As far as I know it is OK for anything BUT rootvg.
Export them, migrate, import and you should be OK.
For rootvg it can sort of work but the paths get all mucked up and you will need to migrate rootvg to new disks / luns after the move to stand any chance of sorting out the pathing mess.
HTH.

Has any one in this distribution list implemented SVC (SAN Volume Contoller - A solution from IBM) in your environment? If you have, do you have any do's / don'ts? Anything which you like sharing would be really appreciated.

Can anyone recommend me some reading material surrounding how AIX handles LUNs:
- with and without MPIO installed
- with and without SDD or SDDPCM installed
Where does lspath sit in all of this (MPIO layer?). Can a system be built with just MPIO software? Is MPIO software even needed?
I guess... (0 Replies)

I was wondering if there is a way of auto-detecting a new vpath, using IBM's SDD driver, on a Linux platform.
ON AIX it is a simple as running cfgmgr.

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).
