Resolution
The library is trying to move some media, but can’t.
We made sure that no more tapes were loaded than the amount of slots the tape library had i.e. 10 slots = 10 tapes, as would also cause an issue.Drive one is attached to the NetVault Server and drive two is attached to a Smart Client that had a DSD license.
There was a problem with drive two whereby a tape was stuck and the hardware vendor advised that they could only replace the drive if a HP Diagnose Software was installed on the Smart Client. The problem only started to occur since the HP Diagnose Software was installed.
3] Remove the tape library from NetVault Device Management.
The following steps resolved the issue, as NetVault needs to have full control of the tape library i.e. no drivers/software installed, as this will interfere with the NetVault communication with the device:
1] Remove the HP Diagnose Tool Software from the Smart Client. If there are no uninstall steps supplied, then I would advise to contact your hardware vendor for the uninstall steps to make sure that the software is removed correctly and not causing an adverse effect.
2] Make screenshots of the tape library name and configurations within NetVault Device Management.
4] Power down the tape library, Smart Client (if you have the tape library/drive attached to one) and NetVault Server.
5] Power the tape library on and wait until fully booted and no error messages on the screen.
6] Power the Smart Client on (if you have the tape library/drive attached to one) and wait until fully booted.
7] Power the NetVault Server on and wait until fully booted.
8] Add the tape library to NetVault Device Management using the screenshots made earlier and make sure that the drives are added in the correct order i.e. compare the serial number in tape library configuration > Configuration tab and that it matches the serial numbers in the tape library web interface.
