김병수님 좀 봐주세요.

항상 답변 감사드립니다.



Mirror관련 질문 드렸던 사람인데요.

가르쳐 주신 대로 명령을 실행했더니 다음과 같이 나오네요.



# swlist -l fileset |grep -i mirror

LVM.LVM-MIRROR-RUN B.11.23 LVM Mirror

PHCO_31709.LVM-MIRROR-RUN 1.0 LVM.LVM-MIRROR-RUN



위 결과물에서 LVM.LVM-MIRROR-RUN은 무슨 소프트웨어인지요?



OS는 11i v2 Foundation OE (May, 2005) 입니다.

참조하시기 바랍니다.



MIRROR/UX: Determine If MirrorDisk/UX Is Installed (10.X / 11.X) DocId: KBAN00000249 Updated: 20030117



DOCUMENT

To see if MirrorDisk/UX is installed and configured, enter (on the command

line):



swlist -l fileset -a state | grep -i mir



On both 10.X and 11.X systems, the result should be:



LVM.LVM-MIRROR-RUN configured



Another way of confirming that MirrorDisk/UX is installed on the machine is to

run the command "what" on an LVM binary. Since the binary "lvextend" is used

to create mirroring, enter:



what /usr/sbin/lvextend



The following will be displayed if MirrorDisk/UX is installed:



$Revision: 82.26.1.9.1.31 $ MIRROR PRODUCT



Example:



Following is a vgdisplay of VG03. In this case, /dev/vg03/lvol1 is mirrored:



/usr/sbin/vgdisplay -v vg03

To confirm that a logical volume has been correctly configured for mirroring,

enter:



(In this example, lvol1 of vg03 has been mirrored)



/usr/sbin/lvdisplay -v /dev/vg03/lvol1



The result should be:
