How to add an IP alias with UCX much the way you would

[Tim Oakley]

The UCX command 'set interface/clus' allows multiple VMS cluster nodes
to share a 'cluster' ip adress, however it does not work the same as a
DECnet alias where a semblance of load balancing is involved. Instead a
cluster alias results in one of the named servers dealing with all IP
traffic directed to the alias adress. The machine which 'holds' the
adress is called the 'impersonator' in UCX speak. If the current
'impersonator' is shutdown or crashes then one of the other configured
nodes takes over as impersonator automatically without intervention from
support folks. 

Very fault tolerant but unfortunately no concept of load sharing.
