What Caused the Problem?
The batteries in the battery canister are nearing their expiration date. The Recovery Guru Details area provides specific information you will need as you follow the recovery steps.
Caution
Do not perform these recovery steps if you have just turned on the Storage Subsystem or replaced a controller. During these two situations, the battery's self-test diagnostics take approximately 12 to 15 minutes to complete (depending on the controller type and whether the batteries were discharged). Until the diagnostic test is completed, you may see a Recovery Guru failure for batteries that are operational and fully charged.
Caution
Electrostatic charges can damage sensitive components. Use a grounding wrist strap or other anti-static precautions before removing or handling components.
Important Notes
Recovery Steps
1 | ![]() If you remove a battery while it is in a Battery Near 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). You have the following options:
