Before adding a node to a cluster, install VCS on the node as follows:
In case of VCS for Windows, refer to the Symantec Cluster Server for Windows Installation and Upgrade Guide.
In case of Storage Foundation and High Availability for Windows (SFW HA), refer to the Symantec Storage Foundation and High Availability Solutions Installation and Upgrade Guide.
The VCS Cluster Configuration Wizard (VCW) configures VCS components and starts VCS services on the new node. The wizard does not configure any service groups on the new node.
To add a node to a VCS cluster
Run the wizard from the node to be added or from a node in the cluster. The node that is being added should be part of the domain to which the cluster belongs.
To discover information about all the systems and users in the domain, do the following:
Clear the Specify systems and users manually check box.
Click Next.
Proceed to step 8.
To specify systems and user names manually (recommended for large domains), do the following:
Check the Specify systems and users manually check box.
Additionally, you may instruct the wizard to retrieve a list of systems and users in the domain by selecting appropriate check boxes.
Click Next.
If you chose to retrieve the list of systems, proceed to step 6. Otherwise proceed to the next step.
Type the name of an existing node in the cluster and click Add.
Type the name of the system to be added to the cluster and click Add.
If you specify only one node of an existing cluster, the wizard discovers all nodes for that cluster. To add a node to an existing cluster, you must specify a minimum of two nodes; one that is already a part of a cluster and the other that is to be added to the cluster.
Proceed to step 8.
Enter the system name and click Add to add the system to the Selected Systems list. Alternatively, you can select the systems from the Domain Systems list and click the right-arrow icon.
If you specify only one node of an existing cluster, the wizard discovers all nodes for that cluster. To add a node to an existing cluster, you must specify a minimum of two nodes; one that is already a part of a cluster and the other that is to be added to the cluster.
A system can be rejected for any of the following reasons:
The system does not respond to a ping request.
WMI access is disabled on the system.
The wizard is unable to retrieve information about the the system's architecture or operating system.
VCS is either not installed on the system or the version of VCS is different from what is installed on the system on which you are running the wizard.
Click on a system name to see the validation details. If you wish to include a rejected system, rectify the error based on the reason for rejection and then run the wizard again.
Click Next to proceed.
If you chose to specify the systems manually in step 4, only the clusters configured with the specified systems are displayed.
In the Cluster User Information dialog box, type the user name and password for a user with administrative privileges to the cluster and click OK.
The Cluster User Information dialog box appears only when you add a node to a cluster with VCS user privileges (a cluster that is not a secure cluster).
The right pane lists nodes that are part of the cluster. The left pane lists systems that can be added to the cluster.
If a node does not get validated, review the message associated with the failure and restart the wizard after rectifying the problem.
Do one of the following:
To configure the VCS private network over Ethernet, do the following:
Select the check boxes next to the two NICs to be assigned to the private network.
Symantec recommends reserving two NICs exclusively for the private network. However, you could lower the priority of one NIC and use the low-priority NIC for public and private communication.
If you have only two NICs on a selected system, it is recommended that you lower the priority of at least one NIC that will be used for private as well as public network communication.
To lower the priority of a NIC, right-click the NIC and select Low Priority from the pop-up menu.
If your configuration contains teamed NICs, the wizard groups them as "NIC Group #N" where "N" is a number assigned to the teamed NIC. A teamed NIC is a logical NIC, formed by grouping several physical NICs together. All NICs in a team have an identical MAC address. Symantec recommends that you do not select teamed NICs for the private network.
The wizard configures the LLT service (over Ethernet) on the selected network adapters.
To configure the VCS private network over the User Datagram Protocol (UDP) layer, do the following:
Select the check boxes next to the two NICs to be assigned to the private network. You can assign maximum eight network links. Symantec recommends reserving at least two NICs exclusively for the VCS private network. You could lower the priority of one NIC and use the low-priority NIC for both public and private communication.
If you have only two NICs on a selected system, it is recommended that you lower the priority of at least one NIC that will be used for private as well as public network communication. To lower the priority of a NIC, right-click the NIC and select Low Priority from the pop-up menu.
Specify a unique UDP port for each of the link. Click Edit Ports if you wish to edit the UDP ports for the links. You can use ports in the range 49152 to 65535. The default ports numbers are 50000 and 50001 respectively. Click OK.
For each selected NIC, verify the displayed IP address. If a selected NIC has multiple IP addresses assigned, double-click the field and choose the desired IP address from the drop-down list. In case of IPv4, each IP address can be in a different subnet.
The IP address is used for the VCS private communication over the specified UDP port.
For each selected NIC, double-click the respective field in the Link column and choose a link from the drop-down list. Specify a different link (Link1 or Link2) for each NIC. Each link is associated with a UDP port that you specified earlier.
The wizard configures the LLT service (over UDP) on the selected network adapters. The specified UDP ports are used for the private network communication.
This step is applicable only if you have configured the ClusterService service group, and the system being added has multiple adapters. If the system has only one adapter for public network communication, the wizard configures that adapter automatically.
