SCSI Devices/DrivesFor SCSI devices, the location code is defined as follows: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 LocationBus Type or PCI Parent BusWhere 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.A bus location code is also generated as ’00-XXXXXXXX’ where XXXXXXXX is equivalent to the node’sunit address.Examples of physical location codes displayed by AIX are as follows:v Memory DIMM 2 of on system backplane P1:U0.1-P1-M2Examples of AIX location codes displayed are as follows:v Pluggable PCI adapters:1Z-08 Any PCI card in slot 11c-08 Any PCI card in slot 21f-08 Any PCI card in slot 31n-08 Any PCI card in slot 41H-08 Any PCI card in slot 51V-08 Any PCI card in slot 6v Device attached to SCSI controller:10-60-00-4,0 Device attached to integrated SCSI Port 1Multiple FRU Callout InstructionsIf an eight-digit error code appears in the operator panel display or in Chapter 5, “Error Code to FRUIndex,” on page 159, a location code for a failing part may also be specified. If the location code includesa blank space followed by a lowercase x followed by a number, this is an error code with multiple FRUcallouts. This error can typically happen with memory DIMMs or processors, and may involve mixed typesof parts. In this case, check the system’s configuration for FRU part numbers to determine the appropriateset of FRUs.You can determine the FRU part numbers of the electronic assemblies in the entire system by using theservice processor menus. From the General User menu, select Read VPD Image from Last System Boot,then enter 90 to display detailed Vital Product Data (VPD).If the system is running AIX, you can determine the FRU part numbers of the electronic assemblies in apartition by using thelscfg -vp | pg command. This command displays the detailed VPD of the electronic assemblies in thesystem. Notice that the FRU part number information for processors and memory DIMMs may be at thebottom of the command’s output.26 EserverpSeries 615 Service Guide
