+1 to a real python API. We have written our own, albeit incomplete, library to expose most of what we need. We would be happy to share some general ideas on what should be included, but a real IBM implementation wouldn't have to do what we did. (Think lots of subprocess.Popen + subprocess.communicate and shredding the output of mm commands. And yes, we wrote a parser which could shred the output of either -Y or tabular format.)

I'm pretty certain Yuri told me that mmlspool was completely unsupported and didn't have -Y a couple of years ago when we did the original GPFS UG RFEs prior to 4.x. I figure that earns cookies. Perhaps in light of the mmbackup thread; "Will fix RFEs for cookies?".

That's right kids... no more parsing obscure, often changed output columns with your favorite bash/awk/python/magic.
