My experience is only with "growing" a LUN, but from memory the command is chvg and the flag is either -g or -G.

sg_emc_trespass
SG_EMC_TRESPASS(8) SG3_UTILS SG_EMC_TRESPASS(8)
NAME
sg_emc_trespass - Changes ownership of a 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 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.
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 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.
-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.
