About the consequences of sharing an off-site volume group across multiple robots
If profiles from multiple robots share both an off-site volume group and one or more off-site volume pools, your vault vendor returns a group of tapes (for a single Picking List for Vault report) that were ejected from multiple robots. The operator needs to identify which tapes should be injected into each of the robots. If mistakes are made identifying and injecting tapes, you can inject the incorrect media and possibly the incorrect number of media into your robots.
