v For pluggable PCI adapters/cards, CD is the device's devfunc number (PCI device
number times 8, plus the function number). The C and D are characters in the range
of 0-9, and A-F (hex numbers). Location codes therefore uniquely identify multiple
adapters on individual PCI cards.
v For pluggable ISA adapters, CD is equal to the order of the ISA cards
defined/configured either by SMIT or the ISA Adapter Configuration Service Aid.
v For an integrated ISA adapters, CD is equal to a unique code identifying the ISA
adapter. In most cases, this code is equal to the adapter's physical location code. In
cases where a physical location code is not available, CD will be FF.
EF is the connector ID. It is used to identify the adapter's connector to which a resource
is attached.
GH is used to identify a port, device, or FRU. For example:
v For async, devices GH defines the port on the fanout box. The values re 00 a to 15.
v For a diskette drive, H identifies either diskette drive 1 or 2. G is always 0.
v For all other devices, GH is equal to 00.
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:
