The manner in which a dynamic VIPA IP address defined by a VIPARANGE statement, should be moved to another stack. A value of nonDisruptive(1) means that this DVIPA can be moved to another stack as soon as the other stack requests ownership of the DVIPA by creating the same DVIPA via a subsequent BIND or SIOCSVIPA IOCTL. Any existing connections on this stack will be maintained by the new owning stack until the connections are closed. All new connection requests will be directed to the new stack. A value of disruptive(2) means that one of two different behaviors will occur: - In the case of a subsequent BIND by an application on another stack, no movement of the DVIPA will occur the second application will presumably be disrupted because the BIND fails. (The first application is unaware that another BIND occurred.) - In the case of a subsequent SIOCSVIPA IOCTL, the DVIPA will move to another stack but connections to the DVIPA on this stack will be broken.
