Variant 2
In order to demonstrate variant 2 once, we go back to the initial state and this time we replace the hdisk14 (DC02). The graphic shows that the highest logical partition that the hdisk14 (DC02) uses is also LP 0008. (The hdisk14 is used there in mirror copy 2, which brings us to variant 2.)
With variant 2, the target physical volume is added at the back as mirror copy 3. At the end of migratepv, the physical partitions of copy 3 become copy 2. Since only physical volumes from DC02 are to be used in mirror copy 2, only hdisk15 (DC02) can be used as the target physical volume.
So we exchange hdisk14 (DC02) for the hdisk15 (DC02) using migratepv:
# migratepv -l lv00 hdisk14 hdisk15
We are again following the work of migratepv graphically.
