Re: Can not see DDS4 tape drive on HP-UX 11.31 system
I think either your tape drive is dead, the cable is bad or the scsi connection is not properly terminated.

Check the SCSIDiffsnse & Term PWR LEDs on the Core I/O and note their condition when the drive is being detected along with the DVD connected.
Then compare the LEDs when the DVD is connected by itself and then again with the DDS4 alone to isolate whether you have a termination, cable or other configuration issue.

Re: Can not see DDS4 tape drive on HP-UX 11.31 system
the c2362a cable will be fine, its an lvd cable only 90ohm but should be sufficient for the tape device.
the c2364a terminator is correct too, but i have seen these fail over the years. strange and knowing abit about how they work seems difficult to work out why, but they do.
I would also check the pins in the terminator. if just one is bent and not connecting you will likely get the result you are seeing
dont suppose there is anything in the syslog.log about the scsi interface on boot up?

These are true for two different cables and two different terminators.
I thank all of you very much for your help. I'll be experimenting with your suggestions when I retun on Monday. Thanks, and have a good weekend. lko
