Prior to use by ZFS or even format, fdisk must be run on the x85 architecture.  With Solaris 10, fdisk is used in the traditional PC way to define a Solaris2 partition.

Solaris x86, including Solaris 11, then treat the Solaris2 fdisk partition like a whole disk.  An SMI disk label must be placed and then slices defined in the traditional Solaris manner.

A slice can then be used by ZFS for use in a pool.

In this example, we are using SATA target 4 (the fifth drive on a six disk SATA controller).  SATA targets, like SCSI targets, start counting at zero.
