SCSI-Status Values
The SCSI status value from the CAM operation Execute SCSI I/O is put into the
appropriate field in the CAM structure and returned to the application. The application
should check the SCSI-status value even if the file-system error-code value returned is
0 or the FEOK literal (no error).
SCSI-status values are returned by the IOP exactly as they are received from the
IOAM. The IOAM firmware defines
0hFF
as a special SCSI-status value indicating that
no valid SCSI status is available from the device.
The SCSI-2 Standard defines bits 7, 6, and 0 of the SCSI-status value to be reserved.
The possible SCSI-status values are defined in the SCSI-2 Standard. See
.
