Network failover without MCSG?

Alexandre_12 — Mon, 26 Apr 2004 16:10:23 GMT

Hi people,

I hope that's not a "too silly to be answered" question, but there's a way to build a network failover solution without the use of MC Service Guard or any other clustering solution?
I mean is there a configuration in the HP-UX itself that could provide simple automatic failover in case one network card fails?

HP-UX 11i is Op. Syst. and I have 2 quad. NICs.

Thanks already!

Check the above link - you can use HP Auto Port Aggregation.

Hi Alexandre,
No. You cannot do it with the base HP-UX.

You need to use either MC/SG or HP-APA.

Hi,

HP UX itself does not give this facility. You have to use HP product called APA (Auto Port Aggergation), It's a price product from HP which give you failover as well as truncking of NIC.

Or

You can write script which will monitor your LAn card in case of problem it should unconfigure that card and configure other card with same ip address.

Bingo! you can make it by the APA.

Download document of the APA from http://docs.hp.com

Strangely, I have a script that does this.

It was actually written to restart process that die but is flexible enough to do failover. I have used it for failing over Linux web servers (and taking them back after) but as it's perl, it will work with hpux too. I attach a tar file of the script which contains an example config file and a tkperl front end manager which you don't need but as I just wrote it, and it's my first go at tkperl, I thought I'd include. I also attach a short note on how to make it do a failover.
