Errors after going to z14 with OSA-Express6S

If you have migrated to a z14 and are using an OSA-Express6S card on this processor, you need to have TCP/IP APAR PI73016 (included on RSU 1702) applied.

APAR PI73016 updates the NETSTAT OSAINFO command output for the OSA-Express6S cards, and also corrects a TCP/IP connectivity problem that can occur when TCP/IP is using an OSA-Express6S device in Layer 3 (IP) mode. The issue occurs due to a header mismatch error between the QDIO header and IP header (these header lengths will no longer always be the same as of OSA-Express6S).

Customers who encounter this issue will see error messages similar to the following in the TCPIP server console log:

  QDIO device DEV24 device number 3400:
    encountered a transmission error
  Input queue 80000000 location: 04 error code: 00 index 00

Again, this problem is corrected by APAR PI73016 (PTF UI49565 for Release 6.4.0), which is on RSU 1702 (or later).
