Which initiator OS sent this command to SCST ? This is a SMART READ DATA command embedded in an ATA PASS-THROUGH command. The SMART READ DATA command returns 512 bytes but in the ATA PASS-THROUGH header the T_LENGTH field is zero (no data). I think that field should have been set to two (transfer length specified in the SECTOR_COUNT field). Bart. |

Windows 7 x64. If it's a SMART command then it's ok to ignore yes? Could have been one of the SMART utils that I ran coincidentally during the session.

If you don't need the SMART data at the initiator side then I think it is safe to ignore these warnings. On the other hand, it's probably not that hard to modify get_cdb_info_apt() such that it sets t_length and t_dir for SMART commands that communicate a data buffer between initiator and target.
