#
# Name:
#       cllvmcmd.sh
#
# Description:
#    Wrapper for all of the LVM commands that have an optional list of
#    physical volumes.  Translates the physical volume id's into physical
#    volume names that can be used by the AIX LVM commands.
#
#    Arguments for the various commands are passed in as follows
#
#       -extendvg Switches VolumeGroup DiskList
#
#       -reducevg Switches VolumeGroup DiskList
#
#       -unmirrorvg Switches VolumeGroup [DiskList]
#
#       -mklvcopy Switches LogicalVolume Copies VolumeGroup [DiskList]
#
#       -rmlvcopy Switches LogicalVolume Copies VolumeGroup [DiskList]
#
#       -rmlv Switches LogicalVolume
#
#       -mklv Switches VolumeGroup NumberOfLP's
#
#       -extendlv Switches LogicalVolume NumberOfLP's [DiskList]
#
#       -chlv Switches LogicalVolume...
#
#       -rmlv Switches LogicalVolume...
#
#       -extendvg4vp Switches VolumeGroup DiskList
#
#       DiskList is a comma separated list of physical volume id's
#
# Return Values:
#    0   Success
#    1   Failure
