The trespass mode for this node.
Every iSCSI target represents one or more port(s) on the
FC target (fc2ScsiPortFCAddrListIndex).
If this object is 'true', the node instructs the FC node
to present all LUN I/O requests to secondary port
(fcSecondaryAddress) if the primary port (fcAddress) is
down.
Note that this object is valid only if fc2IscsiNodeRole
is 'targetTypeNode'.
