Public network clients
cannot access the
applications or services
that are provided by
the cluster.
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 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.
Virtual Disks fail over
continuously between
the two storage
controllers when a
storage path fails.
The failback mode for the
cluster node(s) is not set
properly.
Set the correct failback mode on
each cluster node: you must
merge the PowerVault MD3000i
Stand Alone to Cluster.reg file
located in the windows\utility
directory of the Dell PowerVault
MD3000i Resource CD into the
registry of each node.
Virtual Disk Copy
operation fails.
The Virtual Disk Copy
operation uses the cluster
disk as the source disk.
To perform a Virtual Disk Copy
operation on the cluster share
disk, create a snapshot of the
disk, and then perform a Virtual
Disk Copy of the snapshot
virtual disk.
