Handling Process
1. In VTL console navigation, right-click “physical resource” and choose “scan over again”.
2. Choose “find the new device” in the “appoint the adapter, SCSI ID and LUN area which need to scan” dialog box, then appoint the area of “SCSI ID”.
We advise the SCSI ID is 128.
3. Click “confirm”, begin to scan.
4. In VTL console navigation, choose “visual tape library system”, right-click “database” and choose “mirror>add”.
5. Choose the physical devices which need to add mirror in the “create visual tape library database mirror” dialog box.

Root Cause
There can be only one database mirror in VTL. If we delete the original database mirror, VTL console software hasn’t update in time, so it warns that we can’t add the new database mirror.
