Tape device under Soaris 2.6

[microsky]

Any one can help me ? I have 2 questions about tape device in Solaris .
1. How can I share the tape device to other hosts under solaris2.6 ?
2. I have a tape DLT7000 35/70GB,how can I use it as 70GB . I had try to use this device as /dev/rmt/1hn,/dev/rmt/1un and /dev/rmt/1ln ,but the maxsize of these types is also 35GB , regardsless of I use which format of them ,on the control panel,the light of '35GB' and 'Compress' is working .
Thanks!

For larger groups of Boxes Legato's Networker works great, but If you just want to back up one or two boxes, consider reversing your plans, remotely mount the drives on the tape box and back them up there, it is much simpler than remotely using the tape The one thing you can't give for your heart's desire is your heart. - Lois McMaster Bujold

I may be off base here, but have you tried using the compressed version of the device, for example /dev/rmt/1cbn?
Hope this helps.

Alernatively to the reply from jimbopalmer , you can also do a rsh from the host that has the drive to the host you want to backup and do a ufsdump (or other like tar or cpio) if you do not wish to share the drive.

we get 70ish Gig per tape with /dev/rmt/1hbn but /dev/rmt/1ubn may be theoretically higher, Legato wants them to be berkeley devices The one thing you can't give for your heart's desire is your heart. - Lois McMaster Bujold

As Ken said, the c in /dev/rmt/1cbn is for compression.
h = high density
u = ultra high
You need the compression for 70Gb capacity.

I added A DLT 8000 to my solaris 7 server;
I had to add the device to a configuration file
somewhere; you input the device name, and some numbers
and then after reboot it will be able to talk to it.
here is a page that has the procedure:
