Help with tar, Anyone know the correct command to make a segmented tar file?

[Cleo]

I'm moving a bit over 10 gigs from server to server.

Problem is when I go to tar the directory it seems to get stuck at 2 gigs.

Seems like there should be a way to have it make segment.

I tried
tar -L2000000 -cf archive.tar directoryname

But this seems to want me to insert the next tape after it finishes the first segment.

Anyone know the correct command to make a segmented tar file?
