.TH SG_EMC_TRESPASS "8" "December 2012" "sg3_utils\-1.35" SG3_UTILS
.SH NAME
sg_emc_trespass \- change ownership of SCSI LUN from another
Service\-Processor to this one
.SH SYNOPSIS
.B sg_emc_trespass
[\fI\-d\fR] [\fI\-hr\fR] [\fI\-s\fR]
[\fI\-V\fR] \fIDEVICE\fR
.SH DESCRIPTION
.\" Add any additional description here
.PP
sg_emc_trespass sends an EMC\-specific Trespass Command to the \fIDEVICE\fR
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.
.SH OPTIONS
Arguments to long options are mandatory for short options as well.
.TP
\fB\-d\fR
outputs some extra debug information associated with executing this command
.TP
\fB\-hr\fR
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.
.TP
\fB\-s\fR
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.
.TP
\fB\-V\fR
print out version string then exit.
.PP
In the 2.4 series of Linux kernels the \fIDEVICE\fR 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.
.SH EXIT STATUS
The exit status of sg_emc_trespass is 0 when it is successful. Otherwise see
the sg3_utils(8) man page.
