You need one system with DIRMAINt and the two others with DIRMSAT. Note a pitfall that I remember from the 9221 days when I impleted it: one of the DIRMAINT's minidisks should never be linked by anyone, or the DIRMSAT workers won't run.
Nifty. Glad to know that this is now supported for more than CSE. Learn something new every day... 8-)
