It is possible that you may have got DOA (Dead on Arrival) Part.

Try replacing the Controller 1 more time, if it still fails then you may need to isolate the issue to Midplane Chassis.

If this is not coverered under a warranty and if you can then you can follow:

Power off Hosts

Power Down MSA

Swap the Controllers ( A to Slot B and B to Slot A).

Power On the MSA.

If the Fault follows the controller then it is a Controller Failure (DOA) --- > Replace Controller Module.

If the Fault still remains on Controller A (which was originally Controller B) ---- Try replacing Midplane Chassis.
