CSM Sorry server/Backup serverfarm/HTTP redirect

Hi, I have tried to configure the backup serverfarm on CSM to provide sorry server service for my primary serverfarm. Following are the configuration I had:

serverfarm TT

real 10.0.0.1

inservice

real 10.0.0.2

inservice

serverfarm SorryTT

real 20.0.0.1

inservice

vserver VTT

virtual 200.0.0.1 tcp www

serverfarm TT backup SorryTT

inservice

I expected when all of the real servers in serverfarm TT went down, all of the http traffic to 200.0.0.1 will be redirect to the real server 20.0.0.1 in Serverfarm SorryTT. But looks like it's not working.

Or is there anyway we can configure the http redirect when all of the server in one serverfarm are all dead? The Cisco's configuration guide is not very helpful.

Thanks.

Re: CSM Sorry server/Backup serverfarm/HTTP redirect

Whenever the primary serverfarm is down (all its vservers have failed or are down), the CSM will start using the sorry serverfarm servers to serve requests to the vserver. The configuration looks fine to me. Are you receiving any error messages ?

Can you enable debug messages and try to see what the problem could be.

new connection will use the backup serverfarm but existing active connection will try to use the old serverfarm.

You need to configure a 'failaction [purge|reassign]' to change this behavior.
