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.
