SCSI returns are 32 bit numbers with definitions in include/scsi/scsi.h
going (from lowest to highest)

     1. status byte: the status return code from the command if
        successfully executed
     2. message byte: now misnamed, message is SPI specific, what it
        means is task status interlaced with possible SPI message
        responses.
     3. host byte: these are the DID_ codes, specific error codes
        returned by drivers.
     4. driver byte: Additional qualification of the error in host byte

In your case, it's showing DID_ERROR.
