Problems configuring DVD-ROM and DDS Tape devices to A500 running HP-UX 11.0

[Anthony Chau]

I'm an inexperienced system administrator and have read the HP 9000 Configuring HP-UX for Peripherals manual. I'm having problems configuring an HP C6365A DDS tape rack-ready drive and an HP C4315A Rack-ready DVD-ROM drive to an A500 server running HP-UX 11.0. The DVD-ROM and DDS tape devices are in an HP C4328B Smart full height enclosure. The DVD-ROM has a SCSI ID of 1 and the DDS tape has a SCSI ID of 3. The DDS tape is terminated and daisy chain connected to the DVD-ROM via NSE SCSI connectors at the back of the full height enclosure. The DVD-ROM is connected to the NSE SCSI card (hardware path 0/0/2/0) on the A500 server. Using SAM I have added or confirmed that the scsi1, scsi2, tape2, and disk3 drivers have been added to the kernel. I have rebuilt the kernel, rebooted the server, all devices are powered on. However, in the ioscan, the DDS tape and DVD-ROM devices are not found. Only the bus and controller for 0/0/2/0 are found. Any suggestions on what else I need to do to complete configuration or diagnose my problem?

Hi
The first thing to do is connect each device seperatly and see if they can be seen.

Just a starting point.

Anthony,

As Paula suggested, first connect the tape device to the server.
The bus where the tape-device is connected, is that a HSC or GSC, if yes, then you need the stape driver.

- Halt the server (shutdown -h 0), power down.
- Connect the tape-drive
- boot the server.
- If the tape device is not seen with ioscan, run insf -e.
If this doesn't work try to create the tape device manually, with mksf -H ???(see man mksf)

If this works then start with the DVD.

Better than ioscan -fn or any other HP-UX command, halt that boot process and go to ODE and use MAPPER. This is a very low level, can-I-see-the-electrical-connection, diagnostic utility. If it is not loaded you will find it on your support disk. I recommend it highly. If you need a step-by-step I think the cumulative wisdom of this forum can supply it. BTW, try only one device at a time, it will be easier to isolate and fix the problem.
