
97 error locking logical volume manager
98 invalid lvmtab (run vgscan(8))
99 invalid command line
ENVIRONMENT VARIABLES
LVM_AUTOBACKUP
If this variable is set to "no" then the automatic backup of VG metadata is turned off.
LVM_VG_MAX_BACKUPS
This variable determines the backup history depth of kept VGDA copy files in /etc/lvmconf. It can be set to a positive number
between 0 and 999. The higher this number is, the more changes you can restore using vgcfgrestore(8).
