Ontap Behaviour after power outage - prevent auto-boot

ac_ac — Thu, 26 Oct 2023 22:48:11 GMT

Hello, we have had a couple of complete power outages recently and would like to set our Ontap nodes to NOT boot after power gets restored. This is so we can power up everything in the correct order to prevent application tantrums.

Can it be set to not power on at all? or pause during boot and someone needs to login to the SP and hit continue?

I've started to read the doco, but haven't found anything so far.

Cheers AC

Power outage reasons if you're wondering:

both during electrical maintenance, even though there's supposed to be redundancy. One was a failure in the fire suppression power board and the other was a UPS battery failure and it didn't switch back to bypass. Unlucky situations, but at least they were discovered during maintenance and not when there was an actual DR event.

Ok the title is fixed. The URL will redirect to a better question that should come up when searching now.

Thanks Paul.

Will changing this option stop the nodes from booting during an ontap upgrade?

Is there an option to only do this after a power-failure? Like in Dell server bios Last Power State Behavior.
