Supported SCSI Messages
This section describes the messages outlined in
Table 3-1
.
3.2.1 ABORT (06h)
The initiator sends this message to the target to clear the current I/O process on the selected tape drive.
On buffered (cached) write operations, the tape drive attempts to complete the command, if possible.
The tape drive goes directly to the BUS FREE phase after it successfully receives this message. The
message has no effect on the current settings of the MODE SELECT parameters and reservations. It
also has no effect on commands, data, and status for other initiators.
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 tape drive enters BUS FREE phase and no
commands, data, or status on the drive are affected.
