Hi Marcio,

Try reseating the controller and see if it comes back up, it can be done with everything running on the other controller. Let us know if you have any other questions.

Hi Josh Cr,

Thanks for the answer.

You mean there's no preparation needed?

I can just pull the release lever to desengage the controller module (no need to disconnect I/O cables), wait a few seconds and insert the controller again and see if it comes up. Is it that simple? Sorry for my simple question, but I didn't find any documentation about the procedure. Is there any action that should be done before (or after) in Storage Manager?

Thanks.

Yes, that’s right. It is already in a failed state so it doesn’t need additional prep.

Hi DELL-Josh Cr,

Well, last week the survivor controller has failed too and the Storage Center became unresponsive. All services down. So, we went to a cold restart of the entire storage and after some time to come up, both controllers got to optimal state. I can't realize what  is going on. We'll try dig in the logs to find the possible cause. 

Thanks for your assistance,

What was the reason not to apply a single SCOS upgrade in the last 4 years?
