configuring a quantum 7000 dlt tape autochanger w hpux 10.20

[ernest tamura]

After installing a quantum 7000 dlt tape autochanger to a 16 bit differential scsi controller on a K370 server running hp-ux 10.20 I had the following output from my ioscan -fn:

autoch 0 10/4/4.1.0 autox0 CLAIMED DEVICE ADIC FastStor DLT

target 4 10/4/4.3 target CLAIMED DEVICE
tape 0 10/4/4.3.0 tape2 CLAIMED DEVICE QUANTUM DLT7000

/devdiag/rmt/c4t3d0
/dev/rmt/0m
....

I am able to read and write to the tape using by manually mounting a tape. Is the autoch config similar to using the spt definition on an hp dss autochanger?
Are the two parts of the autochanger defined so that I can use a backup product like Omniback to control the loading and unloading of tapes? The scsi address of the drive is 3 and the robotics is 1.

Hi Ernest,

From what you mention you may still need to
create a device to use the robotics. To do
this issue a command similar to below. I have
attached a white paper for you to assist.

# mknod /dev/picker c 203 0x060000

You can use 'mc' to move tapes manually
without creating the above device, but
OmniBack which uses a program called
'uma' will need this device above.

Mike,

Thanks for the help, however the white paper did not post. Could you try it again?

Ernest,
You need to add the driver for the robotic arm, as was mentioned. If your controller that you DLT is connected to is HP-PB than the driver should be - if you connected to HSC or PCI than you would need .
You then have to rebuild your kernel. Here's some steps you can use (hope my typing is solid)
Run ioscan and get the hardware path for robotic arm

1.cd /stand/build
2./usr/lbin/sysadm/system_prep -s system
3.Check if the spt driver is already configured into the kernel:
grep spt system
4. If spt not there than add driver statement to SCSI drivers are of the system file (/stand/build/system)
spt
5. Append a driver line to the system file:
driver spt
example : driver 10/4/4.6.0 spt
6.Save the old system file:
mv /stand/system /stand/system.prev
7.Move the new system file to be current:
mv stand/build/system /stand/system
8.Build the new kernel
/usr/sbin/mk_kernel
9.Save the old kernel:
mv /stand/vmunix /stand/vmunix.prev
10.Move the new kernel to be current:
mv ./vmunix_test /stand/vmunix
11. Boot the system
/usr/sbin/shutdown -ry 0
12. After system back up confirm hardware config by running:
ioscan -fnC spt

Hope this helps,
Rita

Hi Ernest,

I've attached it again, if you don't get it
this time give me your e-mail address and I'll
send it direct.

Cheers
Michael
