Shelf shutdown due to over-temperature
The maximum temperature of the shelf has been exceeded. Either a fan has failed, an obstruction is blocking the airflow, or the temperature of the room is too high.
Refer to the applicable hardware documentation for more information on the temperature specifications of the shelf and how it handles over-temperature conditions.
This condition is critical and has caused the shelf to shut down. Data access cannot be restored until the problem is resolved.
Recovery Steps
Are any fan failures being reported in the Problems area?
If yes, select the failure and use the associated recovery steps to replace the failed fan.
If no, remove any obstructions that may be blocking the storage array's air intakes or outlets. If no obstructions are found, correct any potential room cooling problems and then go to step 2.
Select Recheck to ensure the problem has been resolved.
