Message 0P27I says that VSE does not recognize the device at address D00, which means that either VSE's driver for OSA Express (which comes from IBM, not CSI) needs service or there's something that NICDEF does that VSE 2.6 doesn't understand.
Try using good old SPECIAL (e.g. SPECIAL D00 QDIO 3 SYSTEM DTCVSW1) instead of NICDEF. Support for OSA Express was introduced with VSE 2.6 and for hipersocket with VSE 2.7. It may be the case that you do need service for VSE. Otherwise, ADD statement in IPL proc should work without EML parameter. In DEFINE LINK in IPINIT proc, TYPE=OSAX is correct (it's not documented, but it's used for QDIO mode). Do not code PORTNAME at all. IPADDR is necessary only if you have more than one interface defined, otherwise it takes the default from SET IPADDR. Ivica Brodaric Tabcorp Sydney
