Although the script seems to complete successfully, an Update Manager log bundle might not be generated. Because of limitations in the ZIP utility that Update Manager uses, the cumulative log bundle size cannot exceed 2 GB. If the log exceeds 2 GB, the operation might fail.


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


  1. Log in to the machine where Update Manager runs, 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 to 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.
