As discussed in the previous chapter, Fibre Channel allows a potentially very large number of available addresses. However, this large number of available addresses does not fit seamlessly into the current addressing model in the HP-UX operating system. To handle the number of possible addresses, the Fibre Channel Protocol (FCP) subsystem on HP-UX uses three methods of addressing:
Peripheral Device addressing
Logical Unit addressing
Volume Set addressing
But first, there are two major limitations and work-arounds that need to be explained.
Parallel SCSI has the capacity to handle 16 IDs (targets or devices) per bus, ...
