To specify a slice on a disk with a SCSI controller on an x86 based system, follow the naming convention shown in the following figure.
If you have only one controller on your system, v is usually 0.
For SCSI controllers, w is the target address set by the switch on the back of the unit, and x is the logical unit number (LUN) of the drive attached to the target. If the disk has an embedded controller, x is usually 0.
To indicate the entire Solaris fdisk partition, specify slice 2 (s2).
