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. AUTHORS
