Automatic DAT tape eject

Edward McCouch — Mon, 07 Jul 2003 13:57:12 GMT

I wrote a script that checks for the existence of a DAT tape, checks the write protection and then eventually starts a make_tape_recovery script. Now I would like to add a line that ejects the tape.

The mt command doesn't seem to have an eject command and I am not sure what other commands I should be looking at. Any help would be appreciated.

OS= Hp-UX 11.11
Server= rp5470s
DAT tape= DDS4s & DDS3s

Thanx in advance.

Try "mt offl"

Hi:

Use this:

# mt -t /dev/rmt/0m offl

Hi,

I've done it before with the 'mt' command. Try this:

mt -f /dev/rmt/0m offl

and see if it doesn't eject your DDS tape.

offl option in mt command should do this.

Hi,

If the tape is /dev/rmt/0m

I use :-

mt -f /dev/rmt/0m offline

Regards,

sounds like a very useful script. I'm sure a few of us would love to have a copy. So, if you can it would be nice if you could post a copy.

isn't there a favorite sys admin scripts thread, if you post it there you can even get points for it.

Thank you all for responding so fast. I feel a bit foolish--I looked at the man page and saw the offl, but for some reason I thought that would make the tape drive go offline. I think I need to drink some more coffee.

I'd post the script, but it is very crude and barbaric, although if you want a good laugh, I'll seek out that thread and post it in there. I'm a beginner so the script is just a bunch of cobbled together commands and lacks the elegance of most of the scripts that I've seen.

Thanx again!

I've just tested this command and it works equally well on Ultrium Tape Drives.
