On sparc there is a restriction which applies to older machines.
If the disk was originally formatted on a machine with an old version of
the OBP it will have a disk label which cannot support slices larger than
2Gb. If you try to create any slice (not just swap) larger than 2Gb on
such a disk only the first 2Gb will be readable.
This is normally only a problem if you try to put a large disk into into a
very old 32 bit machine or move a disk between old and newer machines.
