Hold State 1.7 Command Processing Exceptions 1.8 Data Block Addressing This chapter describes the basic logical specifications of the IDD command processing functions. Note: The IDD operates as the target (TARG) on the SCSI bus. In the explanations in this chapter, the IDD is mentioned as "TARG - Fujitsu MAX3073NC | Specifications - Page 20

In commands which send parameters necessary for executing - Fujitsu MAX3073NC | Specifications - Page 23
CDB specifying, that command ends with a CHECK CONDITION status. In the case of a command to change the data on the disk media, when there is an error in the CDB's specifications, the disk media is not changed by that command. But when there is an error in the parameters transferred in the DATA - Fujitsu MAX3073NC | Specifications - Page 24
Figure 1.4 shows the type of status that the IDD supports. The status is one byte of information sent from FREE phase forcibly through an ABORT TASK SET message, an ABORT TASK message, a CLEAR TASK SET message, a TARGET RESET message, a RESET condition or a SCSI bus error state, etc., the status - Fujitsu MAX3073NC | Specifications - Page 25

Therefore, this status is not reported. (4) BUSY status This status indicates that the IDD is in the busy state and it - Fujitsu MAX3073NC | Specifications - Page 26

(9) TASK SET FULL status This status is reported if processing examples which are the most basic operations on the SCSI bus. Furthermore, if disconnect processing is permitted, it may - Fujitsu MAX3073NC | Specifications - Page 27
