Replacing a working non-rootvg Physical Volume

1. Install and configure the new physical volume.
2. Add the new physical volume to the volume group.
   1. # extendvg <volume group> <hdisk# of new physical volume>
3. If the logical volumes on the old physical volume are mirrored, break the mirror.
   1. # unmirrorvg rootvg <hdisk# of old physical volume
4. Migrate the logical volumes to the new physical volume.
   1. # migratepv <hdisk# of old physical volume> <hdisk# of new physical volume>
5. Remove the old physical volume from the volume group.
   1. # reducevg <volume group> <hdisk# of old physical volume>
