I am trying to install an HP StorageWorks DAT40 Tape drive at SC0 5.0.7. The tape drive is not functional.

When I run #sconf -v this is what I get;

Sdsk ad160 0 0 0 0
Sdsk ad160 0 0 1 0
Stp ad160 0 0 3 0

But when I run #hwconfig -h this is what I get;

I am using Lone tar as the backup software and it doesn't recognize the tape when I do a scan.

You need to install the tape drive first using
mkdev tape

Follow the prompts to install.

I was able to fix the problem reinstalling the SCSI card driver. Thanks for your help...
