Figure C.1 Example Fibre Address Conversion
Note: Use fixed address AL_PA (0xEF) when using iSCSI.
CCI converts fibre-channel physical addresses to SCSI target IDs (TIDs) using a conversion
table (see Figure C.2). Table C.1 shows the current limits for SCSI TIDs and LUNs on various
operat
ing systems.
