In the controller BIOS, LUN is enabled and seems to be working. At the controller POST both devices in the SuperLoader are recognized as address 8 and address 8 w/LUN 1. The controller host is address 7. After confirming all of the settings are correct, I am still unable to see the Medium Changer in the Device Manager.

The common cause for the OS to see only the tape drive and not the library happens when both are on the same SCSI ID but different LUNs and the controller is configured for LUN support disabled which is the default for many.
Check the controller documentation or go into the controller setup and make sure LUN support is enabled.
A SCSI ID is like an address on the bus, and a LUN is like an address at that ID.
Like an apartment building, all tenets have the same street address but a different apartment #.
