SPI$ABORT_COMMAND

Aborts execution of the outstanding SCSI command on a given connection.

Format

SPI$ABORT_COMMAND

Description

The SPI$ABORT_COMMAND macro aborts the outstanding SCSI command on

the connection speciﬁed in SCDRP$L_CDT. The SCSI port driver’s abort routine

sends the SCSI ABORT command to the target device.

Note

VAXstation 3520/3540 systems do not implement the abort-SCSI-

command function.

Inputs to the SPI$ABORT_COMMAND macro include the following:

Location Contents

R4 Address of the SPDT

R5 Address of the SCDRP

SCDRP$L_CDT Address of the SCDT

The port driver returns SS$_NORMAL status in R0, and preserves the contents

of R3, R4, and R5. The original SPI$SEND_COMMAND call completes with

SS$_ABORT status.
