Battery Nearing Expiration
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.
Important Notes
- The purpose of the batteries is to preserve cache data in the event of a power failure. Therefore, you should
replace the battery canister as soon as possible or risk losing cached data. Once the batteries reach their expiration
date, write caching is suspended until the battery canister is replaced and the batteries are fully charged.
- On some models, the battery canister can weigh up to 24 pounds (10.8 kilograms). Use both hands to remove and
replace the canister.
- The battery canister replacement procedure varies depending on the type of Storage Subsystem you have. The following
steps provide common battery replacement procedures. Consult the appropriate hardware manual if you need details
on locating and replacing the canister.
- Electrostatic charges can damage sensitive components. Use a grounding wrist strap or other anti-static precautions
before removing or handling components.
