You are prompted
to configure one
network instead of
two during MSCS
installation.
The TCP/IP
configuration
is incorrect.
The node-to-node network and public
network must be assigned static
IP addresses on different subnets.
For more information about assigning
the network IPs, see "Assigning Static
IP Addresses to Cluster Resources and
Components" of the Dell Failover
Clusters with Microsoft Windows Server
2008 Installation and Troubleshooting
Guide at support.dell.com/manuals.
The private
(point-to-point)
network is
disconnected.
Ensure that all systems are powered on
so that the NICs in the private network
are available.
Unable to add a
node to the cluster.
The new node cannot
access the shared
disks.
The shared disks are
enumerated by the
operating system
differently on the
cluster nodes.
Ensure that the new cluster node can
enumerate the cluster disks using
Windows Disk Administration. If the
disks do not appear in Disk
Administration, do the following:
1 Check all cable connections.
2 Check all zone configurations.
3 Use the Advanced with
Minimum option.
One or more nodes
may have the Internet
Connection Firewall
enabled, blocking
RPC communications
between the nodes.
Configure the Internet Connection
Firewall to allow communications that
are required by the MSCS and the
clustered applications or services. For
more information, see the Microsoft
Knowledge Base article KB883398 at
support.microsoft.com.
