Issue

  • Cluster acquisition is stuck in progress for hours

Cluster discovery failed. Rediscover the cluster after resolving the issue

Unable to add cluster datasource. This can occur if the clocks on the systems are not synchronized and the Active IQ Unified Manager HTTPS certificate start date is later than the date on the cluster, or if the cluster has reached the maximum number of EMS notification destinations.

  • Cluster acquisition fails, au.log:
