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


       sg_emc_trespass [-d] [-hr] [-s] [-V] <sg_device>


       sg_emc_trespass sends an EMC-specific Trespass  Command  to  the  given
       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.

       -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 given device must be a SCSI
       generic (sg) device. In the 2.6 series block devices  (e.g.  disks  and
       SCSI  DVDs)  can  also  be specified. For example "sg_start 0 /dev/sda"
       will work in the 2.6 series kernels.
