NAME

       sg_emc_trespass - change ownership of SCSI 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.

NAME

       sg_rmsn - sends a SCSI READ MEDIA SERIAL NUMBER command

SYNOPSIS

       sg_rmsn [--help] [--raw] [--readonly] [--verbose] [--version] DEVICE

DESCRIPTION

       Send a SCSI READ MEDIA SERIAL NUMBER command to DEVICE and outputs the response.

       This  command is described in SPC-3 found at www.t10.org . It was originally added to SPC-3 in revision 11 (2003/2/12). It is not an manda-
       tory command and the author has not seen any SCSI devices that support it.

OPTIONS

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

       -h, --help
	      output the usage message then exit.

       -r, --raw
	      sends the serial number (if found) to stdout. This output may contain non-printable characters (e.g. the	serial	number	is  padded
	      with  NULLs  at  the  end  so its length is a multiple of 4). The default action is to print the serial number out in ASCII-HEX with
	      ASCII characters to the right. All error messages are sent to stderr.

       -R, --readonly
	      opens the DEVICE read-only rather than read-write which is the default. The Linux sg driver needs read-write  access  for  the  SCSI
	      READ MEDIA SERIAL NUMBER command but other access methods may require read-only access.

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

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

NOTES

       Device  identification  information is also found in a standard INQUIRY response and its VPD pages (see sg_vpd). The relevant VPD pages are
       the "device identification page" (VPD page 0x83) and the "unit serial number" page (VPD page 0x80).

       The MMC-4 command set for CD/DVD/HD-DVD/BD drives has a "media serial number" feature (0x109) [and a "logical unit serial number" feature].
       These can be viewed with sg_get_config.

EXIT STATUS

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