DLT-7000 and SCSI card 28696A

[Robin Rehberg]

I am having difficulty connecting a DLT-7000 to a HP SCSI 28696A card using HP-UX 10.20. After connecting the tape unit and booting the K460 an ioscan shows the device as UNCLAIMED and there are no associated device files. Can anyone shed some light on this problem?

Do you have stape,tape2 driver linked to the kernel ?
Use SAM to create device files.

Hi Robin,

For a DLT7000 to be recognized, you need the 'stape' driver in the kernel.
You may use 'sam' to add this driver and recompile the kernel.
After reboot, type 'insf -e' as this will create all necessary device files.

Best regards,

Dan

Robin,

Make sure you have the stape patch loaded on your server.
If you install the stape patch, check in the /stand/system file if the stape driver is loaded. If not add it via SAM, Kernel Parameters, drivers, rebuild the kernel and reboot the system.
Also make sure you have the famous patch PHKL_16751 installed on the server + dependencies.

Good Luck

I have all of the required kernel drivers installed and the tape unit works when connected to the HSC bus. I will try the "insf" command and see if that does the trick.

DLT7000/8000 are not supported in HPPB boards (28696A), you have to connect it in HSC/GSC. If you need to boot from DLT, you need HSC. lookup in the Enterprise servers configuration guide.

Just a thought;

If you have more than one device connected to
the PB-Bus, you will most likely require the spt scsi pass-thru driver installed in the kernel as well. I have had all kinds of problems with this in the past on G,H,I and K boxes after doing an upgrade to a new OS.
To the pundits, yes, sometimes it is alright to hang additional devices on a tape chain if they are not simultaneously used.

I have all of the required drivers and patches loaded. I have attached the DLT7000 as the only device on the 28696A SCSI card. I then ran "insf -e", still no device files. Any other suggestions?

Alright I don't know if this helps too much, but when I ordered my DLT 80E tape unit I had the same problem, well I called HP and they said that This drive will not work with the SCSI card I was using. Now I have a T box. anyways they said that I needed to order an HSC Card for T600 (part # A3644A). You might wanna give them a call and see if your tape drive needs a certain HSC card for it to recognize. After I received this card I booted up and it recognized fine.

As I remember this DLT is designed for use on workstations. To use it on servers you need to change a dip switch setting inside the DLT from 7 to 6.

If you need more detailed info let me know.
