NAME
       scsi_logging_level - access Linux SCSI logging level information

SYNOPSIS
       scsi_logging_level [--all=LEV] [--create] [--error=LEV] [--get] [--help] [--highlevel=LEV] [--hlcomplete=LEV] [--hlqueue=LEV] [--ioctl=LEV]
       [--llcomplete=LEV] [--llqueue=LEV] [--lowlevel=LEV]  [--midlevel=LEV]  [--mlcomplete=LEV]  [--mlqueue=LEV]  [--scan=LEV]  [--set]  [--time-
       out=LEV] [--version]

DESCRIPTION
       This  bash shell script accesses the Linux SCSI subsystem logging level. The current values can be shown (e.g. with --get) or changed (e.g.
       with --set). Superuser permissions will typically be required to set the logging level.

       One of these options: --create, --get or --set is required. Only one can be given.

OPTIONS
       Arguments to long options are mandatory for short options as well.

       -a, --all=LEV
	      LEV is used for all SCSI_LOG fields.

       -c, --create
	      Options are parsed and placed in internal fields that are displayed but no logging levels are changed within the Linux kernel.

       -E, --error=LEV
	      LEV is placed in the SCSI_LOG_ERROR field.

       -g, --get
	      Fetches the current SCSI logging levels from the Linux kernel and displays them.

       -h, --help
	      print out the usage message then exit.

       -H, --highlevel=LEV
	      LEV is placed in the SCSI_LOG_HLQUEUE and SCSI_LOG_HLCOMPLETE fields.

       --hlcomplete=LEV
	      LEV is placed in the SCSI_LOG_HLCOMPLETE field.

       --hlqueue=LEV
	      LEV is placed in the SCSI_LOG_HLQUEUE field.

       -I, --ioctl=LEV
	      LEV is placed in the SCSI_LOG_IOCTL field.

       --llcomplete=LEV
	      LEV is placed in the SCSI_LOG_LLCOMPLETE field.

       --llqueue=LEV
	      LEV is placed in the SCSI_LOG_LLQUEUE field.

       -L, --lowlevel=LEV
	      LEV is placed in the SCSI_LOG_LLQUEUE and SCSI_LOG_LLCOMPLETE fields.

       -M, --midlevel=LEV
	      LEV is placed in the SCSI_LOG_MLQUEUE and SCSI_LOG_MLCOMPLETE fields.

       --mlcomplete=LEV
	      LEV is placed in the SCSI_LOG_MLCOMPLETE field.

       --mlqueue=LEV
	      LEV is placed in the SCSI_LOG_MLQUEUE field.

       -S, --scan=LEV
	      LEV is placed in the SCSI_LOG_SCAN field.

       -s, --set
	      Uses the fields specified in this command's options and attempts to apply them to the Linux SCSI subsystem logging levels. Typically
	      superuser permissions will be required to do this.

       -T, --timeout=LEV
	      LEV is placed in the SCSI_LOG_TIMEOUT field.

       -v, --version
	      Outputs the version information and then exits.

NOTES
       The --get and --set options access the /proc/sys/dev/scsi/logging_level pseudo file.

EXIT STATUS
       The exit status of this script is 0 when it is successful. Any other exit status indicates that an error has occurred.
