I think I've figured out the mechanism that is causing Commvault to request new tapes, but I still can't quite figure out how to jump the final step and fix it. I'm hoping someone here has the knowledge to help me out.
Reading through the Commvault documentation, I noticed this section regarding appendable media:
"Mark Media Appendable
When this option is enabled, a media will be marked as Appendable when it is not available in the library and a new media will be used by the job. (If this option is not enabled, the media will be marked as Full.) Enabling this option ensures that the media in the library is fully utilized."
We have this option enabled. Problem is, looking at our media library, every single tape is listed as "unavailable", except for the four we currently have in our tape drives. So according to the documentation on appendable media, Commvault's behavior is to mark the media as appendable because it is not available, and requests a new media.
I looked around to see if I can somehow tell Commvault to mark these media as available even when they are not in the tape drive, but not having any luck so far. If I try to manually assign the location of a media, the only two options are "not applicable" and "not available".
Does anyone have any ideas here? Is there any way in Commvault to assign a default location for partially used media other than not available?
