3.2.1 ABORT TASK SET (06h)

The initiator sends this message to the SDLT tape drive to clear the current I/O process on the selected

logical unit. Buffered (cached) write operations are completed if possible. The drive goes directly to

the BUS FREE phase after successful receipt of this message. Current settings of MODE SELECT

parameters and reservations are not affected. Commands, data, and status for other initiators are not

affected.

An initiator may send this message to a logical unit that is not currently performing an operation for

the initiator. If the initiator does not select a logical unit, the drive enters the BUS FREE phase and no

commands, data, or status on the drive are affected.

If a WRITE command is in progress and STATUS has not been sent to the initiator when the drive

receives this message, the drive may write some or all of the data for the WRITE command to the

medium.
