Quorum backup of IBM FlashSystem before battery replacement on IBM Cloud Pak System W3550

Troubleshooting


Problem

In rare cases, the battery replacement causes both batteries to go in an offline state at the same time and also cause data loss.
Description
Both IBM FlashSystem® 900 batteries going offline at the same time is a rare case that is seen with battery replacements, and in such situations, it needs to be recovered. IBM FlashSystem® support mitigated the situation from the firmware and from the backup quorum procedure.
