Loop Initialization After Establishing Connections With The Init, And Subsequent Processing - Fujitsu MAA3182FC Series Manual

If the connection is interrupted, commands waiting in the queue are all aborted and no
response is returned.
Also, the LOGO (Extended Link Service) frame is returned as a response to the SCSI
command from the INIT.
An example of confirmation of connections that is performed by the INIT is shown below.
INIT (Initiator side)
(INIT#1) FCP_CMND (read)
(INIT#2) FCP_CMND (read)
(INIT#3) FCP_CMND (read)
(INIT#1) FCP_CMND (write)
(INIT#1) ADISC
(INIT#2) ADISC
(INIT#3) ADISC
Remark: This example is described with the premise that the INIT#1 read command is aborted by loop initialization.

processing
(4) Write related command operations
During write related command operations, before receiving of data, the INIT is notified in the
FCP_XFER_RDY frame of the volume of data which the device can receive and the pointer
for those data.
