tar to remote tape

I tried to buckup some oracle archive logs (from a solaris machine) to a remote tape (in a HP-UX machine).
I added the solaris machine name and user to .rhosts, and i tried to use this commande :

tar cvf HPhost:/dev/rmt/0mn /u01/*

The probleme that it gives:

HPhost:/dev/rmt/0mn : No such file or directory

Is there any solution for this ??

Thank you for help

Before attempting to tar any files you need to insure you can get into the server - doing a rsh systemname uptime or other type command will assist with that.

See this post and the link in it for a instruction on how to do it.
