Just a minor observation:

Don't let era, our local "herder of useless cats", see that ;-)) :

.... awk '{ /PV IDENTIFIER/ print $3 }'....

would do the same as "....grep ...| awk ....", yes?

I have long given up on pointing out that backticks are considered harmful in the Korn shell and "`...`" should be replaced by "$(....)".

And for the audience: please use [ code ]...[ /code ]-tags when posting code. The difference is:

with code-tags:

Code:

for MyVG in `lsvg`
do
     echo "\n\n Volume Group: $MyVG\n------------------"
     for MyPV in `lsvg -p $MyVG|grep -v -e $MyVG -e PV_NAME|awk '{ print $1 }'`
     do
          MyID=`lspv $MyPV|grep 'PV IDENTIFIER'|awk '{ print $3}'`
          echo $MyPV $MyID
     done
done

and the same without:
for MyVG in `lsvg`
do
echo "\n\n Volume Group: $MyVG\n------------------"
for MyPV in `lsvg -p $MyVG|grep -v -e $MyVG -e PV_NAME|awk '{ print $1 }'`
do
MyID=`lspv $MyPV|grep 'PV IDENTIFIER'|awk '{ print $3}'`
echo $MyPV $MyID
done
done

       [-P|--partial] [--unitshHbBsSkKmMgGtTpPeE] [--version] [VolumeGroupName[VolumeGroupName...]]

       vgdisplay      --columns      |	    -C	    [--aligned][-d|--debug][-h|-?|--help]	[--ignorelockingfailure][--noheadings][--nosuffix]

       sSkKmMgGtTpPeE] [-v|--verbose] [--version] [VolumeGroupName[VolumeGroupName...]]

DESCRIPTION

       vgdisplay allows you to see the attributes of VolumeGroupName (or all volume groups if none is given) with it's physical and  logical  vol-
       umes and their sizes etc.

       vgs (8) is an alternative that provides the same information in the style of ps (1).

OPTIONS

       See lvm for common options and vgs for options given with --columns.

       -A, --activevolumegroups
	      Only select the active volume groups.

       -c, --colon
	      Generate colon separated output for easier parsing in scripts or programs.  N.B. vgs (8) provides considerably more control over the
	      output.

	      The values are:

	      1  volume group name
	      2  volume group access
	      3  volume group status
	      4  internal volume group number
	      5  maximum number of logical volumes
	      6  current number of logical volumes
	      7  open count of all logical volumes in this volume group
	      8  maximum logical volume size
	      9  maximum number of physical volumes
	      10 current number of physical volumes
	      11 actual number of physical volumes
	      12 size of volume group in kilobytes
	      13 physical extent size
	      14 total number of physical extents for this volume group
	      15 allocated number of physical extents for this volume group
	      16 free number of physical extents for this volume group
	      17 uuid of volume group

       -s, --short
	      Give a short listing showing the existence of volume groups.

       -v, --verbose
	      Display verbose information containing long listings of physical and logical volumes.  If given twice, also display verbose  runtime
	      information of vgdisplay's activities.

       --version
	      Display version and exit successfully.

       --columns|-C
	      Display output in columns, the equivalent of vgs.  Options listed are the same as options given in vgs (8).
