Hello

@bakunin and @rbatte1 thank you for your responses.

@rbatte1, The request from my customer was that the database was decommissioned on three servers(LPARS) and that it was ok to remove the file systems (LV's) and reclaim the disks, which belong to a SAN. Because these disks belong to a SAN there is a cost to them, thus the reason for reclaiming them. Also included in the request was to reclaim one DNS and IP per server as it too was no longer needed. What the IP was used for, I do not know.

@bakunin - The setup on all three servers is that the list of 4 or 5 LV's belong to one volume group and each VG has 1 disk assigned to it with the expception of one VG, it has 2 disks. From the looks of it, the general how-to you posted is fine. I have a good direction I can follow. All I really need is concerning removing the IP.

Thank you

Joe

vgreduce

VGREDUCE(8)						      System Manager's Manual						       VGREDUCE(8)

NAME

       vgreduce - reduce a volume group

SYNOPSIS

       vgreduce  [-a|--all] [-A|--autobackup y|n] [-d|--debug] [-h|-?|--help] [--removemissing] [-t|--test] [-v|--verbose] VolumeGroupName [Physi-
       calVolumePath...]

DESCRIPTION

       vgreduce allows you to remove one or more unused physical volumes from a volume group.

OPTIONS

       See lvm for common options.

       -a, --all
	      Removes all empty physical volumes if none are given on command line.

       --removemissing
	      Removes all missing physical volumes from the volume group, if there are no logical volumes allocated on those. This resumes  normal
	      operation of the volume group (new logical volumes may again be created, changed and so on).

	      If this is not possible (there are logical volumes referencing the missing physical volumes) and you cannot or do not want to remove
	      them manually, you can run this option with --force to have vgreduce remove any partial LVs.

	      Any logical volumes and dependent snapshots that were partly on the missing disks get removed completely. This includes those  parts
	      that lie on disks that are still present.

	      If your logical volumes spanned several disks including the ones that are lost, you might want to try to salvage data first by acti-
	      vating your logical volumes with --partial as described in lvm (8).
