We have a weekly full backup to tape with 4 tape drives. The tape policy is set to 4 streams with multiplexing of 5 streams. The "Start New Media" option under the schedule policy media tab is not checked.
The problem we are having is that Commvault never asks for the active media after it is done with it, even if the tape is not full. This occurs even when it is looking for the exact same stream number as the active media. E.g. it will ask for a new scratch of stream 2, even though there is an active stream 2 that was used previously.
This behaviour is new. About a year and a half ago it was working correctly, where it would request the active tapes instead of a new one. Unforunately, I was both new to the job and new to commvault at the time, so I wasn't really in the loop as to what might have changed. Recently I've been poring through all the settings to try and figure out how to fix this, and am coming up blank.
Does anyone have any ideas as to how to fix this?
