From the top of my head (I can't verify anymore, no access to z900 lpars

But what won't work on a z900, is sharing the osa with layer 2 and layer 3

Correct - the OSA adapters available on the z900 do not support layer
2. You need an OSA Express 2 and at least a z990 or z890 at the
correct code level.

Hi, Russ.
The EDCPLINK appears to be doing some sort of link or bind processing of

you might try increasing the virtual storage size of MAINT to, say,
