NetApp Storage Array
Usually this is due to a failed power supply. This can be caused by a power outage as well or a loose power supply cord. Check all of these things first. If everything looks good and there were no power outages, it is best to generate a support log bundle from the array. This can be generated either using the SANtricity user interface or by using an SMcli command. Details on how to generate a log bundle can be found in KB Article 210792, "How to generate a support bundle for Dell MD3860 or NetApp attached storage"
Once the log bundle has been generated, open a support case with Broadcom support for further analysis and possible RMA of a failed power supply.
