Symptoms

Observed Symptoms

  • BMR Wizard UI is not opening at all after the machine is booted with the Avamar BMR WinPE ISO.
  • The WinPE command prompt is opened, however the Wizard does not appear.

 

Cause

Root Cause: Timestamp Limitation

The BMR Wizard UI contained a maximum timestamp limit set to 01.01.2021. After this date the wizard would not launch.

The limitation has been removed in a hotfix ISO for versions prior to 19.7 and later.

Example client version output confirming the fix:

% avtar –-version 
Version: 18.1.100-33_HF328844

Resolution

Deploy BMR HotFix ISO

Download the appropriate HotFix ISO for the Avamar version in use and deploy it to the target platform.

  1. Identify the Avamar version (e.g., 18.1.100-33, 19.2.100-155).
  2. Download the matching HotFix ISO from the Dell Support page.
  3. Deploy the ISO to the server following standard deployment procedures.
  4. Verify the client version after deployment by running the command avtar --version at a command prompt.
    % avtar –-version
    Version: 18.1.100-33_HF328844
  5. Refer to the Dell Avamar for Windows Servers User Guide page 17  for detailed ISO deployment and BMR execution steps.
