ABORT TASK SET:
The ABORT TASK SET is used to clear all tasks in the specified Logical Unit
for the Initiator. (Same as the SCSI-2 Abort message)
The ABORT TASK (Same as the SCSI-2 Abort Tag message) is specified by the
ABTS Link Service.
Execution Management:
The direction of the SCSI data transfer is specified in the Execution Management.
The direction depends on the SCSI Command.
– FCP_CDB
The SCSI CDB (Command Descriptor Block) is contained in the FCP_CDB field.
The Command Link is not supported by the array controller. The Link bit shall be
set to 0. When one of these bits is set to 1, the array controller terminates the
command with a CHECK CONDITION status (Sense Key = ILLEGAL REQUEST).
– FCP_DL
The total length bytes of the SCSI data is set in the FCP_DL field. Data described
with the number of bytes according to the data length set in the FCP_CDB is
transferred irrespective of the value set in this field. The value in this field is
checked when the status is sent, and the check result is reflected on the
FCP_RSP.
