DDS-Format OAT Drive Troubleshooting
The DDS drive is replaced as an entire assembly, but before replacing it you must make sure
the problem is caused by a hardware failure. This means you must rule out problems caused
by
the environment or the tape media.
Use the following sequence to isolate DDS drive problems (see Figure 5-2).
1. Check the DDS drive status lights.
• If the lights indicate a high humidity fault, refer to Solving High Humidity Problems.
• If the lights indicate a media warning fault, refer to Solving Media Warning Problems.
2. Try cleaning the tape heads and see if the problem is solved.
3. Determine if
the problem is media-related by installing a new DDS cassette and retrying
the failed operation. If a cassette is jammed in the DDS drive tape mechanism, refer to
Removing Jammed Cassettes.
4. If the preceding steps have not solved the problem, replace the entire DDS drive.
5. Check system operation to make sure the problem is solved.
