Cannot find msg explaination

[Graeme Moss]

Hello Listers,

I am working on a new z/VM 5.4 rsu 0902 system. To prove the hardware I have 
set up a second TCPIP with a new OSA owned by TCPIP2. I am getting this 
message but cannot track down any information about it.

DTCOSD223E OSD device d...@0900: Return code E080 from STRTLAN for IPv4

I have done searches on DTCOSD223E, E080 and STRTLAN.

I would like to find out the meaning of the message AND how to find the 
meaning of the message

Thanks in Advance
Graeme
