Physical volume- no free physical partitions
I was in smit, checking on disc space, etc. and it appears that one of our physical volumes that is part of a large volume group, has no free physical partitions. The server is running AIX 5.1. What would be the advisable step to take in this instance?

I just read that while creating a logical volume(LV) we can choose the region of the physical volume (PV) in which the LV should be created.
When I say region I mean: outer edge - outer middle - center - inner middle and inner edge.

vgsplit
VGSPLIT(8) System Manager's Manual VGSPLIT(8)
NAME
vgsplit - split a volume group into two
SYNOPSIS
vgsplit [--alloc AllocationPolicy] [-A|--autobackup {y|n}] [-c|--clustered {y|n}] [-d|--debug] [-h|--help] [-l|--maxlogicalvolumes MaxLogi-
calVolumes] [-M|--metadatatype type] [-p|--maxphysicalvolumes MaxPhysicalVolumes] [-n|--name LogicalVolumeName] [-t|--test] [-v|--verbose]
SourceVolumeGroupName DestinationVolumeGroupName [ PhysicalVolumePath ...]
DESCRIPTION
vgsplit moves one or more physical volumes from SourceVolumeGroupName into DestinationVolumeGroupName. The physical volumes moved can be
specified either explicitly via PhysicalVolumePath, or implicitly by -n LogicalVolumeName, in which case only physical volumes underlying
the specified logical volume will be moved.
If DestinationVolumeGroupName does not exist, a new volume group will be created. The default attributes for the new volume group can be
specified with --alloc, --clustered, --maxlogicalvolumes, --metadatatype, and --maxphysicalvolumes (see vgcreate(8) for a description of
these options). If any of these options are not given, default attribute(s) are taken from SourceVolumeGroupName.
If DestinationVolumeGroupName does exist, it will be checked for compatibility with SourceVolumeGroupName before the physical volumes are
moved. Specifying any of the above default volume group attributes with an existing destination volume group is an error, and no split will
occur.
Logical volumes cannot be split between volume groups. Vgsplit(8) only moves complete physical volumes: To move part of a physical volume,
use pvmove(8). Each existing logical volume must be entirely on the physical volumes forming either the source or the destination volume
group. For this reason, vgsplit(8) may fail with an error if a split would result in a logical volume being split across volume groups.
OPTIONS
See lvm for common options.
