Hello We have a problem with a Netapp filler. Sometimes it doesn't send Autosupports. Service processor and controller management can't ping. We noticed that after controller restart everything returns to normal. Unfortunately controllers after restart can't boot up, it is necesseary to pull them off manually from the chassis. Then they are starting to boot because service processor is also inaccessible. Restart of service processor doesn't cause it respond for ping. We also don't have any trouble with filler in Poland, so I think it is not a network settings problem. Maybe it's a problem with a firmware. We can't add any log because we don't have any access to service processor.
