For an integrated adapter, EF-GH is the same as the definition for a pluggable adapter. For example, the
location code for a diskette drive is 01-D1-00-00. A second diskette drive is 01-D1-00-01.
SCSI Devices/Drives
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 AB-CD-EF are the same as non-SCSI devices.
G defines the control unit address of the device. Values of 0 to 15 are valid.
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 displayed by AIX are as follows:
v Processor card C1 plugged into CEC backplane P1:
U0.1-P1-C1
v Processor card C2 attached to CEC backplane P1:
U0.1-P1-C2
v Memory DIMM in slot 2 of processor card C1 attached to CEC backplane P1:
U0.1-P1-C1-M2
Examples of AIX location codes displayed are as follows:
v Integrated PCI adapter:
10-80
10-60
10-88
Ethernet
Integrated SCSI Port 1 (internal)
Integrated SCSI Port 2 (external)
