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
-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.
