Kent, Thanks for responding. Here's a screen print of my kernal configuration: # SCSI peripherals # Only one of each of these is needed, they are dynamically allocated. controller scbus0 # SCSI bus (required) #device da0 # Direct Access (disks) device sa0 # Sequential Access (tape etc) #device cd0 # CD device pass0 # Passthrough device (direct SCSI) The only thing I see that is missing is device ch #SCSI media changers I don't think adding this line would change anything, since my tape drive isn't a media changer. It's just a single drive that holds only one tape at a time. If you need to see a larger view of my kernel configuration, please let me know. Thanks again, Joe |--------+-----------------------> | | Kent Stewart | | | <kstewart@urx| | | .com> | | | | | | 08/10/00 | | | 10:57 AM | | | Please | | | respond to | | | kstewart | | | | |--------+-----------------------> >---------------------------------------------------------| | | | To: Joe Warner/SMS@SMS | | cc: freebsd-questions@FreeBSD.ORG | | Subject: Re: Device not configured?

Do you have # SCSI peripherals device scbus # SCSI bus (required) device ch #SCSI media changers device da # Direct Access (disks) device sa # Sequential Access (tape etc) in your kernel. You need the "sa" to access your tape. If it was an autochanger, you would need "ch". My tape drive is temporarily not hooked up to the server so I can't show you the dmesg output.
