Re: RAID sets and cache batteries

That too is not true. I have had customers run years without a cache battery, they did so little with the thing they didn't care.

What could happen with some of the really old adapters is if the Load Source Disk was failed even though there was RAID you were still toast. That is no longer true.

I did have someone locally tell me recently, though, that if the cache
battery was toast AND the system was powered down, the system could not be
IPLed until the battery was replaced. (I elected to not test that
hypothesis.)

Not true. The RAID set will be fine. What goes is cache. Performance will
be awful at best.

Someone is saying that if the cache batteries die that breaks the RAID
set.
