Ufsdump to remote AIX tape drive

Question

I am trying to ufsdump to a remote tape drive that is on an AIX box.
I have configured the /.rhosts file on the AIX server
I have created a symbolic link /etc/rmt to point to /usr/sbin/rmt on the AIX box
I am running the following command on the sun box
ufsdump 0cuf AIXBOX:/dev/rmt0.1 /dev/dsk/c1t0d0s0
but I get this :
DUMP: Date of this level 0 dump: Thu Feb 18 15:42:17 2010
DUMP: Date of last level 0 dump: the epoch
DUMP: Dumping /dev/rdsk/c1t0d0s0 (SUN10:/) to AIXBOX:/dev/rmt0.1
DUMP: Mapping (Pass I) [regular files]
DUMP: Mapping (Pass II) [directories]
DUMP: Writing 63 Kilobyte records
DUMP: Estimated 12017946 blocks (5868.14MB).
DUMP: Lost connection to remote host.
DUMP: Bad return code from dump: 1
DUMP: Date of this level 0 dump: Thu Feb 18 15:42:28 2010
DUMP: Date of last level 0 dump: the epoch
Is it possible to get this to work?

Answer 1

If i interpreted the code to ufsdump correctly, it will attempt to execute the command /etc/rmt on the remote host over a shell (port 514) connection.
The rmt supports the remote magtape protocol, so ufsdump creates a datastream and sends it over the network to rmt, which is responsible for sending it to a tape device.
Is there an /etc/rmt binary in AIX? In Solaris there is a /etc/rmt, even if its just a link to /usr/sbin/rmt, if there isn't a /etc/rmt, check if there is an rmt binary elsewhere on the system, and symlink it.
If there is a /etc/rmt, two other things to check would be that the shell connection is working (by running something like 'rsh AIXBOX echo hej') and double check the path to the tape driver on the AIX host.
Hope this helps, i am not that experienced in remote taping nor AIX.
