The RAID/NVRAM battery on a BlueArc Mercury storage host is located in the front of the storage head, and can be replaced without down time. From what I can gather, after battery change, I have to enter its Linux mode, and enter "something".
Does anyone know what "this something" is?
Update
How to change a battery is not documented in the manuals, as it is normally a task that you pay a certified BlueArc engineer for. So how to do it is not documented in anything that is available to the owner.
