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.
