When configuring the VSA agent in CommVault, you get this error:
Please Configure Virtual Machine(s) in the contents tab to be backed up
This can happen because you have no machines set to be backed up. Click the Contents tab and add some virtual machines. If you are trying to remove all virtual machines from the backup, then you get the Please Configure Virtual Machine(s) because CommVault hates it’s customers and punishes them with an unnecessarily convoluted and generally poor user interface. In this case, you have to delete the job or configure some VMs to be backed up and disable the job. Alternatively, it might be worth trying to use the installed client to configure the job, instead of the web client (If that works, please let me know).
