IBM RS/6000 Enterprise Server M80, Service Manual

For SCSI devices, the location code is defined as follows:
AB-CD-EF-G,H
| | | | |
| | | | Logical Unit address of the SCSI Device
| | | Control Unit Address of the SCSI Device
| | Connector ID
| devfunc Number, Adapter Number or Physical Location
Bus Type or PCI Parent Bus
Where:
v AB-CD-EF are the same as non-SCSI devices.
v
G defines the control unit address of the device. Values of 0 to 15 are valid.
v H defines the logical unit address of the device. Values of 0 to 255 are valid.
A bus location code is also generated as ’00-XXXXXXXX’, where XXXXXXXX is equivalent to the node’s
unit address.
Examples of physical location codes and AIX location codes are:
PCI adapter in primary I/O drawer, Slot 1
Location Code U0.1-P1-I1
AIX location Code 20-58
PCI adapter in secondary I/O drawer, Slot 1
Location Code U0.2-P1-I1
AIX location Code E0-58
AIX and Physical Location Code Reference Tables
