I am looking to migrate my Mdata from mirrored 3TB drives to mirrored 240GB SSD drives. I know that the standard utility will create something that might become unuseable, but I am sure there must be a way to do this. Has anyone successfully done this action?
XSAN 3.0-OTHER, OS X Mountain Lion (10.8.5)
Take a look at sndiskmove. (man sndiskmove).
Have a good backup. Follow all precautions.
I don't know if sndiskmove will work going from a larger to a smaller LUN as the OP wants. There's an old Xsanity post talking about this here:

That article notes that it didn't work in Xsan 2(.0?). I don't know if it's still true in Xsan 3.
