No. The RAID configuration is stored in non-volatile memory, which is not connected in any way to the battery-backed cache.
I have a 2950 with a dead RAID controller battery.  I have one person telling me that replacing the battery is a safe operation, and another saying that I'll have to rebuild the arrays.  Which is it?  Obviously, I'll make sure we have a good backup before doing anything.  Thank you in advance for your input, Mike Grammas
Will replacing RAID battery cause data loss?
