APA Failover

[Chris Evans_5]

Hi there,

How do I configure APA just to fail over from one NIC to another and not do load balancing?

We are moving from one switch to two and all the examples I can find are only for load balancing which I am told is not supported under two switches.

Thanks
Chris

Hi Chris,

This document has the information your looking for:

http://www.docs.hp.com/hpux/onlinedocs/J4240-90016/J4240-90016.html

Search on Lan Monitor.

You can find an example in this document in the itrc knowledge base NETUXKBRC00005701.

Hope this helps,

Todd

That's great, Todd.

Just what I needed

Thanks

Hi,

Lan Monitor is great and works fine, but you can also flag your aggregate with distribution algorithm HOT_STANDBY to avoid load balancing, but give you fail over.

Details in the doc that Todd links.

That docs are more than enough.. still.

connect the
Configure it using sam, network, autoport aggregation .
Ensure that from each NIC cables r going to different switches to provide redundancy.

NIC spped and duplex settings also should match for both Network cards and connected switch ports..

main APA config files are given below..this looks like as below if u configure it for hostandby operation.
