Question : Error: Removable Storage did not mount the requested media. The operation was aborted.

The backup doesn't run in the last weeks on our Lotus Applicarion server and I see the error messsage:
"Removable Storage did not mount the requested media. The operation was aborted."

I put a DLT type into the server but if I open the Removal Storage Manager and check the Physical Location the system tells me that the drive is empty. Why?
"Drive 0  Compaq Value DLTtape (tm) DLT VS80 Drive " State empty

Answer : Error: Removable Storage did not mount the requested media. The operation was aborted.

even we had the same problem we had shut down the server for 5 min and started it..its working fine now...
