I've talked to it and run the diags; looks good. It is incredibly noisy  
though with its intermittent recalibration grind.
Note that the console seems to do fine with the failed B-cache... until  
you boot.

I retrofitted the RD54, the VS was originally diskless. I had to run a  
cable to the I/O bulkhead from the controller, so apparently it never had  
a disk and may have indeed netbooted from a cluster node. I have no idea  
what's on that disk, and the neither did the previous owner. BOOT  
definitely fails, and the VS3200 console seems to lack any way of testing
