recently, we only had one tape drive hooked up on a quantum scalar i40 tape library. the drive showed up in windows as a stand-alone and we installed the HP ultrium drivers for it.

so we assumed something was wrong because we weren’t seeing the medium changer listed in windows device manager. i installed qlogic sansurfer to identify the exact HBA we were using and installed the latest drivers. after rescan/reboot there was no change.

eventually i hooked up the 2nd tape drive after wondering if that was the problem and immediately the medium changer was present in windows. the HP driver auto-installed for the 2nd drive and i applied the quantum drivers to the medium changer.

will benny ever know the solution for this?
