Chapter 4. Location Codes The RS/6000 7046 Model B50 uses physical location codes in conjunction with AIX location codes to provide mapping of the failing field replaceable units. The location codes are produced by the system unit's firmware and AIX. Physical Location Codes Physical location codes provide a mapping of logical functions in a pl[...]

1-C1.1 Identifies CPU 1 on CPU card 1 on planar 1. P2/Z1-A3.1 Identifies a SCSI device with a SCSI address of LUN 1 at SCSI ID 3 attached to SCSI bus 1 from planar 2. P1-I2#E3.2 Identifies the second cable in a series of cables attached to Ethernet controller 3 in slot 2 (I2) on planar 1. Depending on the AIX and firmware levels, AIX Diagnostics ma[...]

AIX Location Codes The basic formats of the AIX location codes are:  For non-SCSI devices/drives: AB-CD-EF-GH  For SCSI devices/drives: AB-CD-EF-G,H Non-SCSI Devices/Drives The location code for for planars, cards, and non-SCSI devices is defined as: AB-CD-EF-GH | | | | | | | Device/FRU/Port ID | | Connector ID | devfunc Number, Adapter Numbe[...]

 The AB value identifies a bus type or PCI parent bus as assigned by the firmware.  The CD value identifies adapter number, adapter's devfunc number, or physical location. The devfunc number is defined as the PCI device number times 8, plus the function number.  The EF value identifies a connector.  The GH value identifies a port, [...]

 For async devices, GH defines the port on the fanout box. The values are 00 to 15.  For a diskette drive, H identifies either 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 dr[...]
