OSA-2 sharing between Linux LPARS

[Doug Clark]

I need to share between two LPARS - (that have working copies of Linux
running on each LPAR with separate IP addresses and Hostnames) - a single
OSA-2 adapter.  The first LPAR that I activate "owns" the OSA-2 adapter and
the second LPAR does not have network access.  Can someone please point me
to a manual or documentation that can walk me through this configuration
effort?  If this is even possible.  Sorry no VM/z and OSA-E is not currently
available to me.
