1. Source File System umount
  (Source와 Target vg는 active 되어 있어야 함)

2. dd if=/dev/vg20/rlvol1 of=/dev/vg50/rlvol1 bs=1024k
            (Source)                  (Target)

3. fsck (Target)

4. extendfs -F vxfs /dev/vg50/rlvol1
(dd로 카피시 Target의 용량이 Source의 용량과 같아짐)

5. mount

6. Data 정합성 비교


예....

date;time dd if=/dev/vg20/rlvol1 of=/dev/vg50/rlvol1 bs=1024k

fsck -F vxfs -o full -y /dev/vg50/rlvol1

mount /dev/vg50/lvol1 /data10_new

vgdisplay -v /dev/vg50

lvdisplay -v /dev/vg50/lvol1 | more
diff /data10 /data10_new

diff /data10/IPES/QOS/SampleData /data10_new/IPES/QOS/SampleData

fsadm -F vxfs -b 71368704 /data10_new

diff /data10/IPES/QOS/StaticBackup /data10_new/IPES/QOS/StaticBackup

umount /data10_new

extendfs -F vxfs /dev/vg50/rlvol1

mount /dev/vg50/lvol1 /data10_new
