scsi_satl
SCSI_SATL(8) SG3_UTILS SCSI_SATL(8)
NAME
scsi_satl - check SCSI to ATA Translation (SAT) device support
SYNOPSIS
scsi_satl [--help] [--log] [--quiet] [--verbose] DEVICE
DESCRIPTION
This bash shell script calls several SCSI commands on the given DEVICE that is assumed to be an ATA device behind a SCSI to ATA Translation
(SAT) layer (SATL). The results of each test and a pass/fail count are output.
OPTIONS
Arguments to long options are mandatory for short options as well.
-h, --help
print out the usage message then exit.
-L, --log
the output to stderr (from each SCSI command executed) is appended to a file called 'scsi_satl.err' in the current working direc-
tory.
-q, --quiet
the amount of output is reduced and typically only the pass/fail count is output.
-v, --verbose
increase level or verbosity.
EXIT STATUS
The exit status of this script is the number of "bad" errors found. So an exit status of 0 means all mandatory SCSI commands worked as
expected.
