AIX - mirror a jfs2log

Hi everybody,

I have a little problem with my AIX 6.1, PowerHA 6.1 LVM mirroring.

I accidentally created logical volume cpsabcd2lv with external jfs2log loglv00 in the same volume group cpsdata2vg. Then I mirrored LV cpsabcd2lv on the second LUN in VG cpsdata2vg. My journal is unmirrored and only on one LUN.

Code:

# lsvg cpsdata2vg
VOLUME GROUP:       cpsdata2vg               VG IDENTIFIER:  00fb518c00004c0000000169445f4c2c
VG STATE:           active                   PP SIZE:        1024 megabyte(s)
VG PERMISSION:      read/write               TOTAL PPs:      6142 (6289408 megabytes)
MAX LVs:            256                      FREE PPs:       441 (451584 megabytes)
LVs:                2                        USED PPs:       5701 (5837824 megabytes)
OPEN LVs:           2                        QUORUM:         2 (Enabled)
TOTAL PVs:          2                        VG DESCRIPTORS: 3
STALE PVs:          0                        STALE PPs:      0
ACTIVE PVs:         2                        AUTO ON:        no

Node ID:            1                        Active Nodes:       2 3 4
MAX PPs per VG:     32768                    MAX PVs:        1024
LTG size (Dynamic): 256 kilobyte(s)          AUTO SYNC:      no
HOT SPARE:          no                       BB POLICY:      relocatable
MIRROR POOL STRICT: off
PV RESTRICTION:     none                     INFINITE RETRY: no
DISK BLOCK SIZE:    512                      CRITICAL VG:    no

 # lspv

hdisk36         00fb518c4457e71a                    cpsdata2vg      concurrent
hdisk37         00fb518c4457f895                    cpsdata2vg      concurrent

# lslv -l loglv00
loglv00:N/A
PV                COPIES        IN BAND       DISTRIBUTION
hdisk36           001:000:000   100%          000:001:000:000:000

 # lsvg -l cpsdata2vg
cpsdata2vg:
LV NAME             TYPE       LPs     PPs     PVs  LV STATE      MOUNT POINT
cpsabcd2lv          jfs2       2850    5700    2    open/syncd    /cpsabcd2
loglv00             jfs2log    1       1       1    open/syncd    N/A

I know that I can´t change external jfs2log to INLINE, but is there a smart way how to repair it/mirror it? Hdisk36 and hdisk37 are the same size and contain only VG cpsdata2vg.
What if I just add copy of the LV loglv00 to hdisk37? Will it add a copy behind the LV cpsabcd2lv or this overwrite LV cpsabcd2lv?

Code:

mklvcopy loglv00 2 hdisk37

Thank you for suggestions.

vgcfgrestore

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

NAME

       vgcfgrestore - restore volume group descriptor area

SYNOPSIS

       vgcfgrestore [-d|--debug] [-f|--file filename] [-l[l]|--list] [-h|--help] [-M|--Metadatatype1|2] [-t|--test] [-v|--verbose] VolumeGroupName

DESCRIPTION

       vgcfgrestore  allows  you  to  restore  the metadata of VolumeGroupName from a text backup file produced by vgcfgbackup.  You can specify a
       backup file with --file.  If no backup file is specified, the most recent one is used.  Use --list for a list of the available  backup  and
       archive files of VolumeGroupName.

OPTIONS

       -l | --list -- List files pertaining to VolumeGroupName
	      List  metadata  backup  and  archive  files  pertaining  to VolumeGroupName.  May be used with the -f option.  Does not restore Vol-
	      umeGroupName.

       -f | --file filename -- Name of LVM metadata backup file
	      Specifies a metadata backup or archive file to be used for restoring VolumeGroupName.  Often this file has been created with  vgcfg-
	      backup.

       See lvm for common options.

REPLACING PHYSICAL VOLUMES

       vgdisplay  --partial  --verbose will show you the UUIDs and sizes of any PVs that are no longer present.  If a PV in the VG is lost and you
       wish to substitute another of the same size, use pvcreate --restorefile filename --uuid uuid (plus additional arguments as appropriate)	to
       initialise  it with the same UUID as the missing PV.  Repeat for all other missing PVs in the VG.  Then use vgcfgrestore --file filename to
       restore the volume group's metadata.
