## NAME
       sg_emc_trespass - change ownership of SCSI LUN from another Service-Processor to this one

## SYNOPSIS
       **sg**___**emc**___**trespass** [_-d_] [_-hr_] [_-s_] [_-V_] _DEVICE_

## DESCRIPTION
       sg_emc_trespass  sends  an  EMC-specific Trespass Command to the _DEVICE_ with the selected op‐
       tions. This Mode Select changes the ownership of the LUN of  the  device  from  another  Ser‐
       vice-Processor to the one the command was received on.

## OPTIONS
       Arguments to long options are mandatory for short options as well.

### -d

### -hr
              ceed to change the ownership from the Peer SP if the Peer SP does  not  have  an  out‐
              standing  SCSI  reservation for the LUN. By default, the reservation state will be ig‐
              nored.

### -s
              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

       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.

## EXIT STATUS
       The exit status of sg_emc_trespass is 0 when it is successful. Otherwise see the [sg3_utils(8)](https://www.chedong.com/phpMan.php/man/sg3utils/8/markdown)
