SCSI_LOGGING_LEVEL(8)						     SG3_UTILS						     SCSI_LOGGING_LEVEL(8)

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  Bourne  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.

NAME

       sg_read_buffer - send a SCSI READ BUFFER command

SYNOPSIS

       sg_read_buffer [--help] [--hex] [--id=ID] [--length=LEN] [--mode=MO] [--offset=OFF] [--raw] [--verbose] [--version] DEVICE

DESCRIPTION

       Sends  a  SCSI  READ  BUFFER  command  to the DEVICE, and if there is a response either decodes it, prints it in hexadecimal or sends it in
       binary to stdout. If a response is received for a "descriptor" mode then, in the absence of --hex and --raw, it is  decoded.  Response  for
       non-descriptor modes are output in hexadecimal unless the --raw option is given.

OPTIONS

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

       -h, --help
	      output the usage message then exit. If used multiple times also prints the mode names and their acronyms.

       -H, --hex
	      output the response in hexadecimal. When given twice the response is output in hex with the corresponding representation in ASCII to
	      the right of each line.

       -i, --id=ID
	      this option sets the buffer id field in the cdb. ID is a value between 0 (default) and 255 inclusive.

       -l, --length=LEN
	      where LEN is the length, in bytes, that is placed in the "allocation length" field in the cdb. The default value is 4  (bytes).  The
	      device may respond with less bytes.

       -m, --mode=MO
	      this option sets the mode field in the cdb. MO is a value between 0 (default) and 31 inclusive. Alternatively an abbreviation can be
	      given.  To list the available mode abbreviations use an invalid one (e.g. '--mode=xxx'). As an example, to  fetch  the  read  buffer
	      descriptor give '--mode=desc' .

       -o, --offset=OFF
	      this option sets the buffer offset field in the cdb. OFF is a value between 0 (default) and 2**24-1 . It is a byte offset.

       -r, --raw
	      if a response is received then it is sent in binary to stdout.

       -v, --verbose
	      increase the level of verbosity, (i.e. debug output).

       -V, --version
	      print the version string and then exit.

NOTES

       All  numbers  given  with options are assumed to be decimal.  Alternatively numerical values can be given in hexadecimal preceded by either
       "0x" or "0X" (or has a trailing "h" or "H").

EXIT STATUS

       The exit status of sg_read_buffer is 0 when it is successful. Otherwise see the sg3_utils(8) man page.
