Configure Role

This topic describes how to configure a highly available virtual machine.

About this task

In failover cluster technology, each highly available virtual machine is considered to be a role.

You can perform the following steps on either Node1 or Node2. Suppose you perform these steps on Node1, they are automatically applied to Node2.

Procedure

  1. Log in to any of the iSCSI initiator nodes.
  2. Go to Start > Administrative Tools > Failover Cluster Manager.
  3. In Failover Cluster Manager, expand your cluster name and go to Storage > Disks.
    The cluster name is the unique name entered when creating your cluster. Refer to step 6 in Create a Cluster.
  4. Right-click Disks and select Add Disk.
    The Add Disks to a Cluster screen appears.
  5. Select the disk you want to add, and select OK.
  6. In Failover Cluster Manager, expand your cluster name and select Roles.
  7. Right-click Roles and select Create Empty Role.
    The newly created role appears in the Roles pane with the name New Role.
  8. Right-click New Role and select Properties.
    The New Role Properties screen appears.
  9. Enter a name for the new role, and select Apply.
    You can assign the role to multiple node servers and set an order of preference.
    For example, the new name is Demo Role.
  10. Right-click Demo Role and select Add Storage.
    The Add Storage screen appears.
  11. Select the storage that is already associated to the cluster, and select OK.
  12. Right-click Demo Role and select Add Resource > Client Access Point.
  13. Complete New Resource Wizard with the following options.
    Section What To Do
    Client Access Point Enter a name. For example, hauaacluster

    Make a note of this name. You need to provide the fully qualified domain name while installing Proficy Authentication. See step 3a in Configure Proficy Authentication Installation. For example, hauaacluster.cluster.ge.com wherein cluster.ge.com is the domain where cluster is installed. Make sure all the initiator nodes are in the same domain name.
    Confirmation The network name and IP address are displayed for confirmation.
    Note: After creating this resource, the IP address and the name should be added to the hosts file on the node servers configured for high availability.
    Configure Client Access Point Verifies the validity of the client access point settings and creates a new resource.
    Summary Select Finish.
    On the node servers configured for high availability, go to ..\Windows\System32\Drivers\etc\hosts and open the file in a text editor to add the network IP address and name as follows.
    <ipaddress>   hauaacluster.cluster.ge.com
         <ipaddress>   hauaacluster

    In the above example, <ipaddress> should be replaced with the actual ip address of your machine.

  14. Right-click Demo Role and select Add Resource > Generic Service.
  15. Complete New Resource Wizard with the following options:
    Section What To Do
    Select Service In the services list, select GE Proficy Authentication Tomcat Web Service.
    Confirmation Skip to the next section.
    Configure Generic Service Skip to the next section.
    Summary Select Finish.
  16. Add the dependency service to role using properties of the added service, so that services restart when switching the node (failover condition).
    1. In Failover Cluster Manager, select the added service.
    2. Select Properties.
      The properties screen for that service appears.
    3. Select the Dependencies tab, and select Insert.

      A row is added to specify our required dependencies.

    4. From the drop-down, select the required resource one by one to be added as part of dependencies.
    5. After inserting the resource, select Apply and then OK.
