testing backup tape drive

Hi,

I want to test whether the newly installed tape drive is working in a remote Tru64 5.1B server.
When I executed the dump commandline, I got the following error:

# df -k

What is happening and how to test whether the driver is working ok in this system?

Here is a list of tape drivers in the system:
# ls -l /dev/ntape/*

Re: testing backup tape drive

> dump: Cannot open file-system file usr_domain#var

It's not complaining about the tape drive.
It's complaining about the file system.

"man dump":

These commands cannot be used to archive AdvFS filesets. See vdump(8) for
the operations used to archive AdvFS filesets.


Try "vdump". "man vdump".
