FAS 8080 Unexpected Reboots

mseufert

We are having an issue with one of our FAS 8080's, it's rebooting intermittently now for the past 48 hours. Have tried to power down, re-seat components and boots up fine, runs for a while and then will reboot on it's own again a few minutes later. Looking in the console log shows a number of items. Attached are the logs, any help would be greatly appreciated

what is the SP FW version?

 

did you rebooted the SP? if not.. try that and check if the system stays up for more than those few days reported.

Could be this: https://kb.netapp.com/Advice_and_Troubleshooting/Data_Storage_Systems/FAS_Systems/System_Rebooted_Due_to_L2_Watchdog_Reset

 

Unfortunately there could be several causes... I will try to find some and post here.

Not sure what SP FW version, but will look at updating it. And yes, we did reboot the SP. I'll keep you posted.
