I installed an external HP StorageWorks Ultrium 448 on my Netware 6.5 sp 7 server and the device is recognized at bootup and recognized by Netware, but it's deactiavted. When I attempt to activate the device, I receive the following error:

Error activating device ( Please check media). MM_ERROR(7)

Everything appears to be working correctly, but I can't get the device to activate. Any assistance is greatly appreciated!
