I contacted the French IBM support but they are totally incompetent, so I ask my question here.
We have about 500 x3550M3 / M5015 / BBU. We have problem with BBU since the begining (defect, learning failed ...)
LSI released there is some months firmware version 12.12.0-0139 which contains a fix for our latest bug "SCGCQ00313883 - Battery continually stating Battery Yearly Deep Discharge Relearn Pending. Please Initiate a manual Relearn" (they also released 12.13.0-0154 recently)
IBM released the firmware 12.12.0-0133 and now 12.13.0-0153. But there is nothing in the IBM changelog about all fix from LSI of the 12.12.0-0139. Is IBM have took these fix into account ??
