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

LVs:                2                        USED PPs:       5701 (5837824 megabytes)

STALE PVs:          0                        STALE PPs:      0

MAX PPs per VG:     32768                    MAX PVs:        1024
LTG size (Dynamic): 256 kilobyte(s)          AUTO SYNC:      no

MIRROR POOL STRICT: off
PV RESTRICTION:     none                     INFINITE RETRY: no
DISK BLOCK SIZE:    512                      CRITICAL VG:    no

 # 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 canĀ“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.
