Full Discussion: AIX striped LV - lslv stripe width has wrong value
Operating Systems AIX AIX striped LV - lslv stripe width has wrong value Post 302380521 by Scott on Tuesday 15th of December 2009 11:33:12 AM

Hi zaxxon,

I used odmget/odmchange to update it.

I was about to run savebase as you suggested, but noticed this:

Code:
# lsvg -M data01vg
data01vg
0516-304 : Unable to find device id 00c9f44e00004c0000000103d13ca2e0.1 in the Device
        Configuration Database.

It's the same for every VG (even rootvg!).

In the ODM I see:

Code:
CuAt:
        name = "data01lv"
        attribute = "lvserial_id"
        value = "s"
        type = "R"
        generic = "D"
        rep = "n"
        nls_index = 648

what I suspect should be more like:

Code:
CuAt:
        name = "data01lv"
        attribute = "lvserial_id"
        value = "00c9f44e00004c0000000103d13ca2e0.1"
        type = "R"
        generic = "D"
        rep = "n"
        nls_index = 648

(and it's the same for every LV)

I don't know what happened here, or when. A restore of ODM from an old backup fixed this.

With the ODM looking OK again, I ran savebase, and now need to schedule a reboot.

Failing that I'll back it up, create it anew.

Thanks for the help.


Hi wwwzviadi,
Yes, there's definately 8 disks. Everything shows this (lspv, lsvg -p, lslv -l, etc.)

Playing around, it appears what might have happened (a long time ago!), goes something like:
Code:
# mkvg -fSy scottvg hdisk71 hdisk72 hdisk73 hdisk74
scottvg
# mklv -t jfs2 -y scottlv -S 64K scottvg 1536 hdisk71 hdisk72 hdisk72 hdisk73 hdisk74
scottlv
# lslv scottlv
LOGICAL VOLUME:     scottlv                VOLUME GROUP:   scottvg
LV IDENTIFIER:      00c9f44e00004c000000012593214e8c.1 PERMISSION:     read/write
VG STATE:           active/complete        LV STATE:       closed/syncd
TYPE:               jfs2                   WRITE VERIFY:   off
MAX LPs:            1540                   PP SIZE:        16 megabyte(s)
COPIES:             1                      SCHED POLICY:   striped
LPs:                1540                   PPs:            1540
STALE PPs:          0                      BB POLICY:      relocatable
INTER-POLICY:       maximum                RELOCATABLE:    no
INTRA-POLICY:       middle                 UPPER BOUND:    5
MOUNT POINT:        N/A                    LABEL:          None
MIRROR WRITE CONSISTENCY: on/ACTIVE
EACH LP COPY ON A SEPARATE PV ?: yes (superstrict)
Serialize IO ?:     NO
STRIPE WIDTH:       5
STRIPE SIZE:        64k
DEVICESUBTYPE : DS_LVZ

Didn't know it was possible!

Thanks.

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).
