Hi

There is nothing to fix for a user in this case.

This message is only 'informational'  - probably it could be formulated 
somehow differently and less 'stressful'

Also it's location is currently wrong, since it's the 'activation' could which 
could recognize this case - however proper fix is not so trivial and will take 
time.

So basically - this message tells you - that command operates in mode it will
process  incomplete RAID LVs - and it likely should be printed only in case 
there IS some raid LV....
