NAME

6       sg_emc_trespass  -  change  ownership  of  SCSI  LUN  from another Ser‐
7       vice-Processor to this one
8

SYNOPSIS

10       sg_emc_trespass [-d] [-hr] [-s] [-V] DEVICE
11

DESCRIPTION

13       sg_emc_trespass sends an EMC-specific Trespass Command  to  the  DEVICE
14       with  the  selected  options. This Mode Select changes the ownership of
15       the LUN of the device from another Service-Processor  to  the  one  the
16       command was received on.
17

OPTIONS

19       Arguments to long options are mandatory for short options as well.
20
21       -d     outputs  some  extra debug information associated with executing
22              this command
23
24       -hr    Sets the 'Honor Reservation' bit in the  command.  If  set,  the
25              trespass will only succeed to change the ownership from the Peer
26              SP if the Peer SP does not have an outstanding SCSI  reservation
27              for the LUN. By default, the reservation state will be ignored.
28
29       -s     Send  the  short  version of the trespass command instead of the
30              long version. The short version is supported on the EMC  FC5300,
31              FC4500  and  FC4700.  The long version (default) is supported on
32              the CLARiiON CX and AX family arrays.
33
34       -V     print out version string then exit.
35
36       In the 2.4 series of Linux kernels the DEVICE must be  a  SCSI  generic
37       (sg)  device.  In the 2.6 series block devices (e.g. SCSI disks and DVD
38       drives) can also be specified. For example "sg_start 0  /dev/sda"  will
39       work in the 2.6 series kernels.
40

EXIT STATUS

42       The  exit  status of sg_emc_trespass is 0 when it is successful. Other‐
43       wise see the sg3_utils(8) man page.
