Completing the Configuration

After you have created the SplitSite configuration, change the quorum service port, if necessary. Then, enable quorum within the everRun Availability Console. Finally, verify the configuration and (re-)join VMs.

Prerequisite: Plan and create a SplitSite configuration by first reading Creating a SplitSite Configuration and following its instructions, if you have not already done so.
Note: The port configured for quorum service on the quorum computer and the port configured for the quorum server within the everRun Availability Console must be the same port numbers. If you change the quorum service ports on the quroum computer, you must change the quorum service ports on all everRun systems (using the everRun Availability Console) that connect to that quorum computer so that both the quorum computer and the everRun systems use the same port numbers. See Configuring the Quorum Server Within the everRun Availability Console.

Configuring the Quorum Service Port

By default, the quorum service listens on UDP port 4557.

In most cases, you do not need to change the default port. However, you can change the port, if the network configuration requires you to:

To change the port number on the quorum server

  1. Log on to the quorum computer using an account with administrative privileges.

  2. Open a command window in administrative mode.

  3. Stop the quorum service by typing:

    net stop sraqserver

  4. Change the port by typing (replacing nnnn with the new port number):

    sraqserver -install nnnn

  5. Restart the quorum service by typing:

    net start sraqserver

Verifying the Quorum Service Port

If you need to verify the quorum service port, check this Windows registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SraQserver\Parameters\QSServerPortForReceive

Configuring the Quorum Server Within the everRun Availability Console

Once the quorum service is running, you should enable the quorum service within the everRun Availability Console. You can also remove a quorum server.

To enable the quorum service:

  1. Login to the everRun Availability Console with an account that has administrative privileges.
  2. Click Preferences in the left-hand navigation panel, to open the Preferences page.
  3. Click Quorum Servers. The quorum configuration page opens.
  4. Click Add Quorum Server at the left side of the page.
  5. In the Add Preferred Quorum Server dialog box, enter the following values (if a preferred quorum server already exists, the Add Alternate Quorum Server dialog box appears):
    • DNS or IP Address—Type the fully-qualified DNS host name or IP address for the preferred quorum server.

    • Port —The default port is 4557. Type a port number if you need a port that is different from the default. You need to type only one port number. The quorum service will open the port number for Port and the next port (for example, 4557 and 4558)

      Note: The port number must match the port that the quorum service is listening on. (If necessary, you can change the port on the quorum server.)

    Click Save to save the values.

  6. Repeat steps 4 and 5 to configure a second, alternate quorum server. Stratus recommends configuring two quorum servers.
  7. To enable quorum service, select the Enabled check box and click Save.

Changes to the quorum configuration do not effect running VMs. You must stop and restart any running VMs after changing the quorum configuration.

To remove a quorum server

Caution: If you remove the preferred quorum server, the alternate quorum server becomes the preferred quorum server. If no alternate quorum server exists, removing the preferred quorum server automatically disables quorum service.
  1. Navigate to the Preferences page of the everRun Availability Console.
  2. Click Quorum Servers.
  3. Locate the entry for the quorum server you want to remove.
  4. In the right-most column, click Remove.
Note: If a VM is using the quorum server that you are removing, you must reboot the VM so that it no longer recognizes the quorum server, which allows the removal process to finish. The VM will downgrade to simplex mode until it is restarted with no quorum servers configured.

Verify the Configuration and (Re-)Join VMs

Verify the configuration and (re-)join VMs. Follow the appropriate steps in From Initial Installation to Completing the SplitSite Configuration.
