I have a x3650 M3 server with a M5015 Raid controller. I want to configure RAID5 with "Write Back with BBU" in the Megaraid Bios Conig Util, but it is not possible,
Error: "There is no cache battery installed or the battery charge is low or the battery is failed or the battery in running through re-learn cycle. In this case the writepolicy will switch to Write Through"
As you can see battery is installed, and the "Design Charge Capacity remaining" is 87%.
