fbackup on remote DDS problem.

[Mubarak Rebhan]

I was trying to use SAM for backing up files on a DDS tape at a remote host.
The fbackup utility ended with the message:
Could not open device file host:/dev/rmt/0m

Any idea what could cause such a problem?

Hi,

from the host, where you want to start the backup, ensure that remote-shell works ok for the user that takes the backup:

remsh host_with_tape bdf

Should list the filesystems of the other host.
This must work, otherwise your backup will not work ! You might need to set up .rhost for this!

Check if you can eject the tape remotely:

remsh host_with_tape mt -t /dev/rmt/0m offl

If this works, your backup should work!

Hope this helps

Thank you for the reply, but ti did not work until now.
The remote host is defined in the .rhosts and /etc/hosts.equiv and yet could not access the DDS tape.
remsh commands did not work (login failure) and when I tried rlogin, it asked for a password.
Any idea how can I rlogin or remsh successfully?

Volker,
It is working now.
Thanks alot.
my .rhosts and /etc/hosts.equiv were OK but the /etc/hosts does not have the reomet host name.
rloing, remsh and fbackup is working now.

Regards.
