Yes, you're right. I'm using the onboard scsi controller. Channel/scsi 0 has 5 disks (id 0-4) in RAID 5 configuration, the tape drive is connected to the channel 1, id 2.

Yes, same controller, different channel. I've included the output of dmesg for you to look at. Thanks for your help. -- > Bryan J.
