scsi_mandat
SCSI_MANDAT(8) SG3_UTILS SCSI_MANDAT(8)
NAME
scsi_mandat - check SCSI device support for mandatory commands
SYNOPSIS
scsi_mandat [--help] [--log] [--quiet] [--verbose] DEVICE
DESCRIPTION
This bash shell script calls several SCSI commands on the given DEVICE. These SCSI commands are considered mandatory (although that varies
a little depending on which standard/draft the DEVICE complies with). 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_mandat.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.
