Not sure if you've got an answer on this yet ... but better late than 
never ... as I just had to figure this out today.

This answer applies if you executing your dump command as root.

dumping to a remote tape drive involves using rmt.  rmt is executed via 
rsh on the remote.  By default many systems don't allow root access via 
rsh out of the box.  On Red Hat Linux you can enable it by adding the 
line "rsh" (without the quotes) to /etc/securetty.  This file contains 
the "devices" that root is allowed to logon.

Note enabling root access via rsh could open a security hole on your 
machine unless its well protected.  So understand the ramifications of 
this change before applying it.
