autoloader problem

[Juergen Nagel_1]

Hello,

I have a problem with a DLT autoloader 818. After the following commands the tape is swapped but the DLT device is offline.

export LIBRARY=/dev/rac/c4t6d0
mt -t /dev/rmt/0m rew
sleep 60
/usr/sbin/mc -sD1
sleep 300
/usr/sbin/mc -sS$T -dD1
sleep 300

Who has an idea?
Thanks

Hi there.
Sorry, but did you check the manpages of the mc command ?
May help just a bit.

Yes, I did it.
Nevertheless I found not the right answer.

Hi,

To move tapes around an Autoloader properly
you need to create a robot device. Have a
look at the attached document. Once configured,
you can move tapes around doing this:

Assume that you device is /dev/robot:

# mt -t /dev/rmt/0m rew (rewind tape)
# mt -t /dev/rmt/0m offl (take drive offline)
# mc -p /dev/robot -sD1 -dS1 (move from source
to destination)
# mc -p /dev/robot -sS2 -dD1
