sg_emc_trespass - change ownership of SCSI LUN from another Service-Processor to
] [ -V
sg_emc_trespass sends an EMC-specific Trespass Command to the DEVICE
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.
Arguments to long options are mandatory for short options as well.
- 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.
