Same problem with SAS TS3100.
I can't see autoloader in device manager.
But there nothing to configure, in device settings i may change only library type of access(random & sequental, by default is random).
I was tryed to change type of access(with all steps including reloading TS3100 and server), but nothing happens, Device manager always see attached device like IBM 3580-TD4 sequental drive.
I was tryed to change port, and it stil IBM 3580-TD4 sequental drive.
I was tryed use IBM drivers(it was instal system device:PCI Tape Changer, and Tape device:IBM TD3580).
I was tryed fully uninstal BackupExec from server(first full uninstal IBM drivers, then full uninstal symantec drivers, then uninstal BackupExec.) and install it again with latest support drivers package from link provided below, and nothing changed. In device manager i see only: IBM 3580-TD4 sequental drive and PCI tape changer with yellow tringle(drivers not installed correctly).
Somebody have any ideas?
