There is one additional step required when partitioning a hard drive for
UltraPenguin. You must create the third partition of every disk as type
Whole Disk spanning from cylinder 0 to the end of the disk. It
shouldn't be used in any way, but it must exist. You can still create
other partitions as you normally would.
Note that this partition will already exist on any disk that has been used
underSunOS or Solaris. If you are partitioning a new disk,
you can use fdisk's ``s'' command to create a standard disk label (which
includes the whole-disk partition). If you don't care for the size of the
other partitions created by ``s'', you can delete those partitions
and recreate them with the sizes you want.
