Completion of Loop Initialization

Figure 1.64 General public loop initialization sequence
At this point, Public Loop establishes between Fabric and Drive.
1.13 Dual Loop
This drive has a Dual Port configuration with two ports (A, B). Viewed from the
Fibre Channel Interface, these two ports appear to exist as two independent
devices.
Even though these two ports are independent to the interface, since they use the
storage medium in common, internally, during reading or writing from one of the
ports, read or write requests from the other port must wait.
The matrix for transmitting and receiving of frames at the interface is defined as
shown in Table 1.42.
