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  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.

NAME

       sg_emc_trespass - Changes ownership of a LUN from another Service-Processor to this one.

SYNOPSIS

       sg_emc_trespass [-d] [-hr] [-s] [-V] DEVICE

DESCRIPTION

       sg_emc_trespass	sends  an EMC-specific Trespass Command to the DEVICE with the selected options. This Mode Select changes the ownership of
       the LUN of the device from another Service-Processor to the one the command was received on.

OPTIONS

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

       -d     outputs some extra debug information associated with executing this command

       -hr    Sets the 'Honor Reservation' bit in the command. If set, the trespass will only succeed to change the ownership from the Peer SP	if
	      the Peer SP does not have an outstanding SCSI reservation for the LUN. By default, the reservation state will be ignored.

       -s     Send the short version of the trespass command instead of the long version. The short version is supported on the EMC FC5300, FC4500
	      and FC4700. The long version (default) is supported on the CLARiiON CX and AX family arrays.

       -V     print out version string then exit.

       In the 2.4 series of Linux kernels the DEVICE must be a SCSI generic (sg) device. In the 2.6 series block devices (e.g. SCSI disks and  DVD
       drives) can also be specified. For example "sg_start 0 /dev/sda" will work in the 2.6 series kernels.

EXIT STATUS

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