Master Server not seeing Robot after configuration

 This is an Oracle/ Sun StorageTek SL150 with two tape drives. We’re running NBU 7.5 on Windows Server 2008 R2. This was working just fine for 2-3 months without issue. We needed to add in new tapes and this is how events occurred:

1. When tape drive was setup Admin password was set but not documented
2. Needed to add in more tapes
3. Could not take tape drive offline - Pulled out tape drive anyway and added tapes (bad idea, I know..)
4. Rebooted tape drive/ server – inventoried robot
5. Decided to reset tape drive since we couldn’t manage the tape drive properly without an admin password
6. Held down both locator buttons and reset tape drive
7. Server was already shut down – shut down tape drive
8. Turned on tape drive – reconfigured with the exact same settings (same name, ip, etc)
9. Rebooted tape drive all the way up to operational state
10. Turned on server – was able to see the new tapes and inventory robot
11. Jobs failed that night with error code or job status of 2009 – I think
12. Decided to remove robot from NBU and re- add it in like I’ve done before with the older tape drives.
    1. Remove from NBU and Device drivers
    2. Shut down server
    3. Shut down tape drive
    4. Restart tape drive – all the way up to operational state
    5. Restart server
13. Installed drivers for Tape drive (Hewlett Packard LTO Ultrium-5 drive x4)
14. Could not find drivers for Medium Changer Devices that automatically installed– then found Hewlett Packard 1x8 G2 autoloader (x64 based) x2 and installed it manually
15. Cannot reconfigure – The robot shows up as un-configured and unknown.
16. It allows me to “Configure Storage Devices” but then only shows tape drives and not the robot once finished

I don’t know what to do from here. I’m not doing anything different from when we originally got this tape drive working and I don’t know why it is seeing the drives and not seeing the robot.

Any thoughts? I don’t know what else I could try.

Thank you!
