You can only import and export data between a physical tape device and a virtual 
tape device of the same type, using physical and virtual media of the same 
capacity. 

2. If dissimilar physical and virtual devices or media are being used, stop here.

Correct the condition, and retry the import/export job.

3. If physical and virtual devices are identical or if making them so does not solve

the problem, see if compressed data is being imported/exported.

4. If compressed data is being imported/exported, make sure that virtual and

physical media have the same uncompressed capacity.

Import/export operations fail if the target media does not have enough capacity to 
accommodate decompressed data. 

5. If compression is not an issue, see “The export/import job is not complete” on

page 238.

Case: The export/import job is not complete

1. If dissimilar media capacity is not the problem, make sure that the job is not still

running. In the VTL console, select the Import/Export Queue, and search for
related export/import jobs.

2. If a related job is found, the job is not yet complete. Stop here, and recheck it later.

Jobs are only listed in the queue while active, so listed jobs are still running. 

3. If related jobs are not listed in the queue or if the problem persists after the job

completes, use the VTL console to examine the Event Log for failure messages.

4. If failure messages are found, stop here, correct the error condition(s), and retry

the import/export job.

5. If the problem persists, see “Virtual tape barcodes duplicate physical tape

barcodes” on page 238.

Case: Virtual tape barcodes duplicate physical tape barcodes

1. If export/import problems persist, make sure that virtual and physical tapes each

have their own, unique barcodes. Use the VTL console to Inventory the physical
library, and check the results against the virtual tapes.

2. If duplicates are found, stop here. Correct the situation, and retry the

import/export operation.

3. Otherwise, see “A physical tape library or device is not ready” on page 238.

Case: A physical tape library or device is not ready

1. Check the status of physical tape drives.
