Configure Role

This topic describes how to configure a cluster role to make Proficy applications highly available.

About this task

In the following steps, we shall create and configure a role to ensure that the necessary resources and services are highly available.
Remember: Perform steps 1-5 only once on any of the iSCSI initiator nodes. The changes apply to the other nodes in the cluster. For example, if you configure a role on Node1, then there is no need to repeat the process on Node2.

Procedure

  1. Log in to any of the iSCSI initiator nodes.
  2. Launch Failover Cluster Manager.
    Go to Start > Administrative Tools > Failover Cluster Manager.
  3. Create an empty role.
    1. In Failover Cluster Manager, expand your cluster name and go to Storage > Disks.
      The cluster name is the unique name entered when creating a cluster. Refer to Configure Failover Cluster.
    2. Right-click Disks and select Add Disk.
      The Add Disks to a Cluster screen appears.
    3. Select the initialized iSCSI disk you want to add, and select OK.
    4. In Failover Cluster Manager, expand your cluster name and select Roles.
    5. Right-click Roles > Create Empty Role.
      The newly created role appears in the Roles pane with the name New Role.
    6. Right-click New Role and select Properties.
      The New Role Properties screen appears.
    7. Enter a name for the new role. For example, Opshub Role.
      You can assign the role to multiple node servers and set an order of preference.
    8. Select Apply > OK.
  4. Add storage to the newly created (and renamed) empty role.
    1. In Failover Cluster Manager, expand your cluster name and navigate to Storage > Disks.
    2. Right-click Disks > Add Disk.
      The Add Disks to a Cluster screen appears.
    3. Ensure the cluster disk check box is selected and select OK.
      The newly added disk appears in the Disks pane.
    4. Go to Roles, right-click Opshub Role and select Add Storage.
      The Add Storage screen appears.
    5. Select the check box for the storage that is associated to the cluster, and select OK.
  5. Add client access point to the newly created (and renamed) empty role.
    1. Right-click Opshub Role and select Add Resource > Client Access Point.
    2. Complete New Resource Wizard with the following options.
      Section What To Do
      Client Access Point Enter a name. For example, haproficyhub.
      Remember: The client access point is different from the cluster name. It is used by external clients to connect to services provided by the cluster.

      Make a note of this name. You need to provide the fully qualified domain name while installing Operations Hub.

      For example, haproficyhub.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.
  6. Update the hosts file.
    Important: Perform this step on all the nodes - Node1, Node2, NodeX.
    1. Open the hosts file in a text editor.
      ..\Windows\System32\Drivers\etc\hosts
    2. Add the network name and IP address as shown here:

Results

After completing the configuration steps, you should have successfully created and configured a role.
