[Info-vax] HP HSV100 controller down due to failed batteries (Alpha ES47 - HP StorageWorks 3000)

The good news is the that the RX2800 i6 motherboard integral P410i RAID controller will fail soft to no BBWC if the FBWC supercapacitor decides to kak.  Replace the supercapacitor (offline) and you'll be back in the BBWC business.  The P400 and SA6402 Smartarray controllers that use batteries fail soft for write caching in the same manner.  I suspect the same holds true for the P800 but I don't have any experience with it.

Chances are all of the Compaq/HP/HPE Smartarray RAID controllers function in the same fashion in regards to this feature.
