IBM RS/6000 manual Location code is Defined as, Memory module in system board slot

GH is used to identify a port, device, or FRU. For example:

Ÿ For async devices GH defines the port on the fanout box. The values 15.

Ÿ For a diskette drive H defines which diskette drive 1 or 2. G is

Ÿ For all other devices GH is equal to 00.

For	integrated adapter, EF-GH		is the same as the definition for a	plugga
For	example, the location code for a diskette drive is 01-D1-00-00. A			secon
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

H defines the logical unit address of the device. Values of 0 to 255

There is also a bus location code that is generated as '00-XXXXXXXX' wh XXXXXXXX is equivalant to the node's unit address.

Examples of physical location codes displayed by AIX are:

Processor card in system board slot 1

P1-C1

Memory module in system board slot 2

P1-M2

Memory module 12 in card in system board slot 2

U1-P1-M2.12
