IncompleteDiscovery

NodeCluster

Indicates that Server Manager was not able to associate this cluster with a host or hostname that has been discovered through IP. This problem could occur for one of two reasons:

  • The host entity was never discovered by the IP Availability Manager.

  • The host entity was discovered by the IP Availability Manager with a different hostname from the hostname known by Microsoft cluster.

    Note:

    If the host entity was not discovered, manually discover the entity. If the host entity was discovered under another name, follow the appropriate procedure described in “Configure IP Manager to discover cluster hosts using cluster node name” on page 317.
