v The - (dash) separator character represents a normal structural relationship wherethe child is a separate physical package and it plugs into (or is connected to) theparent. For example, P1-C1 is a processor card (C1) plugged into a planar (P1), orP1-M1 is a memory card (M1) plugged into a planar (P1).v The / (slash) separator character separates the base location code of a function fromany extended location information. A group of logical devices can have the samebase location code because they are all on the same physical package, but mayrequire extended location information to describe the connectors they support. Forexample, P2/S1 describes the location of the serial port 1 controller and its connector(S1), which is located on planar P2 (its base location code), but the / indicates thatfurther devices can be connected to it at the external S1 serial connector. Thekeyboard controller and its connector likewise have location code P2/K1, whichmeans they have the same base location code (P2) as serial port 1, but a differentexternal connector. In contrast, the location code P2-K1 actually points to the deviceconnected to connector K1; that is, the keyboard. The location code P2/Z1 indicatesan integrated SCSI controller which drives connector Z1, while location codes ofP2-Z1-... point to the actual SCSI bus and devices.v The # (pound sign) separator character indicates a cable connection between aconnector and parent.The following are examples:v P1-C1 identifies processor card C1 plugged into planar P1.v P1-M1 identifies memory card M1 plugged into planar P1.v P2/S1 identifies serial port 1 controller on I/O board P2, or the connector for serialport 1.v P1-K1 identifies a keyboard attached to connector K1 on planar P1.v P2/Z1 identifies an integrated SCSI controller on planar P2 which drives connectorZ1.v P2-Z1-... points to the actual SCSI bus and devices attached to Z1.The . (period) identifies sub locations (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,H10 Service Guide
