Configuring VCS components

Applications configured using GenericService or Process resources may require network components or registry replication resources. You can configure these VCS components only for service groups created using the wizard.

Note:

Configure these components only after configuring all application resources. The wizard creates a service group after these components are configured. To add more application resources, you must rerun the wizard in the Modify mode.

To configure VCS components

  1. In the Application Options panel, click Configure Other Components.
  2. Select the VCS component to be configured for your applications.

    The available options are as follows:

    • Registry Replication Component: Select this option to configure registry replication for your application. To configure a Registry Replication resource, proceed to step 3.

    • Network Component: Select this option to configure network components for your application. If you wish to configure a virtual computer name, check Lanman component also. To configure a network resource, proceed to step 5.

    The wizard does not enable the Lanman Component check box unless the Network Component check box is checked.

  3. Specify the registry keys to be replicated.

    The RegistryReplication dialog box appears only if you chose to configure the Registry Replication Component in the Application Component dialog box.

    • Specify the directory on the shared disk in which the registry changes are logged.

    • Click Add.

    • In the Registry Keys dialog box, select the registry key to be replicated.

    • Click OK. The selected registry key is added to Registry KeyList box.

    • This is applicable in case of VCS for Windows only.

      Check the Configure NetApp SnapMirror Resource(s) check box if you want to set up a disaster recovery configuration. The SnapMirror resource is used to monitor replication between filers at the primary and the secondary site, in a disaster recovery configuration. Note that you must configure the SnapMirror resource only after you have configured the cluster at the secondary site.

    • Click Next.

    If you chose Network Component from the Application Component dialog box, proceed to the next step. Otherwise, proceed to step 6.

  4. This step is applicable in case of VCS for Windows only.

    On the Initiator Selection panel, select the initiator for the virtual disk from the list of available initiators displayed for each cluster node, and then click Next.

    If you are configuring multipath I/O (MPIO) over Fibre Channel (FC), you must select at least two FC initiators for each cluster node. Note that the node from which you run this wizard already has an initiator selected by default. This is the initiator that was specified when you connected the LUNs to this cluster node.

  5. The Virtual Computer Configuration dialog box appears only if you chose to configure the Network Component in the Application Component dialog box.

    Specify the network related information as follows:

    • Select IPv4 to configure an IPv4 address for the virtual server.

      • In the Virtual IP Address field, type a unique virtual IPv4 address for the virtual server.

      • In the Subnet Mask field, type the subnet to which the virtual IPv4 address belongs.

    • Select IPv6 to configure an IPv6 address for the virtual server. The IPv6 option is disabled if the network does not support IPv6.

      • Select the prefix from the drop-down list. The wizard uses the prefix and automatically generates an IPv6 address that is valid and unique on the network.

    • In the Virtual Server Name field, enter a unique virtual computer name by which the node will be visible to the other nodes.

      The virtual name must not exceed 15 characters. Note that the Virtual Computer Name text box is displayed only if you chose to configure the Lanman Component in Application Component dialog box.

    • For each system in the cluster, select the public network adapter name. To view the adapters associated with a system, click the Adapter Display Name field and click the arrow.

      Note that the wizard displays all TCP/IP enabled adapters on a system, including the private network adapters, if applicable. Ensure that you select the adapters assigned to the public network, not the private.

    • Click Advanced and then specify additional details for the Lanman resource as follows:

      • Check AD Update required to enable the Lanman resource to update the Active Directory with the virtual name.

        This sets the Lanman agent attributes ADUpdateRequired and ADCriticalForOnline to true.

      • In the Organizational Unit field, type the distinguished name of the Organizational Unit for the virtual server in the format CN=containername,DC=domainname,DC=com.

        To browse for an OU, click ... (ellipsis button) and search for the OU using the Windows Find Organization Units dialog box. By default, the Lanman resource adds the virtual server to the default container "Computers."

        The user account for VCS Helper service must have adequate privileges on the specified container to create and update computer accounts.

      • Click OK.

    • Click Next.

  6. In the Application Options dialog box, select one of the following options:

    • To configure additional VCS components, repeat step 1 through step 5.

    • To configure a GenericService resource:

    • To configure a Process resource:

    • To configure a Service Monitor resource:

    If you do not want to add any more resources, proceed to configuring the service group:
