Because of limitations in the ZIP utility used by Update Manager, the cumulative log bundle size cannot exceed 2GB, although the script seems to complete successfully.


Update Manager does not generate log bundle after the script is run.


  1. Log in to the computer on which Update Manager is installed, and open a Command Prompt window.
  2. Change to the directory where Update Manager is installed.
    The default location is C:\Program Files (x86)\VMware\Infrastructure\Update Manager.
  3. To run the script and exclude the vCenter Server logs enter the following command:
    cscript vum-support.wsf /n

    The /n option lets the script skip the vCenter Server support bundle and collect only the Update Manager log bundle.

  4. Press Enter.
    The Update Manager log bundle is generated as a ZIP package successfully.
