What is causing TCP/IP error message EZZ4310I CODE 8010302C when starting OSA QDIO device?

Question & Answer

Question

The following error appears when starting TCP/IP QDIO (OSA) device:

EZZ0060I PROCESSING COMMAND: VARY TCPIP,,START,device_name
EZZ0053I COMMAND VARY START COMPLETED SUCCESSFULLY
EZZ4310I ERROR: CODE=8010302C REPORTED ON DEVICE device_name. DIAGNOSTIC CODE: xx

Answer

This error occurs when there is a mismatch in VTAM and TCP/IP definitions. The device_name specified in the TCP/IP DEVICE and LINK statements, or the portname specified on the PORTNAME parameter of the TCP/IP INTERFACE statement, must match the PORTNAME specified in the VTAM TRLE statement for the OSA-Express QDIO PORT.

Also, all LPARs using the OSA PORT on a CEC must use the same PORTNAME. The OSA will remember the first PORTNAME that is used to activate the OSA PORT. All subsequent users must use this same PORTNAME. If an incorrect name is used and is remembered by the OSA, the OSA can be reset using the VARY OFFLINE command for all CHPIDs that used that OSA PORT.

To resolve this problem, use the same PORTNAME (device_name in TCP/IP DEVICE and LINK statements, or portname in TCP/IP INTERFACE statement) in all VTAM and TCP/IP definitions that use an OSA PORT.
