Until recent my Intel RAID controller (SROMBSASMR) had a monthly occurrence of "BBU disabled: changing WB logical drives to WT", followed about 2 1/2 hours later by "Battery relearn complete".
Since a little over 2 weeks "BBU disabled" started appearing outside of this cycle in a steady pattern each 2 or 3 days*
I'm wondering what this means. Should I replace the battery? Is the controller about to fail?
For the record: I do know what the BBU disabled and relearn messages in themselves mean.
*to be precise 3 times spaced apart by 2 and 3 days, this cycle turn repeated every 8 days. I expect the next occurrence tomorrow in the early afternoon, roughly 2PM.
