The server queried the drive's encryption capability, and the query failed or the query showed that the drive does not have encryption capabilities.
The mount operation fails.
If this message occurs on a scratch mount and drive encryption has not been utilized yet, you can turn drive encryption off by updating the DRIVEENCRYPTION parameter on the device class. Otherwise, verify your hardware configuration. First, verify that all the drives in this logical library support drive encryption. Second, verify that the device driver controlling all of the drives in this library also supports drive encryption. If both the drives and the device driver support drive encryption, call your drive hardware support.
