- # scsi_satl
- #
- # Script to test compliance of SCSI commands on a SCSI to ATA
- # Transaltion (SAT) Layer (SATL). This scripts was compiled using
- # sat-r09.pdf found at www.t10.org .
- # The vintage is SPC-3 and SPC-4 (see www.t10.org).
- #
- # Coverage:
- # Command SATL notes
- # -------------------------------------------------------
- # INQUIRY (standard)
- # INQUIRY (VPD: 0)
- # INQUIRY (VPD: 0x83) Device identification VPD page
- # INQUIRY (VPD: 0x89) ATA Information VPD page
- # REPORT LUNS SPC-3, SPC-4 (hardly mentioned in sat-r08c)
- # TEST UNIT READY
- # REQUEST SENSE
- # SEND DIAGNOSTIC default self test
- # MODE SENSE(10) draft unclear which mode pages, so ask for all
- # ATA PASS THROUGH(16) send IDENTIFY DEVICE command. Assume non-packet
- # device, if packet device add "-p" option
- #
- # This script uses utilities from sg3_utils package (version
- # 1.22 or later) and sdparm (version 0.99 or later)
