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


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


       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.


       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.


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