The . (period) identifies sublocations (DIMMs on a memory card or SCSI addresses).The following are examples:v P1-M1.4 identifies memory DIMM 4 on memory card 1 plugged into planar P1.v P1-C1.1 identifies processor 1 on processor card 1 plugged into planar P1.v P2-Z1-A3.1 identifies a SCSI device with SCSI address of LUN 1 at SCSI ID 3attached to SCSI bus 1, which is integrated on planar P2.v P2.1 identifies a riser card plugged into planar P2.AIX Location CodesThe basic formats of the AIX location codes are as follows:v For non-SCSI devices/drives:– AB-CD-EF-GHv For SCSI devices/drives:– AB-CD-EF-G,HNon-SCSI Devices/DrivesFor planars, cards, and non-SCSI devices, the location code is defined as follows:AB-CD-EF-GH| | | || | | Device/FRU/Port ID| | Connector ID| devfunc Number, Adapter Number or Physical LocationBus Type or PCI Parent Busv The AB value identifies a bus type or PCI parent bus as assigned by the firmware.v The CD value identifies adapter number, the adapter’s devfunc number, or physicallocation. The devfunc number is defined as the PCI device number times 8, plus thefunction number.v The EF value identifies a connector.v The GH value identifies a port, address, device, or FRU.Adapters and cards are identified only with AB-CD.The possible values for AB are:00 Processor bus01 ISA bus02 EISA bus03 MCA bus04 PCI bus used in the case where the PCI bus cannot be identified05 PCMCIA busesxy For PCI adapters where x is equal to or greater than 1. The x and y are characters in therange of 0-9, A-H, J-N, P-Z (O, I, and lower case are omitted) and are equal to the parentbus’s ’ibm, aix-location’ open firmware property.The possible values for CD depend on the adapter/card:Chapter 1.
