Takeover Occured on Controller

Hello All,

I am trying to figure out why my storage suddenly prompted a Takeover with the standby controller.

I cant find anything on the logs. Is there anything else to be checked?

Kate.  Thanks for posting your question first of all.

This seems like the standard answer, but calling support Toll Free: 1-877-364-6253http://www.nimblestorage.com/support/, or emailing them at support@nimblestorage.com will yield the best result.

They will likely request you to establish a secure tunnel to your system where they will issue commands in the CLI to determine the cause of the failover.

There are many reasons why a failover would occur, the most common being Firmware upgrades.

They should be able to help pinpoint exactly what caused this particular failover to occur.

Thank you

We have a CS700 that has experienced the controller take-over issue.

Nimble informed me that it will be resolved in an imminent firmware release. I think it will be in (and higher).

For the knowledge of everyone,

As per Nimble, this was a known issue and a fix was planned for the upcoming 2.2.5 OS release
