Have .rhosts files on all servers with "servername root" for each server.
I think you are on the right track "rmt" is "remote magnetic tape" and is normally called through "rsh" or similar. The .rhosts file should be the right approach, of course there are a number of permissions you need to check...

1. the permission to invoke rsh on the target host as the given user

2. the permission to access the tape

The first one can be tested by trying to run 'pwd', eg 'rsh -n server pwd'.

The second can be tested by login on to the box as the user the rsh will execute as and checking the rights of the magnetic tape, eg can you do

dd if=/dev/rmt/0n of=/dev/null

tcopy

tcopy(1)							   User Commands							  tcopy(1)

NAME

       tcopy - copy a magnetic tape

SYNOPSIS

       tcopy source [destination]

DESCRIPTION

       The  tcopy  utility copies the magnetic tape mounted on the tape drive specified by the source argument. The only assumption made about the
       contents of a tape is that there are two tape marks at the end.

       When only a source drive is specified, tcopy scans the tape, and displays information about the sizes of records and tape files. If a  des-
       tination  is  specified,  tcopy makes a copies the source tape onto the destination tape, with blocking preserved. As it copies, tcopy pro-
       duces the same output as it does when only scanning a tape.

       The tcopy utility requires the use of Berkeley-compatible device names. For example,

	 example% tcopy /dev/rmt/1b /dev/rmt/2b

       See attributes(5) for descriptions of the following attributes:
