Hardware Class Notes

SCSI Bus, Unit, and LUN

A device's SCSI Bus, SCSI Unit, and SCSI LUN are reported as the device attributes as shown in the table below when the Device Type Class is SCSI. Currently on HP-UX and Linux provide this data due to limitations in other operating systems.

Table 3.1. SCSI ID Mapping

SCSI IDSysInfo™ Device Field
SCSI Bus #Bus
SCSI Target/Unit #BusDevNum
SCSI LUNPort

In SysInfo™ Report format these attributes appear in the device|data|... fields. For example:

device|data|||sdd|||Bus|Bus Number|1
device|data|||sdd|||BusDevNum|Bus Device Number|10
device|data|||sdd|||Port|Bus Port Number|0

In this example the SCSI Bus number is 1, the SCSI Target is 10, and the SCSI LUN is 0.
