In UCS version 3.2(1d) we have a bug as below, do we have any more info of how to clear the alert, if any.

It looks like bug: CSCur03134
I too encountered this fault. Upon reboot of secondary FI(that had the alert) alert cleared from the UCS Manager. Later during the day the issue reappeared.
Replacing the FI eventually resolved the issue.
