If you believe that the ambient temperature might exceed the specified safe level for the array, consider stopping I/O and
then manually shutting down the array and its attached expansion shelves. That action avoids the possibility of a sudden,
unplanned array shutdown.
See Shut Down the Array Using the GUI on page 45.
If the external temperature in your environment is below the specified safe level for the array, you have verified that there is
ample air flow around the system, and you still get alert messages, contact HPE Support. See Support.
