SolutionThese and other similar IP tasks are often handled with a front-end network processing device; with a typical high-end network router.
OpenVMS does offer IP address failover (IP failSAFE), and does offer full cluster alias capabilities, and does offer load balancing via loadbroker and such.
Within a cluster configuration, every IP link around can be active. That written, OpenVMS does not offer link aggregation.

Re: VMS does network load balancing?
If the later, we use Load balancing with the Multinet stack from Process Software. Multinet computes the load rating in a fashion that is very similar to how how LAT would compute ratings. Most of the rating is based on CPU utilization on the node.
From what I have seen most of the front end load balancers either round-robin on a connection by connection basis or use PING response time to determine load on a node.
The round-robin method does not take the exisitng load on the server into account. The problem with the ping method is that in general the response time from a PING won't very significantly until the server is under high i.e. 95% CPU load.
