Fibre Channel to SCSI Protocol Process
This section describes the steps the router uses to convert FC host protocol to
SCSI device protocol.
Figure 10 and the supporting table illustrate and define this
process.
Figure 10: Converting Fibre Channel to SCSI process
Item Process
1
A Fibre Channel host issues an encapsulated FCP protocol
command packet to the router
2
The router Fibre Channel controller interprets the Fibre Channel
information, and places the packet in buffer memory.
3
The router interprets the Fibre Channel information packet and
programs the router SCSI controller to process the transaction.
4
The router SCSI controller sends the command to the SCSI device
(target).
5
The SCSI target interprets the command and executes it.
