6.Command Specification
Case 4 (with PRTH=0);
With the tape already loaded, and with partition 1 active, the Delete Partition command issued with the Indicated
Partition Number set to 3 will delete partitions 4 and 5. SDX-450V will change the value of 5 in the Last Partition
Number field in the Volume Information in MIC to 3. No tape motion will take place.
After the completion of this command, the Unit Attention condition will be set for other Initiators, with ASC/ASCQ set
to 2A01, Mode Parameters changed and Mode Sense Page 11h will show the following:
Old tape layout:
Partition 0 Partition 1
Active Partition
New tape layout:
Partition 0 Partition 1
Active Partition
Case 5 (with PRTH=0);
With the tape already loaded, and with partition 3 active, the Delete Partition command issued with the Indicated
Partition Number set to 1 will be rejected with CHECK CONDITION. See Note 2.
Indicated Partition Number
Partition 0 Partition 1
Case 6; (with PRTH=1)
In case of the PRTH = 1, SDX-450V returns ready status after the cassette is inserted without tape threading. The
current physical position is the ODA of partition 1, because the tape is not threaded yet. Threading will position the
tape at the top of partition 2 - therefore, partition 2 and the preceding partitions cannot be deleted at this point;
partition 3, 4, and 5 may be deleted. Consequently, the Indicated Partition Number shall be greater than 2.
An AIT cassette is equipped with a lock mechanism for both reels preventing tape movement. This feature
guarantees that tape loading is done at the point of prior unload. However, if the AIT cassette is inserted into an 8mm
VCR, then the tape position will change, in which case SDX-450V will rewind the tape to PBOT, after detecting that
the load position is different from the unload position.
After the Mode Select Page 33h is processed by the drive, the following Parameters shall be changed:
a. Mode Sense Page 11h
b. Log Page 31h = Parameter Codes for Partitions deleted
c. Log Page 3Ch = Parameter Codes for Partitions deleted
d. Log Page 3Dh, Parameter Codes=0004h, 0015h, 0016h, and User Partition Notes for Partitions deleted
c. Log Page 3Eh, Parameter Codes = User Partition Notes for Partitions deleted.
After the command completes successfully Unit Attention is set for other Initiators.
