IBM T200F Receive Diagnostic, Results Release Unit, Report Density, Support, Request Sense, Space

Table 110. Abort Condition Handling (continued)

Command	Abort Processing
RECEIVE DIAGNOSTIC	None.
RESULTS
RELEASE UNIT	The command completes.
REPORT DENSITY	None.
SUPPORT
REPORT LUNs	None.
REQUEST SENSE	Sense data is discarded.
RESERVE UNIT	The command completes.
REWIND	The command completes.
SEND DIAGNOSTIC	Vendor unique.
SPACE	The logical position is set back to that at the start of the
	operation unless the operation is past its ‘point of no return’,
	in which case the operation completes.
TEST UNIT READY	None.
VERIFY	The logical position is set to the next record boundary after
	the point where the verify was aborted.
WRITE	The data up to first record boundary in the current burst is
	written to buffer or tape, depending on Buffered Mode. Any
	subsequent data is discarded. If there is no record boundary
	in the current burst, the record is truncated to the amount of
	data transferred and written to buffer or tape, again
	depending on Buffered Mode.
WRITE BUFFER	If data transfer is completed, the command is completed;
	otherwise, no action is taken.
WRITE FILE MARKS	The command completes.

For drives with a SCSI interface, if a command other than INQUIRY, REPORT LUNs, REQUEST SENSE, or TEST UNIT READY is received after the abort but before the drive is ready to process the command, the drive attempts to disconnect and wait until the abort processing has completed before executing the command. If disconnects are not allowed, Busy status is returned. A TEST UNIT READY command reports with status immediately.

For drives with a Fibre Channel interface, an INQUIRY command returns the required data and gives Good status. A REQUEST SENSE command gives no sense. A TEST UNIT READY command reports with status immediately.
