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, 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
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.
See Microsoft Knowledge Base article
KB883398 at the Microsoft Support
website at support.microsoft.com for

The disks on the
shared cluster
storage appear
unreadable or
uninitialized in

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.
No action required.
