A battery is nearing the end of its useful life. The Recovery Guru Details area provides specific information you will need as you follow the recovery steps.
Caution: Electrostatic charges can damage sensitive components. Always use proper antistatic protection when handling components. Touching components without using a proper ground may damage the equipment.
You have the following options for resolving this problem (more details will be provided in the Recovery Steps):
Caution: Risk of Data Loss. If you remove a battery while it is in a Battery Nearing Expiration state and write caching is enabled on a logical drive, you risk the chance of losing cached data if power to the storage subsystem fails. If power fails before the storage subsystem can detect the removed battery and write all cached data to the disks, you will lose cached data. Typically, it takes approximately 2 minutes to write all cached data (with a maximum of 10 minutes).
Refer to the 'Component requiring service' field in the Details area to determine which Recovery Steps you need to complete.
If... | Then... |
The component requiring service is the battery | Go to "Recovery Steps for a Directly-Accessible Battery." |
The component requiring service is the controller that contains the battery | Go to "Recovery Steps for a Battery Inside a Controller." |
