Any recent hardware changes on the MSA?
If you inspect both controllers, do you see any ambar or error LED?
Have you recently upgraded the firmware on it?
Does it show this alert since the beginning of time?
Have you restarted the controllers, one at a time, to see if the error clears?
Have you compared what is shown on the SMU is also shown on CLI?
can you execute this commands:
show alerts
show controllers
show frus
If the output shows the same errors and messages, I'd open a support case, as it might be a bug, or that the wrong controller was installed on the MSA.
Regards.
