recently i have configured dell vrtx server for our client. but there is a issue with CMC card.

in the cmc login interface, display some critical alert called  "vrtx chassis management controller (cmc) redundancy is lost". both cmc firmware updated to latest version (2.23).  one cmc card in active state and other one is in standby state. but still display that alert. i need know this is error or just a alert.

so please help me to resolve this issue.
