Ultrium 2/20 tar command

Hello,
I am just trying to do some checking on my new
Ultrium 2/20 tape drive. I load a tape into the drive
and type the command

tar cvf /dev/rmt/0m /tmp

I keep receiving the error

" cannot open /dev/rmt/0m "

This is the only tape drive I have on this system
any ideas???

Re: Ultrium 2/20 tar command

Hi Ross,

Two things to start with:

First, does the drive and device
appear in your
# ioscan -fnkC tape
output and
Is the tape compatible with the drive?

Hi Ross,

Can you post your ioscan -fn output for us to look at.

Re: Ultrium 2/20 tar command

Hello,

Is this the 2/20 tape library with 1 Ultrium drive or 2 Ultrium drives?

Yes, the tape drive does show up with a ioscan.

the Ultrium in it

Re: Ultrium 2/20 tar command

Hello,

From your information you have 1/20 tape library with 1 Ultrium drive in it.

In order to start a tar, an Ultrium tape cartidge must be inserted in the drive. Enter a cartidge through the mailslot and then move the cartidge to the drive. Afterwards, you can perform the tar backup.

Now, to move a tape to and from a drive, use the mc command.

Do a man mc for information on it.

Example, to move a tape cartidge from slot 2 to the drive, type:

mc -s S2 -d D1

HTH,
Vince

Re: Ultrium 2/20 tar command

Thank you for the information,
but I do have the tape in the
drive but I cannot perform the
tar command

To an earlier response,
I have one tape drive in the
library

Re: Ultrium 2/20 tar command

What does

mt -f /dev/rmt/0m status

produce?


and is the tape compatible with the drive? and is the tape writable?
