As mentioned previously, there are three methods used by HP-UX for Fibre Channel addressing in order to work around the HP-UX limitations.
 These limitations will be resolved with a new version of HP-UX, soon to be released.
Peripheral Device addressing
Logical Unit addressing
Volume Set addressing
The Fibre Channel Protocol (FCP) has a very large address space mapped onto the parallel SCSI address model of HP-UX. The FCP portion of the SCSI subsystem on HP-UX handles the large target address space associated with Fibre Channel by creating multiple virtual SCSI buses.
The FCP ...
