Variant 2
In the following we show the replacement of hdisk13 (DC02) with hdisk15 (DC02), even if 50% more physical partitions have to be synchronized. The graphic shows that the highest logical partition that hdisk13 (DC02) uses, is LP 0010. (The hdisk13 is used there in mirror copy 2, which brings us to variant 2.)
In variant 2, the mirror copies containing the source physical volume are first removed. The logical volume has then 2 mirror copies only. Then the target physical volume is inserted in the middle as mirror 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 replace hdisk13 (DC02) by hdisk15 (DC02) using migratepv:
# migratepv -l lv00 hdisk13 hdisk15
We are again following the work of migratepv graphically.
