Is there a software patch that will allow me to use a Sun-brand DLT4000 external SCSI-2 tape drive with a Netapp? I plugged one in, and the Netapp complained that "SUN DLT4000" wasn't a supported drive. Aren't these just Quantum mechanisms inside, but with Sun's name in the vendor string? I'd really rather not have to go out and buy all new drives...
