Table A-1. General Cluster Troubleshooting (continued)
Problem
Unable to add a node
to the cluster.
The disks from one of
the cluster nodes 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 Access Control
settings on the attached
storage systems
• Use the Advanced with
Minimum option.
Configure the Internet
Connection Firewall to allow
communications that are
required by the Microsoft
Cluster and the clustered
applications or services. See
Microsoft Knowledge Base article
KB883398 at the Microsoft
Support website at
support.microsoft.com for more
information.
No action required.
