The above messages are SCSI messages from the tape library and supplied to NVBU i.e. is a problem outside of NVBU.
The tape library informs NVBU that there is a hardware issue when moving media.
To resolve this hardware issue please check/perform the following steps:
1] Make sure that the tape drives have been added to NVBU in the right order. Check the tape library web interface for the drive serial numbers and then compare them with the drives within NetVault Device Management (Right click a drive and select Configure > Configuration tab).
2] Make sure that the tape library and drives are on the latest Firmware versions. You can check the NetVault Backup Supported VTL Libraries Drives (2014-0415) compatibility guide for all the supported tape libraries, drives and firmware versions on the following link:
3] Check the tape library and FC/SCSI cards/cables for any hardware issues as well. Replace any defective hardware items.
Note 1: Whenever you replace/upgrade any tape library/drive and/or FC/SCSI cables, then you always have to perform the following steps to re-establish the SCSI Protocol Communication Channel (same protocol as FC), otherwise you will experience further backup/media/device issues:
A] Make a screenshot of the NVBU Device Management tape library name and configuration, so that when you re-add the device, you use the same name and settings.
B] Remove the tape library in NVBU Device Management.
C] Reboot the NetVault Server!
D] Re-add the tape library with the same name and settings as per the screenshots made earlier, as well as making sure the drives are added in the correct order.
Note 2: If your drive order are constantly changing and are using a FC network, then you will have to make sure that persistent bindings has been implemented.
