I have a customer who has set up 3 networks on each node of his DECsafe cluster. ( one FDDI and 2 ethernet). This set up is designed to spread the newtork load over 3 different networks. Each user connects to the same alias i.e. Network 1 connects to foo 1.1.1.1 Network 2 connects to foo 1.1.2.1 Network 1 connects to foo 1.1.3.1 The customer wants to be able to use the same alias ( foo) when the services are switched over to another node. I am sure that this is possible but I do not have a cluster to try it. I will be on site this Saturday doing it and I would rather know exactly how to do it before going on site. Can anyone help.

Hello Paul,
If you have three networks, you must have three alias names foo1, foo2
and foo3. It is not possible to associate three different addresses to
a single alias name.

If I understand .0 well, the foo definitions are different on each
network. Tricky! Wouldn't want to be responsible for maintaining them.
If the fail-over node also has three netwerk interfaces, I see no
reason why they could not be assigned those aliases too in case of a
failover. This can be tried manually by issuing:
ifconfig tu0 (or ln0, or fta0...) alias a.b.c.d
on the fail-over node, for each interface concerned. The same command
with -alias will remove them.
If this works it can be incorporated in a user script, along with a
ping check to find out if the aliases are defined anywhere else on the
network.
But perhaps I did not understand the question in .0 right.
