Ronald, Thanks for your information! I checked our z900's configuration. It should be OSA Express in stead of Express2.
There is one thing I couldn't understand. The z/OS on another LPAR can work well on ipv6. They used the same OSA adapter.

But what won't work on a z900, is sharing the osa with layer 2 and layer 3 traffic. As I recall, the first to connect to the OSA could set the mode (2 or 3) and all other shared connections have to use the same mode (just like the portname). The restriction got lifted with z990, there you can use the same shared OSA, mixing layer 2 and layer 3 connections.
