Operating Systems AIX Stale PPs in AIX, failed disks.. how to replace? Post 302922943 by c3rb3rus on Wednesday 29th of October 2014 10:43:06 AM

Thanks for the reply.

I am following your 2nd suggestion as this machine is going to be out its door in about 2 months (its over 5+ years old) and is a DR/testing box so not a production machine, less critical. My goal now is to keep it going for the next 2 months.

My goal is to get /usr1 (vg_usr1) working, removing the failed disks and making sure it is mirrored.

Sorry, perhaps I should have stated this first though your notes I am going to use on the new system we are putting in place.

I changed the policy to minimum, and tried to run reorgvg...

Code:
# lsvg vg_usr1
VOLUME GROUP:       vg_usr1                  VG IDENTIFIER:  000015010000d60000000141138f2577

0516-968 reorgvg: Unable to reorganize volume group.
0516-962 reorgvg: Logical volume loglv00 migrated.

Sounds like one of the pvs (hard drives) could be having an issue that is currently assigned to the vg?

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).
