Adding a node to an existing cluster
A cluster can consist of up to eight nodes. A dedicated network switch is recommended for
connecting the cluster heartbeat when more than two nodes are used. Alternately, a dedicated
VLAN on an existing switch can be used.
1.
Add the new node to the same domain as the other nodes before adding the new node to
the cluster.
2.
Ensure that the shared storage is connected to the new node and shared LUNs are presented
or exported to the new node.
3.
Record the IP address for the Cluster Internal network. From the Start menu on the desktop,
select Control Panel→Network and Internet→Network and Sharing Center. In the "View your
active networks" section, select Cluster Internal,right-click and select Settings, and then click
Details. . Record the IP address displayed in Autoconfiguration IPv4 Address. Unless the
address has been assigned, the address will be an APIPA IP address, such as 169.X.X.X.
4.
Disconnect the interconnect cable and connect it from Port 1 of the first node to any port on
the switch. Assign the IP address that was recorded in step 3 (for example, 169.X.X.1)
5.
Connect Port 1 of the second node to the next port on the same switch and assign an IP address
(for example, 169.X.X.2).
6.
Connect Port 1 of the new node to the next port on the same switch and assign an IP address
(for example, 169.X.X.3).
7.
From the first node, select the Windows Server Manager icon on the desktop taskbar, and
then select Tools→Failover Cluster Manager.
8.
Existing clusters are displayed in the left navigation pane. Right-click the cluster name and
select Add Node or select the cluster name to view the Add Node option under Configure in
the main viewing pane.
9.
Click Add Node.
The Add Node Wizard opens. Navigate through the wizard to enter the details about the
new node (server IP address or hostname). When finished, the new node is added to the
cluster. All nodes can be joined to the cluster simultaneously. HP recommends that you add
a single node at a time verifying cluster operation with each node addition. Cluster validation
must also be run when each node is added.
