- Right, just
- extendvg yourvg hdisk857
- migratepv hdisk1 hdisk857
- migratepv hdisk2 hdisk857
- reducevg yourvg hdisk1
- reducevg yourvg hdisk2
-
-
- migratepv's are cool, as long as you don't have a
- dump device or boot logical volume on the disk,
- then it just gets more complicated, but it
- can be done.

- Later,
