I used this command from the Nearstore
ndmpcopy -sa root:passwd -da root:passwd 840:/vol/vol0/test
NearStore:/vol/vol0/
(I used the real names for the 840 and the Nearstore)
This is what I got:
Ndmpcopy: starting copy [13]
Ndmpcopy: Trouble connecting to destination NearStore
Ndmpcopy: fatal error. Aborting....
Ndmpcopy: Done
