SG_EMC_TRESPASS(8)                            SG3_UTILS                           SG_EMC_TRESPASS(8)



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     outputs some extra debug information associated with executing this command

       -hr    Sets  the  'Honor Reservation' bit in the command. If set, the trespass will only suc‐
              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     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.

       -V     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.

EXIT STATUS
       The exit status of sg_emc_trespass is 0 when it is successful. Otherwise see the sg3_utils(8)
       man page.
