# scsi_satl
#
# Script to test compliance of SCSI commands on a SCSI to ATA
# Translation (SAT) Layer (SATL). This script was compiled using
# sat-r09.pdf found at www.t10.org .
# The scripts still seems to be valid for sat2r09.pdf .
# 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)
