HP SAS ULTRIUM448 DRV on DL380 and Redhat 5.1ES

[jayantha]

Hello,
My DL380 on Redhat Linux ES5.1 contains an external tape connected to E500 array controller. One of the external port in E500 has a external starage. Other got this tape drive.
From Insight manager Home page I can see the drive as "HP ULTRIUM448 DRV - Bus 1 Drive 0". But from OS if I issue "#mt -status" it doesn't identify any tape drive. What could be the device default path in OS for SAS tape drive.
Please Help me,
/Thanks.

Shalom,

You need to install drivers from HP to this OS to support that drive. I never liked 5.1, 5.2 was more stable and might have a built in driver.

I have installed softpack hp_ltt47. Still its same. How can I check wethere it is installed corectly.
Is there any way to see the Tape drive path.

You should "engage" the external SCSI port.

Try with:

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

If it solves your issue, add the following lines to /etc/rc.local (RHEL, your case) or /etc/init.d/boot.local (SLES, for reference)

----
for x in /proc/driver/cciss/cciss[0-9]*
do
echo "engage scsi" > $x
done

Thank you very much for your attention on this case, RHEL option worked well....So I'm using it now.
