The possible values for CD depend on the adapter or card. For pluggable
adapters/cards this is a two digit slot number in the range from 01 to 99. However,
in the case of ISA cards these numbers do not actually correspond to the physical
slot numbers. They are simply based on the order the ISA cards are
defined/configured either by SMIT or the ISA Adapter Configuration Service Aid.
For integrated adapters the first character in CD is a letter in the range from A to Z.
This letter is based on the order that the integrated adapters are defined in residual
data and ensures unique location codes for the integrated adapters. The D is set to
0.
EF is the Connector ID. It is used to identify the adapter connector to which a
resource is attached.
GH is a port identifier, address, memory module, device, or FRU. It identifies a port,
device, or a FRU. GH has several meanings depending upon the resource type.
They are:
For memory cards GH defines a memory module. Values for GH are 1 through
16.
For systems that have memory modules that plug directly into the system planar
the location code are 00-00-00-GH where GH is the memory module slot. For
system that have memory cards with memory modules, the location code is
00-CD-EF-GH where CD is the card slot and GH is the memory module slot.
For caches GH defines the cache. Values for GH are 1 through 16.
For PCMCIAs GH defines the PCMCIA device. Values for GH are 1 through 16.
For async devices GH defines the port on the fanout box. 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 adapters, EF-GH is the same as the definition for a pluggable adapter.
For example, the location code for a diskette drive is 01-H0-00-00.
For SCSI the Location Code is defined as:
