I have seen similar issues with AIX nodes in a HA cluster. We have some AIX
machines in 2 different locations and with 2 different HA configurations and
it happens only at the one location. I can get it to trigger with a demand
poll of one of the nodes.
I have also seen this behavior with duplicate IP addresses. Every time
NetView SNMP polls one of the nodes with the duplicate it causes an
interface or node down event, depending on the number of interfaces on that
node. Then when it polls the other node with that address it happens again.
It just flops back and fourth. If the cluster has interfaces with duplicated
addresses, even if they aren't on a network reachable by NetView, NetView
will discover them through the SNMP configuration poll.

I've seen the same node down on Compaq clusters when Netview does either
new node discovery or SNMP scan for configuration changes. Sorry, I
don't have a solution...

Subject: [nv-l] Monitored Server down
Hi,
Netview 6.1, AIX 4.3.2 IBM netcard TCPIP at 100 full.
HI i have a problem with Netview.
3 times a day, around 6 am, around 1:30 pm and 11 pm.
The same 4 machines, Compaq server in cluster with teaming network card,
show down. But there is nothing on the network, no backup or intense
activity. And those server aren't down. I check out the config on the
Cisco switch and there is nothing differents for thoses servers. And
they are not on the same card on the Cisco 5000. I change the snmp
configuration for thoses server polling, down status, etc, with no
results.
Someone have an idea ?
Where to start troubleshoot ?
Thanks
Ben
