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. AUTHORS
