SIM 7.3 P4500 Lefthand in major status after discovery

Hi everyone,

I just deploy  a new HP SIM 7.3

After discovery my P4500 Lefthand are in major health status, just one is in green status.

I don't understand because they are in the same cluster and managed by the same CMC.

The CMC don't show me errors.

I already clear major events in SIM

I join a screenshot

Does anyone have an idea ?

Thanks !
