We tried this on our 256-node cluster with a single chassis Voltaire
288-port switch.  It seems to load the routes generated by the dump
script, but afterward it is not possible to dump the routes again.  I
would like to re-dump the routes after loading to ensure that they were
loaded correctly.

After loading routes with "opensm -R file -U dump_file", dump_lfts.sh
gives:

nodeinfo
0000 0000 0000 0000 0000 0000 0000 0000
0000 0000 0000 0000 0000 0000 0000 0000
0000 0000 0000 0000 0000 0000 0000 0000
0000 0000 0000 0000 0000 0000 0000 0000
ibroute: iberror: dump tables failed: node info failed: valid addr?

for each switch.

Also, I had to delete a space in the sed script on line 17 of
dump_lfts.sh:

sed -ne 's/^.* lid \([1-9a-f]*\) .*$/\1/p'

became

sed -ne 's/^.* lid \([1-9a-f]*\).*$/\1/p'

Thanks for the work!
