Please tell me the step by step of first time use DAT 72 external with DL380/G4

[Panuwat]

Hi all,
I have a Redhat ES3 on Proliance DL380/G4. It can detect tape device when it is booting. But it is nothing when I run command "cat /proc/scsi/scsi" and "mt -f /dev/st0 status".

Thank you.

Hi,

Are you sure that the device is detected during Linux boot or earlier during SCSI card boot (BIOS) ?

To use your DAT, you need :

step 1 : load the proper SCSI card driver (depends on your hardware, generally : aic7xxx)

step 2 : load the generic SCSI TAPE driver (st)

To automate step 1, you may need something in /etc/modules.conf, like :

pre-install st /sbin/modprobe aic7xxx (or whatever)

To complete step 2, nothing is needed. Any command trying to access the tape device will instruct the kernel to load the "st" driver automatically.

Good luck.

I also have same question, if I hope to add tape driver at DL380G3(RH8.0), how to step by step to install tape driver?

You are using a DL380 so likely you are attaching to the RAID controller in the unit, in which case it hangs off the cciss driver. You need to engage this to start the SCSI support with the following: -

echo "engage scsi" > /proc/driver/cciss/cciss0

(if there is a cciss1 cciss2 etc you may need to do these, so use a for loop). Put this command in /etc/rc.d/rc.local so it starts on boot.

After you run this, cat /proc/scsi/scsi should show your tape device.
