Delay Failover for 5 minutes on GTM wide IP with an irule

Thanks for the response...

basically, I want to just delay the failover from DC1 to DC2 for a particular virtual server.

On the LTM, there are 2 servers in the pool. They are in an active/standby state. Active server receives all connections unless the HM fails. However, the standby server, does not come online immediately (anywhere from 5secs to 5mins depending on the amount of data transferred between the failed server and the newly appointed active server). GTM on the other hand, see both servers are in a failed state and it sends traffic to DC2 because that's what its supposed to do.

The application owners want to delay this GTM failover, because they want the DC1 standby server to have enough time to come online (go active) and receive the connections. This could take 5secs to 5mins.

In the case DC1 fails completely, then the failover to DC2 would be acceptable.

I hope this is a better explanation. If this is unclear, I will post LTM/GTM configs
