Robotic status code 246
Message: Failed to find an available slot to inject to
Explanation: An attempt to inject a volume into a full library failed. This error should only occur when the library is full. Full means that all storage elements either contain media or have been assigned media that are currently mounted in a drive. Note that some libraries that support multiple media types restrict which type of media can be assigned to each storage element. In this case, this error might occur even if some of the storage elements in a library were not full. Since the empty storage elements may not match the media type for the media to inject, the library is full for this media type.
Recommended Action: Clear the media access port, then re-inventory the robot by doing a volume configuration update.
