What error message did you get?  Did it say it could not find any gridded data 
or some other message?

That's not a udunits compatible specification which is what CF requires.  Using 
the month abbreviation does not conform to the ISO8601 standard.  You should 
use:

MYTAXIS2:units = "DAYS since 1901-01-15"

What Convention does it say it uses?
