Configuration of one DLT tape drive on HP-UX 11i V3

[RogerVI]

Hi,

I need historical information contained in a DLT tape.
I installed one adapter A4800A on a server rp4440. Next, I attached an external drive DLT 7000 (C6375A). The server is running an operating system hp-ux 11i v3

When I ioscan -fu shows card information:

ext_bus 22 0/4/1/0 c8xx CLAIMED INTERFACE SCSI C87x Ultra Wide Differential

But when I run ioscan-funC tape, it  does not show any line of tape installed.

What could be missing?

I've checked the loaded kernel drivers, and I loaded some of them but without success.

I have a tape library connected by SAN to the server with no problems, but I have the problem with the DLT tape drive.

Please, provide any information according your experience.

Thanks in advance.
Roger

Could I to use a conversor HVD to LVD ?

For example: RTBLVD-HVD

   Probably.

   Buy a (used) DLT7000 tape drive with a compatible SCSI interface?
That might be cheaper than an HVD-LVD adapter.
