Is the error message that you are seeing, similar to?
volume is not online; cannot execute operation
If so, the above error occurs if a snapmirror schedule attempts to run for a volume that has not completed initialization.
On the fas3140, what is the setting for
'options snapmirror.access'
On the fas2040, are you issuing a snapmirror initialize command similar to:
'snapmirror initialize -S fas3140:source_volume fas2040:vol1'
If so, what is the error that you see on the fas3140 and fas2040 console?
