Hello,
You will need to address the issue that has caused a warning. Once the issue has been addressed the warning LED will return to a healthy green.
To determine the correct corrective steps that are needed you can review the events or logs to find the event which occurred. Using the Event Guide will help determine next steps.

If you can't find the component that is causing the events to occur, then please open a support case with HPE Support using the following web link, if the unit is under warranty: https://support.hpe.com/hpesc/public/home
Cheers,
