ATL P1000

[Kevin Batter]

Has anyone managed to attach one of these tape libraries to a L class server running HPUX 11.0 ? We can see and use the drives ok but the robotics keep giving scsi errors though it also can be seen in ioscan ok.

Kevin,
Give us more details:
What model tape drive (product number)?
Show us what ioscan provides:
# ioscan -fnC tape
What is the SCSI error?

[Cheryl Griffin]

Kevin,
sorry for the oversight... I see it is an ALT P1000 which from all documentation I can find is an unsupported tape unit.

[Kevin Batter]

Thanks for the reply Cheryl

Here is the ioscan - the tape drives are ok as we can manualy put a tape in the drives and write data to them it is just the robotics are not working and giving an unknown scsi error (very useful !!) when we try to do anything within Legato involving the robot ie inventory,labelling

Kevin,
According to the Quantum ALT page http://www.atlp.com/pdf/swguide.pdf the unit has been certified on HP-UX.

Did you add a line to the kernel that specifically binds the arm and driver?

All I have done kernel wise is to add the driver using SAM.How do you go about binding the arm to the driver ???

[Cheryl Griffin]

Kevin,
That is probably the issue then.. bind the driver and rebuild the kernel. Then use mknod to make the special file... Here's how:

Edit /stand/system to include the line:
# driver spt
# lsdev -d sctl (to get the major number)
# mknod {device name} c {major#} {minor#}
where major# is from the lsdev
minor# is c=controller interface#
t= target#
d=lun#

Rebuild the kernel manually and reboot. If you run into any problems, then you'll need to boot from the old kernel to bring the system back up. Otherwise, test the robotic arm.

sort of tried this originaly but did mknod using spt driver not sctl as you show it.
Got told this was not the way to do this so backed it all out and just added the schgr & sctl drivers and the dev file was created during bootup ie /dev/rac/c8t0d0
Any other ideas ???

Kevin,
I found one case where the ALT P1000 was used successfully on an Nclass using exact same procedure.

Check out the Knowlege Base document for Configuring Autoloaders. This is the right procedure.

I will double check on that driver. I thought I had it correct. It should be the same driver as shows on the ioscan line for the Alt P1000.

Thanks for the assist will try this out
though still confused about the driver
