20 Processing SCSI Information Chapter 1
Processing SCSI Information
The following section describes how the bridge processes SCSI information
when attached to FC hosts. (See Figure 8 on page 21.)
1. A FC host issues a command. The FC host encapsulates the command in
the FC protocol and sends the packet to the bridge.
2. The FC controller in the bridge receives the packet, interprets the FC
information, and places the packet in buffer memory.
3. The bridge’s processor interprets the information and programs a SCSI
controller to process the transaction.
4. The SCSI controller sends the command to the SCSI device (target).
5. The SCSI target interprets the command and executes it.
6. Data flows between the FC host and SCSI target through payload buffers.
(See Figure 8 on page 21.)
7. Response information flows from the SCSI target back to the FC host.
(See Figure 9 on page 21.)
