Someone can help me???....
I've a Tandberg Tape SLR5 mounted on e-smith 5.6.
It's a SCSI devive on Adaptec Controller type 2904.
How can I see if this device is started on this OS?? and(or can I try with some command this device???

thanks

You could try the following command as root:

mt -f /dev/st0 status

If it returns some information (other than an error), that will tell you that the drive has been detected OK. Otherwise check the messages when your machine boots, something should show up there as well.

Hi Neal Collins,
I've tried the command mt -f /dev/st0 status.
Ittell me: /dev/st0 No Such device.

At startup:
...................
SCSI subsystem driver Revision: 1.00
kmod: failed to exec /sbin/modprobe -s -k scsi_hostadapter, errno = 2
PCI: Setting latency timer of device 00:09.0 to 64
ahc_pci:0:9:0: Host Adapter Bios disabled.  Using default SCSI device parameters
scsi0 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 6.2.6
       
        aic7850: Single Channel A, SCSI Id=7, 3/253 SCB

Do you want help me???

Thank you

This command should work

mt -f /dev/nst0 status

[Raffaele Capasso]

The system tells me:
/dev/nst0 No Such device.

I've need help. I don't know how to do.

Thanks

Hi Raffaele,

Let's check the basics.

When you type :-

cat /proc/scsi/scsi

What does it say ?

When you type :-

lsmod

Can you see the aic7xxx, st and scsi_mod modules listed ?

Hi Kelvin,
very very thanks.

This tells me your tape drive is not being recognised.

Your lsmod listing seems to show that all the relevant modules are loaded for the SCSI card. I would suggest you check :-

a) The power and SCSI cable going to the tape drive
b) The SCSI ID of the drive
c) Termination of the SCSI Bus

Kelvin

[Raffaele Capasso]

Hi kelvin,

a) The power and SCSI cable going to the tape drive: It's OK

b) The SCSI ID of the drive : now I control and then I tell you

c) Termination of the SCSI Bus : The instructions of Tandgerg said that the cable must be terminated with 10 cm of cable. Then I've attached the drive on the penultimate attach but I don't terminate the cable with the appropriate terminator.

When the system starting and the SCSI adapter is loaded I feel that the tape in the drive moves.

Thanks

[Kelvin]

Hi Raffaele,

I'd check the termination. Some controller / drive combinations are more tolerant than others. If you can get the termination right, it will at least remove that as a possible reason for your problem.

Keep the terminator at the *end* of the SCSI cable and be sure to use the right terminator for the cable / bus. I've not worked with a SLR before so I don't know if they have onboard termination or not. If they do, activate it if your SLR drive is the only device on the SCSI cable and remove the terminator your might have installed on the cable. If the SLR does not have on board termination, then attach the terminator to the end of the SCSI cable and your drive between the controller and the terminator (again I am assuming the SLR is the only device on the cable). You might also try setting the SCSI controller's BIOS settings to default and see if it helps.

Do you know any utility DOS for Adaptec 2904 for test the situation?

Thanks

[Kelvin]

You could try using the Tandberg Drive Optimiser from their website to see if that detects the drive properly or not. You will also need the DOS ASPI drivers from Adaptec as well.

[Raffaele Capasso]

Hi,
I've added a terminator at the last of the cable, I've changed the id from 1 to 4 and other, but the tandberg slr5 is invisible.
In italy it is said: "What's balls!!!!"
which things must I, stil,l try??

Thanks
