Location Code format
The basic format of the location code is:

| “G” is the SCSI bus | ID | (PUN) | of the | device | and | “H” | is the | Logical | Unit | ||||
| Number | (LUN). |

The | “AB” value identifies the bus type as follows: |

The “EF” value, as generated by the firmware, is always 00.
The “GH” value (except for SCSI devices) is a subsystem dependent “index” value indicating subordinate devices of the parent identified by the
