Error: “Failed: Exception has been thrown by the target of an invocation” when Installing a VRA

Viewed 110 times


An administrator may experience a VRA install failure with an error regarding exception being thrown by the target.

Root Cause

Either the administrator is installing the VRA without the host root credentials or FIPS is enabled.


When installing a new VRA on a host, the installation might fail with the following:

Failed: Exception has been thrown by the target of an invocation.


To workaround this issue, follow the steps below:

  1. Install the VRA with the host root credentials included in the VRA Install Dialog window.

  2. If the issue still persists, please follow these instructions to disable FIPS on the ZVM where the VRA installs are being attempted.

  3. Restart the ZVM server.

  4. Deploy the VRA.

  5. Once complete, FIPs can be reenabled.
