Honestly, we haven't quite figured out what happened. We're running both IP
and IPX on the cluster, and we saw a lot of dropped packets on the server.
We migrated over to the other node and have not had any dropped packets or
loss of connectivity.
I'm not convinced that our cluster is setup correctly (I didn't do it).
What I found curious is that Compaq Insight Manager emailed me an alert
stating there was a loss of communication with the volume and I had time to
open the email before I lost connectivity with the server. I know there's a
ton of cache memory in the controllers, but I realized then that our problem
was not necessarily with the switch but with NetWare. As soon as my machine
lost connectivity with the cluster my machine locked up without a Client32
message. This is what has happened to a lot of our users, though some do
get a Client32 message.
Our "A-Team" will work on this. Of course in half of the offices they put a
NetWare cluster they have had problems, and now these same people are
building crappy Exchange clusters, but they know what they're doing! Right?
NOT!
Again, thanks to all who responded. If anyone has any insight into NetWare
clusters please contact me. I'd like to be the one who can fix this...
