Dell NetWorker 19.9 Administration Guide

Changing the hostname of a client

To change the hostname of a client, you must delete the Client resource, rename the directory with the client file index for the client, and then create a Client resource with the new hostname and the original client ID.

If you create the new Client resource but do not use the client ID of the original NetWorker host:

  • The NetWorker server considers the new hostname to be a new NetWorker host.
  • The NetWorker server assigns the new hostname a new client ID.
  • To recover data, you must perform a directed recovery from the original hostname to the new hostname.
  • You cannot perform a browsable recovery, only a save set recovery.

Use the nsrclientfix command to analyze the media database and identify client ID inconsistencies. To resolve client ID issues, use the nsrclientfix command to merge information about multiple clients in the media database and resource database into one client resource with the original client ID. The following KB articles on the Online Support website provide more information about using the nsrclientfix command:

  1. Record the client ID of the original Client resource:
    1. Enable diagnostic mode view by selecting View > Diagnostic Mode in the Administration window.
    2. In the Administration window, click Protection.
    3. In the expanded left pane, select Clients.
    4. In the right pane, right-click the Client resource and select Modify Client Properties.
      The Client Properties dialog box appears.
    5. Select the Globals (1 of 2) tab.
    6. Record the value in the Client ID attribute.
    7. Click Cancel.
  2. Delete the Client resource:
    1. Right-click the resource, and select Delete.
      A confirmation message appears.
    2. Click Yes.
  3. Stop all the NetWorker services on the NetWorker server.
  4. On the NetWorker server, rename the client file index directory for this client from old_client_name.domain.com to new_client_name.domain.com.
    The default location for the client file index is NetWorker_install_path\index\client_name.domain.com on Windows and /nsr/index/client_name.domain.com on UNIX/Linux.
  5. Restart the NetWorker services on the NetWorker server.
  6. Create a Client resource with the new hostname and the original client ID.
