Before you replace a DE6000H battery, review the requirements and considerations.

Each controller canister includes a battery that preserves cached data if the AC power fails. To protect your data, you must replace a failed battery as soon as possible.

Recovery Guru alerts

If the Recovery Guru in ThinkSystem System Manager reports one of following statuses, you must replace the affected battery:

  • Battery Failed

From ThinkSystem System Manager, review the details in the Recovery Guru to confirm that there is an issue with a battery and to ensure no other items must be addressed first.
