Re: Quantum Error

The host backup application probably still has ownership of the library. You normally need to select to 'open door' or something similar to release ownership back to the library

Re: Quantum Error

You need to "unlock" the door.
In Backup Exec, go to the Devices tab.
Expand Robotic Libraries and locate the library.
Right click on the library, then select Unlock and wait for the job to complete.

Quantum superloader 3 drive error type

Hi Ulrike

I suspect that your backup software has "locked" the drive / library from the front panel.

This is why disconnecting / rebooting the library solves the issue.

If you are using backup exec or similar, try going to devices, selecting the library, right click and "unlock" before using the front panel buttons.
You could also use BUEX to do the tape moves for you instead of even touching the front panel.

Yes it needs repair, I suppose the tapes are fine them selfs so they should work fine in another one, you will have to service the tape drive, you can get another tape drive and the tapes should work.

I am getting a DRV PREV REMOVAL TYPE (46) message on display, every time I try and Inventory a tape or run Lable Media.

I have two of these Quantum SuperLoader 3 (with LTO3 drives) and one does keep giving me the same hassle. I haven't figured out how to fix this, but I've gotten past the error: disconnect the autoloader from the host computer (i.e. or stop rsm, mtx, or whatever controlling sofware you use), reboot the autoloader, get the tape out of the drive (e.g. move command from the autoloader's console or web interface), insert a cleaning tape (a few times), reconnect everything (i.e. start back up your controlling service).

Quantum superloader not showing in windows device manager

First off, I have to say that I have had nightmares with Quantum tape libraries. It is possible that they are still manufacturing lemons. I had one replaced 4-times and it still did not work!

Start troubleshooting by making sure that it is identified by the controller card it is connected to. You should see this during the server POST before Windows starts. If you don't see it there then Windows definitely won't see it. Send it to Quantum for service.

If the controller sees it then make sure that you are using the Backup Exec drivers. Never use the manufacturer's drivers with Backup Exec. Veritas, now Symantec, has a downloadable utility called the Device Driver Installation Wizard that will make sure you have the correct driver loaded.

I hope this helps.

SONY LIB-81 Error on LCD screen - Drive Information 51

I think this sounds like the drive is having a issue loading and moving the tape in slot 1.
AIT units are known for having this kind of problem.
Try a cleaning tape and then a new tape fresh out the wrapper for a test backup.

if it fails with a known good tape then its time to send it out for repair
