Thanks again for your time. I have an internal Western Digital 4 GB HDD at target 0. At target 1 is a Quantum DLT4000. The DLT4000 is inside the autoloader. At target 2 I have a CMD TECH CRD-5440 RAID. At target 3 is the changer. The Adaptec host adapter is target 7. The changer and the DLT4000 are separate SCSI devices. The changer does not communicate with the tape drive on the SCSI bus. Both the changer and the DLT4000 are SCSI-2 devices. The changer handles medium transport and storage. The drive handles data transfer. So, on the back of the library, the host connects to the DLT4000. there is a SCSI bridge that connects the DLT4000 to the changer, then the changer is terminated. Here's what dmesg has to say about the SCSI bus: ahc0 <Adaptec 2940 Ultra SCSI host adapter>rev 0 int a irq 15 on pci0:15:0 ahc0: aic7880 Wide Channel, SCSI Id=7, 16 SCBs ahc0 waiting for scsi devices to settle (ahc0:0:0): "WDIGTL WDE 4360-1807A3 1.80" type 0 fixed SCSI 2 sd0(ahc0:0:0): Direct-Acess 4095MB (8388314 512 byte sectors) (ahc0:1:0): "Quantum DLT4000 D069" type 1 removable SCSI 2 st0(ahc0:1:0): Sequential-Acess density code 0x1a, drive empty (ahc0:2:)): Direct-Access 121564MB (248964352 512 byte sectors) (ahc0:3:0): "QUALSTAR TLS-4210 128b" type 8 removable SCSI 2 uk0(ahc0:3:0): Unknown I just wish that Unknown would become something like Medium-Changer and uk0(ahc0:3:0) would become ch0(ahc0:3:0). Is there anything I can do to make this happen? On Thu, 16 Jul 1998, Doug White wrote: > On Tue, 14 Jul 1998, Eric Patterson wrote: > > > I have now read st(4), ch(4), and chio(1).
