APA error message

Jomadar — Mon, 14 Jun 2004 13:38:41 GMT

Dear experts,

i configured Auto-Port Aggregation for Hot Standby. Since with SAM did not succeed, did manually. After some attempts it does work seemingly perfectly, (unplugged one of 2 cables - no matter which one - applications did not feel anything) but i got error message pasted below. Do you have idea what is the reason? Is it safe to run system with it?
Thanks for your help

you may want to make sure that the "0" PPA/interface is in the same duplex mode as the other interface. Also, make sure that lan0 is not ifconfig'ed before the APA and you are only doing ifconfig on lan900

Thank you Rick.
In netconf file i set lan[0] but if i skip this unix dont get ip. How should netconf look like in this Hot Standby case?

I think you may need to read the APA manuals a bit more closely :) http://docs.hp.com/

In particular, APA produces a virtual (not to be confused with VLAN) interface which knows how to failover/balance between some number of physical interfaces. It is that virtual interface you ifconfig, not the underlying physical ones.

So, in your netconf file, you would have an entry for lan900, not lan0.

ooops im afraid i have read too many and got confused... i was rather in hurry
This was written:"To preserve the IP address across reboots you need to add the IP address for the primary port to /etc/rc.config.d/netconf"
ok, i'll try to set netconf as soon as i get the chance... it is productive now and not allowed to touch.
Thanks for your help
