Virtual IP Address...

Genaro Montemayor — Tue, 21 Dec 1999 23:32:24 GMT

I'm working on a Full Time Cluster Configuration with 2 servers. In order to
start/stop services, I need to assign 2 IP Addresses to the same interface
(lanX). How can I do it? Any idea would be appreciated.

What OS are you using?
What do you mean by a clustering solution? MC/ServiceGuard?

without more information he question is not easy to answer.
For HP-UX 11.x the ifconfig command allows this, do a man ifconfig.
For 10.20, you need the ifalias patch

If you have a Physical interface and two logical interfaces (virtual IP's) in
HP-UX 11 you can do something like

ifconfig lan0:0 inet 20.3.3.3
ifconfig lan0:1 inet 20.4.4.4

Don't forget to make the changes in /etc/rc.config.d/netconf

There is also a similar posting a little while back to this forum have a look
at that.

I have HP-UX 10.20 with 2 K370 boxes. The product is "Full Time Cluster" from
Legato.
