Issue

When adding a cluster data source to Unified Manager, an error will occur indicating that clocks on the systems are no synchronized and that the Unified Manager HTTPS certificate start date is later than the date on the cluster, or the cluster has reached the maximum number of EMS notification destinations. Attention should be directed to the following logs:

ocumserver.log

ocum-error.log

server_mega.log

The following may be messages that will be seen in these logs:
