I am also trying to find any documentation that describes this issue. The
lpar that we are setting up will eventually be shared with a 2nd lpar with
a similar configuration. If I cannot share the OSA I may have a problem.
Can someone, maybe IBM, describe in more detail what can or cannot be done
with VSWITCH's ?
Alan had also mentioned "As long as you don't connect a routing guest to
two VSWITCHes at the same
time, you shouldn't have any spanning tree problems."
Does this include firewall routers or guest lan (or another internal
vswitch) between these servers ? Is there any information about this I can
read about this, is this something a LAN administrator would know ?
Thanks,

Would you please eloborate on this? I have multiple VLAN-aware VSWITCHes
sharing the same OSA with no problems. Each VSWITCH has a distinct and
separate set of VLANs, if that makes any difference. This setup is
required to connect non-VLAN-aware guests to multiple VLANs via VSWITCH
GRANTs.
If there is a pitfall in there somewhere I'd like to know more about it.
