Lost my tape library

I have 3 backup servers, my master and one media server is Windows 2008 R2 and running Netbackup 8.0. The other is running 2003 and NBU 7.5.0.7. This older server is only used for offsiting with the tape library. Last week, I had issues with this unit and network. After a few reboots, the server was back up on the network, but the library and tape drives were no longer recognized. I am at a loss as to why. They don't show up in device manager and not really sure where to go from here. I was in the process of bringing up a newer library and decommissioning the old library and server, but was not ready for that. Can anyone give me some guidance?

7.5
Windows Server 2003

    I've always found the key on these things to be establishing the device presence in the OS first, then you can get NBU to scan for and find the devices.

    So the question is: why does the OS not see any of the devices?

    How are they connected etc?

    Have you rebooted the library too?

      That's what I've determined. They are connected through Fiber, zoned correctly, connections are up. I rebooted the library and server and also bounced the fiber ports on the SAN switch. It's driving me crazy.

        Well, you're on really old versions (unsupported no less) of this part of this scenario.

        Can you stand up a replacement server (prefferably with a more modern OS) and get it connected to the devices?

        On the bright side, with tapes, it's not too painful to change ownership of them.

        If you can get a repalcement setup, just run a decommission against the old media server and have it switch ownership of its images to the new one, then you should be back in business.  (Assuming there's no diskpool on the old one involved and its just tape)

    Sound to me like the server lost it's connection with the tape library. 

    Try running the Netbackup command "scan"

    https://www.veritas.com/support/en_US/article.100025209

    If its return nothing, investigate SCSI/SAS/fibre channel connection to tape library. 

    If the scan command do return tape library and tape drives, then the old devices can be deleted in the NBU GUI. Use the device configuration wizard, to generate a new tape configuration.
