Hi,
We do have have problems with an 3-node HACMP cluster ver. 5.3
So the scenario is that we have 3 nodes and a concurent RG and all the
3 nodes are participating in it.
Each node has private and public interface (the minimum scenario, no IP
address or alias take over defined yet), the network connectivity is
just fine, the configuration is double and tripple checked by 3 CEs and
big number of references.
The verification and synchronization is completing with 'Ok' with no
errors and warnings. we have the application server start and stop
scripts in place (blank - it's easier to debug that way)
The HACMP service starts on all the 3 nodes - Ok
But when we check the status of the cluster we have
Node1 - up
Pivate interface - up
Public interface - DOWN

Node2 - up
Pivate interface - up
Public interface - DOWN

Node3 - up
Pivate interface - up
Public interface - UP
_______________________
Node1 - ONLINE
Node2 - ONLINE
Node3 - ONLINE
___________________________________
Cluster - UP and STABLE

.............

In the log file we can see that network_down is called by the cluster
manager 5 seconds after cluster starts successfuly on nodes 1 and 2.
The network configuration is as follows - we have ether channel
consisted by 2 physical interfaces - over this ethercannel we have 2
interfaces in 2 different VLANs. the network is checked and it''s
working more over we have that scenario working but in 2 node cluster
even tried with almost mirrored configuration but with no success.
Please any considerations are welcomed, will provide you with more info
tomorrow.

FYI:
After updateing the rsct from 4.5.0 to 4.6.0 (APAR IY84333) the problem
disappeared

Cheers
