The StorageWorks MSA1000 isn't the brightest LED in the storage chandelier.

The LED will obviously light to indicate that a fault has arisen, and 
it'll light when you've not reviewed all of the faults.  When you have 
reviewed the faults, the LED will usually only light when you're 
rummaging that part of the error-review menu.  Based on what you're 
reporting, this all implies that one or more faults still lurk.

To clear the errors, the CLI is... useless.  You'll have to use the 
"game-pad" buttons to the right of the controller display.

You can press the left and right buttons simultaneously when you're in 
the error-review menu, and the specific selected error will be cleared. 
 I'd expect this can be used to clear the fault LED.  If it doesn't, 
there's probably something (still) wrong with the controller.  This 
much is documented.

You can also supposedly clear all of the errors with the use of the 
middle area within the four button "game-pad" to trigger the POST 
power-on self-test.  Scroll to the last entry in the error-review menu, 
and press the middle button, and slog through the self-test checks and 
prompts, and one of the self-test options available here is to clear 
all memory.  Press the up button to select YES and the right button to 
OK.  All errors should be cleared.  I've not encountered this 
documented, have not tried this path, and have never tried this on a 
running controller.  YMMV, etc.
