Ultrium 2 - multi-tape error (DUMP: fopen on /dev/tty fails: No such device or addres
 

I have successfully backed up a 300-GB RHEL4u4 Linux partition to a remote Ultrium 2 tape drive on a Solaris 9 box many times. All of a sudden, when the dump hits the EOT, instead of waiting patiently for me to change tapes, the dump aborts:


DUMP: Change Volumes: Mount volume #2
DUMP: fopen on /dev/tty fails: No such device or address
DUMP: The ENTIRE dump is aborted.

I used a cleaning tape, tried 3 other new tapes, power cycled the tape drive and rebooted the Sun computer. I also tried the dump from a Solaris 9 machine to the Ultrium and it also fails in trhe same way.

Any suggestions would be greatly appreciated.

Hi

Same Error Appearing in Server.
what is solution?
why happen this?

It looks like you're running the dump via a remote terminal rather than via the host system's console? My guess (and it is just a guess!) is that dump needs to have you interact with it (Type "yes" or "no" or something on the system console, not a terminal)
I can't cut and past the relevant section from between my laptop and RedHat VM I'm afraid, so you'll have to check out the manual page yourself. End-of-tape is one of the conditions intervention is required apparently.

Can you run your multi tape dump from a local console or via a terminal server connected to the console?
