nimble Controller B rebooted unexpectedly

[Cloudcover]

We have been getting alerts that our secondary controller B has been rebooting unexpectedly on our Nimble. Looking at the logs this has been happening almost daily for approximately a month now.

Event logs show the hardware warning unexpected reboot of Nimble Controller B but do not provide more information as to why the controller rebooted unexpectedly

Is there a way to figure out the reboot aside from the event logs?

Hi,

Controller B on Nimble array AF-213000 has been rebooting due to a memory error on the controller. The solution is to replace Controller B.

However the support contract for this array has expired.  Kindly have the support contract renewed. Once that is done contact Nimble Support to arrange for a controller replacement.

Below is the Nimble support contact details:-
