Hi managers,

I've got a problem with our suncluster 3.0 ...

The cluster's running on two Fire-480-nodes. On both nodes I defined a
nafo group "nafo0" with only one adaptor "ce0" (due to time and gardware
lack).

Now I get the following in /var/adm/messages on _both_ nodes:

This 'nafo-pingpong' does not occur on our E420-cluster (two nodes, too)
with hme-devices. Due to the fact that I saw a Fire-480 first time last
week I'm not sure what causes this. (The node itself is reachable over
that interface permanently, only the clustersoftware does not think so
:-( and because of that several resource groups often switch primaries.)

Should anybody have an idea what _should be_ wrong, I could send a
tracefile of pnmd...

Of course I'll summarize.

Thanx a lot for your help,

Marcel
