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
