Unhealthy Component
-------------------
Component ID: Enclosure 1, Controller A

Even I restarted the controller A still the same.

Hi Murali,

You may remove and reseat the controller A in its slot to check whether it comes up. The controller will probably require a replacement if it fails to come up even after reseating it. Execute the command show system from a putty SSH session to controller B IP address  to confirm whether any components other than controller is in fault state.  Note: MSA 2040 is an end of support life product. You might need to consider migrating to newer version storage.

Hi Murali,

Please let us know whether removing and reseating the controller helped.
