L2 Cache Parity error on eva3000

Tonight one of our eva3000 had a controller restart with Controller Termination Event Log entry: 04273914 L2 Cache Parity error.
After reboot it started to work properly but what happened?

Some other errors connected:

Re: L2 Cache Parity error on eva3000

Hi Daniel,

This could happen due to any Host port error for which log analysis would be required.

But, one occurrence of TC 04273914 does not require controller replacement. If another termination(with same termination code) occurs within 3 months of time for the same controller then replace it. Shut down and Restart of controller is recommended for the termination

Also suggested to Upgrade the latest VCS code that is version: 3110 for active passive and 4100 for active active firmware.

Hope this helps,

Re: L2 Cache Parity error on eva3000

The errors you see there, are they close to the same second? Do you see anything going on before the #3966470 besides the disk timeout? Disk timeout may very well have been because of the controller restarting - and not what caused the controller restart :)

Cache parity errors are quite rare and seldom seen again after the one occurance - but the controller restarts to recover from the error.

Do you see any errors now in CV?

After restart all is OK, it's been 16h since then

Some more logs attached. Event log is at the bottom

Well the logs you posted don't go back long enough to say - to me it looks like they are all from the restart. I don't have access to the hp eva log reader tool anymore so can't help you with that.
