Create a ram disk
 

Hi,
I have been told that the driver for Ultrium 460 tape under AS 3 exists since AS 2.1 and that I need to modify the scsi config and create a new ram disk which will recognize the device at boot.
1- Is this true ?
2- How to modify the scsi config and how to create a new ram disk ?
Regards
Consty

No, at least not that I am aware of. AFAIK the SCSI tape module st in addition to the SCSI controller and the scsi_mod should work. Check the output of the command lsmod to see if the modules are loading. The SCSI tape device will be /dev/st0 & /dev/nst0 for rewind and no rewind after tape operation respectively.

Create ram drive (followed)
 

Hi,
There is no /dev/st0 nor /dev/nst0 device.
There is something to do to create the device, I don't know what.
THanks

Post the output of the commands
lspci
lsmod

This will tell us what SCSI controller is installed in your PC and what modules are being loaded.

Your SCSI controller module is not loaded. Try:
modprobe sym53c8xx

Hi,
No change after modprobe command.
Looks like the BIOS see the driver (Ultrium) but Linux does'nt see any driver
for HP Storage Ultrium 460 or I don't see a name related to that.
Regards

What do you mean by no change? Was there an error message like 'module not found' after you entered the command?

The SCSI tape module is called st and it is being loaded according to the output of lsmod. AFAIK this is the only tape drive required.

Look at the output of the dmesg command. Are there any messages relating to the SCSI controller module?

I solved the problem by re-installing Linux, I think that the system detected
the adapter and loaded the good driver and options.
Thanks a lot for your help
