APIC

[husamabobakr]

Dear Cisco team,

                One of Customer is asking for following test scenario for NRFU

The customer wants to unplug the power Cables from all three APIC nodes instead of graceful Shutdown at each site and wants to check if it works fine after powering on.

Please confirm if Cisco supports such a scenario. If yes, we need confirmation that it works fine after such power failure. If no, then we need a strong enough recommendation (preferably supported by a published document by Cisco for best practices) to show to the Customer as a justification for not going forward with this test scenario for NRFU. “

Hi @husamabobakr,

What you ask is a very interesting scenario that does not generate impacts if the cluster is configured optimally. Once the controllers are down, both the thorns and the leaf will continue to work. The only disservice that you will have will be the impossibility of being able to make change or implementations as you will have down controller.

I link to you a similar thread where all the scenarios will be present with also reference links to the documents to be shown to the customer: All APIC Controllers in Fabric Go Down 

Regards.
