Question tape installation


Hello there.

I've installed fedora core 1 and everything works fine.

Today I've added an adaptec AH2904 SCSI card with an attached external DEC TZ87 DLT tape drive.
During the reboot the operating system told me that a new scsi controller was detected and the drivers loaded.

The scsi card and the tape drive seems to be installed correctly, but the tape drive doesn't work.
When I try mt -f /dev/st0 status I get
"No such device or address".

So I checked the following things:

- in lsmod output I can see the lines for st and scsi_mod
- the file /proc/scsi/scsi is empty
- in dmesg output I can see:

ahc_pci:0:12:0: Host Adapter Bios disabled. Using default SCSI device parameters
scsi0 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 6.2.36
<Adaptec 2902/04/10/15/20C/30C SCSI adapter>

Attached scsi tape st0 at scsi0, channel 0, id 5, lun 0
st0: Block limits 1 - 16777215 bytes.
scsi : 0 hosts left.


Please help
S.

Have you tried writing to/reading from it even though status doesn't work?

# cd /tmp
# tar -cvf /dev/st0 *

Or something like that...

Yes, I've tried with tar to write to the tape, but I get the same error "No such device or address".

Thanks

Thanx siddiqu.
Here is my lsmod output:

The module "st" seems loaded, but the tape doesn't work.

Any ideas?

Hi..


Fine. but ur adaptec module is missing in this list.

try modprobe aic7xxx

Also check ur modules.conf entries also.

This is my modules.conf:

alias eth0 3c59x
alias usb-controller usb-uhci
alias scsi_hostadapter aic7xxx


I've tried the command modprobe aic7xxx. After that the tape works fine.
However if I reboot the machine the tape doesn't work again.

How can I make the tape working across reboots?

Thanks again
S.

PMFJI (pardon me for jumping in), but I found an answer to this elsewhere, so I thought I would forward it to you:
