Dell PowerEdge Cluster SE500W Installation And Troubleshooting Manual page 89

Table A-1. General Cluster Troubleshooting (continued)
Problem
You are prompted to configure
one network instead of two
during MSCS installation.
Client systems are dropping off
of the network while the cluster
is failing over.
Only one network segment
appears during Cluster Service
installation.
Probable Cause
The TCP/IP configuration is
incorrect.
The private (point-to-point)
network is disconnected.
With MSCS, the service
provided by the recovery
group becomes temporarily
unavailable to clients during
failover. Clients may lose
their connection if their
attempts to reconnect to the
cluster are too infrequent or
if they end too abruptly.
Public and private networks
segments are not unique.
Corrective Action
The node-to-node network and public
network must be assigned static IP
addresses on different subnets. See
"Assigning Static IP Addresses to Your
Cluster Resources and Components" for
information about assigning the
network IPs.
Ensure that both systems are powered on
so that both network adapters in the
private network are available.
The time that the service is temporarily
unavailable varies depending on the
application. Contact the application
program vendor for more information.
Place all installed network adapters in a
cluster node on separate IP networks.
Ensure that the same network segments
that were used for each network adapter
are identical on the second cluster node.
