I am new (about two weeks) to the HP/UX environment and have only recently
started to read this group so I apologize if this is a FAQ. Also, please
forgive me if I sound ignorant. It happens alot!

I am working on a HP9000/300 that has a 9144 cartridge tape unit. We want to
backup the disk to the ct. I started a dump but at 1% every 6 minutes I soon
realized that the procedure would take about 10 hours which is a lot of down-
time. So, I stopped. I then attempted to rewind the tape using
"mt -t /dev/rct/0s0 rew".  This returns rewind 1 failed: invalid argument.
I get similar results for different commands and messing with the arguments
gives other, more obvious errors such as the device is not a typewriter (go
figure). I got around this, I removed the tape. Then I tried using the tcio
command (after trying backup first) in conjunction with ls and cpio, much like
the man pages show. This allowed me to write the directories and files to the
tape (or appeared to) but won't let me read them. I get a variety of messages
depending on whatever. I have used tcio -u stuff too and that sometimes "seems
to work". tar works fine as far as I can tell. I was able to write and read
files; that means it's working to me. I am getting pretty annoyed.

Does anyone have any clues or suggestions about what is going on? Any help at
all will be much appreciated. E-mail preferred. Thanks.
