We have a kicking VA Linux 4450 server with a VXA-V17 tape drive in it. Unfortunatly the tape drive isn't seen by linux. It shows up in the scsi bios utilities. There is no mention of a tape drive in dmesg or /var/log/messages after bootup, and it doesn't work when you try something like "mt -f /dev/st0 status". The drive is on scsi channel B, does that make a difference? Is there some way to scan the scsi bus manually? I checked /proc/config.gz and tape drive support is built in. Any ideas, suggestions? -Marc

What happens if you cat /proc/scsi/scsi? I get something like the following:
cat /proc/scsi/scsi Attached devices: Host: scsi0 Channel: 00 Id: 00 Lun: 00 Vendor: SEAGATE Model: ST15150W Rev: 0023 Type: Direct-Access ANSI SCSI revision: 02 Host: scsi0 Channel: 00 Id: 02 Lun: 00 Vendor: HP Model: C1533A Rev: 9503 Type: Sequential-Access ANSI SCSI revision: 02
This at least lets you know if the system sees the thing. The next question is: does your kernel have SCSI tape support? Cat /proc/devices, do you see something like:
cat devices Character devices: 1 mem 2 pty 3 ttyp 4 ttyS 5 cua 7 vcs 9 st [...]
Is /dev/st0 correct (ie: major 9, minor 0)?:
ls -la /dev/st0 crw-rw---- 1 root disk 9, 0 Oct 23 1999 /dev/st0
