SDX-700C rewind the tape to Bottom of Active Partition, after Delete Partition.
Note 1: The Delete Partition Command is available in the AIT mode and only for an AIT mode cassette.
Note 2: The Indicated Partition Number value specifies the partition number ABOVE which partitions are to be
deleted. Consequently, the value cannot represent the last, open-ended partition on tape. The specified
partition itself is converted into an open-ended partition with its data contents preserved.
Note 3: Delete Partition is System area in the Active partition.
Examples :
Case 1 (with PRTH=0) ;
With the tape already loaded, and with partition 5 active, the Delete Partition command issued with the Indicated
partition Number set to 5 (the last partition) will be rejected with CHECK CONDITION (Illegal parameter). See Notes
2 and 3.

field in the Volume Information in MIC to 4. No tape motion will take place. The new last partition - partition 4 - will

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:
