Applies to

  • OnCommand Unified Manager 7.x -9.5 (OCUM)
  • Active IQ Unified Manager 9.6+ (AIQUM)

Issue

  • Suddenly cluster monitoring fails, or the cluster is not updated anymore
  • For a cluster that is being newly added, the addition works but the initial discovery fails
  • Issue is limited to one or more but does usually not affect all clusters
  • Events for the cluster indicate an Internal Error or Cannot update server as the failure reason.
  • ocumserver.log error for existing cluster:

ERROR [default task-41554] c.o.s.s.sessions (UpdateTaskExecuteSessionEJB.java:38) - Fail execute task com.netapp.oci.platform.originator.OriginatorUpdateTask: com.netapp.oci.server.UpdateTaskException [356-171-153]

  • ocumserver.log error for new cluster that is attempted for a fresh addition:
