of 0-9, and A-F (hex numbers). This allows the location code to uniquely identify
multiple adapters on individual PCI cards.
For pluggable ISA adapters, CD is equal to the order the ISA cards
defined/configured either by SMIT or the ISA Adapter Configuration Service Aid.
For integrated ISA adapters, CD is equal to a unique code identifying the ISA
adapter. In most cases this is equal to the adapter's physical location code. In cases
where a physical location code is not available, CD is be FF.
EF is the connector ID. It is used to identify the adapter's connector that a resource
is attached to.
GH is used to identify a port, device, or FRU. For example:
For async devices GH defines the port on the fanout box. The values are 00 to
15.
For a diskette drive H defines which diskette drive 1 or 2. G is always 0.
For all other devices GH is equal to 00.
For 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.
For SCSI the location code is defined as:
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.
There is also a bus location code that is generated as '00-XXXXXXXX' where
XXXXXXXX is equivalent to the node's unit address.
