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:
1. PCI adapter in primary I/O drawer, slot 1
v Location Code U0.1-P1-I1
v AIX Location Code 11-08
2. PCI adapter in secondary I/O drawer, slot 1
v Location Code U0.2-P1-I1
v AIX Location Code 51-08
