Symptoms

  • The NetWorker Web User Interface (NWUI) server package is installed on a clustered system.
  • NWUI services intermittently fail to start.
  • Unexpected authentication errors appear when trying to access or log in to NWUI.
  • NWUI produces unexpected errors and warnings when performing admin tasks within the user interface.
  • There are no details in the NetWorker Cluster Integration Guide regarding configuring NWUI in a clustered environment.

Cause

The NetWorker Web User Interface (NWUI), and NetWorker Management Console (NMC) are not supported on cluster installations. The NetWorker Cluster Integration Guide states the following:

  • NMC and NWUI should always be used as standalone applications. Since NMC or NWUI is not cluster-aware or high available, therefore it has to be installed on the noncluster node.
  • NMC or NWUI should be configured with the cluster IP as authentication server IP.

NetWorker documentation is available through: Support for NetWorker | Manuals & Documents (You must sign in with your Dell support account). 

Resolution

The NetWorker Web User Interface (NWUI) server and NetWorker Management Console (NMC) server must be installed on a separate standalone server.
