The QDIO and QETH OCO issues were resolved. The only OCO bit left is the 3590 support, even the crypto stuff is open source.
-----Original Message----- However, I suspect the OCO problem is what's holding things up. The dasd susbsystem business is cutthroat and keeping any advantage is of paramount importance. Its the same as the QDIO OCO issue (except that everyone else is getting out of the mainframe business).
