Table A-1. General Cluster Troubleshooting (continued)
Problem
Unable to add a node to
the cluster.
The disks on the shared
cluster storage appear
unreadable or
uninitialized in
Windows Disk
Administration
Probable Cause
The new node cannot
access the shared
disks.
The shared disks are
enumerated by the
operating system
differently on the
cluster nodes.
One or more nodes
may have the Internet
Connection Firewall
enabled, blocking
RPC communications
between the nodes.
This situation is
normal if you stopped
the Cluster Service. If
you are running
Windows Server 2003,
this situation is
normal if the cluster
node does not own the
cluster disk.
Corrective Action
Ensure that the new cluster
node can enumerate the cluster
disks using Windows Disk
Administration. If the disks do
not appear in Disk
Administration, check the
following:
• Check all cable connections
• Check all zone configurations
• Check the LUN Settings. Use
the "Advanced" with
"Minimum" option
Configure the Internet
Connection Firewall to allow
communications that are
required by the MSCS and the
clustered applications
or services.
