(5) INTERMEDIATE status
This status indicates that a command which specifies a link (except the last command in a group of
linked commands with “1” as its Link bit) has been completed normally. If a command which
specifies a link is completed abnormally and the CHECK CONDITION status or RESERVATION
CONFLICT status is reported, the command link is broken an the subsequent linked commands are
not executed.
(6) INTERMEDIATE CONDITION MET Status
This status is reported when it is possible to secure the cache memory area necessary to read all the
logical data blocks specified in a PRE-FETCH command which specifies a link (in the case of
“Immed = 1”), or when reading of all the specified logical data blocks is completed (in the case of
“Immed = 0”).
The IDD does not support the PRE-FETCH command. Therefore, this status is not reported.
(7) RESERVATION CONFLICT status
This status indicates that the IDD is reserved by another INIT, and that use is impossible until the
reserved status is canceled. Normally, an INIT which receives this status reissues the original
command after waiting an appropriate period of time.
(8) COMMAND TERMINATED status
This status is reported when the IDD has completed the executing input/output operation when it
received a TERMINATE I/O PROCESS message from the INIT.
(9) QUEUE FULL status
This status is reported if the IDD cannot register a received tagged command in the command
queue because there is no empty space in the command queue.
