Tape Drive cannot be found


Please help.

I am new in RHEL5 . We have an iBM LTO4 tape drive
and we cannot run our backup because the /dev/st0 is not
there.

I tried the following but negative result.

http://www.linuxquestions.org/questi...-drive-833108/


Please help.

========

By the way. iBM guy came and replaced the SAS card controller. Now the Tape drive is detected in the BIOS.
but on the OS side its no.


Thanks.

Don't you have to modprobe a module (e. g. load a device driver) to get that drive to work?

For example, to make my 3G modem work I need to

Code:
modprobe usbserial vendor=0x12d1 product=0x1506
modprobe option
which then creates the /dev nodes I need where applications (specifically KPPP) can access and use the device.

However, since you had an apparent hardware failure, it is also possible that something is still broken?

Did it work beforehand?

Hi Rylan,

Thank you for taking time helping me.
The device is working fine since iBM tested writing
within the device but not loading Linux.

Inside the linux I cannot /dev/st0 at all. Would you
be kind enough to guide me how to probe the device?
I am using an LTO4 by the way and I am not sure if that helps.

Can you please post the output of the console command

Code:
lspci
and

Code:
lsusb
?

This will give you an idea if the kernel is seeing your device at all.

How does it connect to the mainboard? Via USB or a slot-in card in a PCI (white coloured) slot?

You'll need to look for a driver for it, maybe you can contact IBM / the vendor and inquire about a Linux driver for it?

Please use the -k option for lspci! I want to see which modules are loaded for the device.

Well, I forgot to ask, how is the tapedrive connected to the computer. I supposed it's at the serial port.

Since RHEL as the name says (RedHat Enterprise Linux) is a supported distribution, you should ask Redhat for help. Thy should be familiar with problems that occur with typical serverhardware.
