outputs some extra debug information associated with executing this command
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.
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.
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.
