Cluster x does not appear to have a dedicated heartbeat network connection. - Unterschiedliche Aussagen in Cluster/Exchangedokumentation von Microsoft

Guten Morgen,

nachdem ich gerade in den letzten Zuegen der Migration auf Exchange 2007 CCR
bin verwundert mich nun der Healthcheck ein wenig.
Der Cluster laeuft, jedoch Mecker der ExBPA die Heartbeat-Config an:

Dedicated Heartbeat:
Cluster DEFRA-EX1MBX1 does not appear to have a dedicated heartbeat network
connection. This may cause reliability problems.

so weit so gut, man folge der Anleitung: Tell me more about the issue and
how to resolve it.

The Microsoft® Exchange Server Analyzer Tool reads the following registry
entry to determine the defined role for each network interface resource in
the Exchange server cluster:
HKEY_LOCAL_MACHINE\Cluster\Networks\<NetworkInterfaceGUID>\Role

A value of 1 indicates the network resource has been configured as a
dedicated private (heartbeat) network. A value of 2 indicates the network
resource has been configured as a dedicated public network (client access).
A value of 3 indicates the network resource has been configured as a mixed
network that allows both heartbeat traffic and client access traffic.

The Exchange Server Analyzer queries the Win32_Service Microsoft Windows®
Management Instrumentation (WMI) class to determine the value of the Started
key for the Cluster service (ClusSvc). A value of True indicates the Cluster
service is started and a value of False indicates the Cluster service is not
running.

If the Exchange Server Analyzer does not find a network resource in an
Exchange cluster configured as a dedicated private network, a warning is
displayed.

Configuring a dedicated private network to use for the cluster heartbeat is
a recommended best practice for all Exchange Server clusters. Communication
between nodes is critical for smooth cluster operations. You must configure
the networks that you use for cluster communication optimally and follow all
hardware compatibility list requirements. For networking configuration, two
or more independent networks must connect the nodes of a cluster to avoid a
single point of failure. Using two local area networks is typical. Microsoft
Product Support Services does not support the configuration of a cluster
with nodes connected by only one network.

To correct this warning
1.. If not already present, add network interface cards to each node in
the Exchange cluster and configure the network interface cards as a private
network in Cluster Administrator.

2.. If additional network cards are present but being used for mixed
networks, you should modify the configuration by re-configuring the
appropriate networks to act as a dedicated private network.

For more information about cluster heartbeat networks, see the following
Microsoft Knowledge Base articles:

a.. 258750, "Recommended Private "Heartbeat" Configuration on a Cluster
Server" (http://go.microsoft.com/fwlink/?lin...;kbid%8750)

Unter HKEY_LOCAL_MACHINE\Cluster\Networks\<NetworkInterfaceGUID>\Role zeigt
meine NIC tatsaechlich einen Wert von 3 an. OK, hier scheint der Fehler zu
stecken... welcher im Kaffeewahn dummerweise uebersehen wurde...

Nun verweist MS jedoch noch auf KB258750. Wenn man diese KB Artikel mit "How
to Configure Network Connections for Cluster Continuous Replication"
(http://technet.microsoft.com/en-us/...y/aa997910(EXCHG.80).aspx)
vergleicht wird man schnell feststellen dass es hier Unterschiede gibt.

Ein Beispiel:

KB258750:
13. Vergewissern Sie sich, dass auf der Registerkarte WINS keine Werte
definiert sind. Klicken Sie auf NetBIOS über TCP/IP deaktivieren.


"http://technet.microsoft.com/en-us/...y/aa997910(EXCHG.80).aspx":
09 .How to Configure Network Connections for Cluster Continuous
Replication:n the WINS tab, ensure that Disable NetBIOS over TCP/IP is not
selected.

Wenn man KB258750 auf Englisch uebersetzen laesst (normalerweise sowieso
meine Sprache) gibt es im Punkt 13. kein Disable NetBios...

Gruss,
Wolfgang

Pardon,
ich muss meine Aussage revidieren.
Ich war in den Zeilen hoch zum Public gerutscht.

Auch unter:
http://technet.microsoft.com/en-us/...y/aa997910(EXCHG.80).aspx

steht:
On the WINS tab, ensure that Disable NetBIOS over TCP/IP is selected.

Gruss
