Explanation: The targeted media was found in a drive differing from the targeted drive.
Requested media can be temporarily unavailable, which is normal. Also, media can remain unavailable until administrator or operator action is taken.
If the media is needed immediately, examine command output (if available), debug logs, and system logs for messages relating to the targeted media.
Check for conflicts between multiple applications using media in the robotic library. Check integrity of the drive and drive paths, so that media is not routinely left in other drives.
