Managing Azure instances

This section describes the common maintenance tasks for stopping, restarting and permanently removing Conferencing Node Azure instances.

Temporarily removing (stopping) a Conferencing Node instance

At any time you can temporarily remove a Conferencing Node instance from your Pexip Infinity platform if, for example, you do not need all of your current conferencing capacity.

To temporarily remove a Conferencing Node instance:

  1. Put the Conferencing Node into maintenance mode via the Pexip Infinity Administrator interface on the Management Node:
    1. Go to Platform configuration > Conferencing Nodes.
    2. Select the Conferencing Node.

    3. Select the Enable maintenance mode check box and select Save.

      While maintenance mode is enabled, this Conferencing Node will not accept any new conference instances.

    4. Wait until any existing conferences on that Conferencing Node have finished. To check, go to Status > Conferences.
  2. Stop the Conferencing Node instance on Azure:
    1. From the Azure portal, select Virtual machines to see the status of all of your instances.
    2. Select the instance you want to shut down.
    3. Select Stop to shut down the instance.

Reinstating (restarting) a stopped Conferencing Node instance

You can reinstate a Conferencing Node instance that has already been installed but has been temporarily shut down.

To restart a Conferencing Node instance:

  1. Restart the Conferencing Node instance on Azure:
    1. From the Azure portal, select Virtual machines to see the status of all of your instances.
    2. Select the instance you want to restart.
    3. Select Start to start the instance.

  2. Take the Conferencing Node out of maintenance mode via the Pexip Infinity Administrator interface on the Management Node:

    1. Go to Platform configuration > Conferencing Nodes.
    2. Select the Conferencing Node.
    3. Clear the Enable maintenance mode check box and select Save.

  3. Update the Conferencing Node's static NAT address, if appropriate.

    If your Conferencing Node instance was configured with an auto-assigned public IP address, it will be assigned a new public IP address when the instance is restarted.

    1. Go to Platform configuration > Conferencing Nodes and select the Conferencing Node.
    2. Configure the Static NAT address as the instance's new public IP address.

After reinstating a Conferencing Node, it takes approximately 5 minutes for the node to reboot and be available for conference hosting, and for its last contacted status to be updated on the Management Node.

Permanently removing a Conferencing Node instance

If you no longer need a Conferencing Node instance, you can permanently delete it from your Pexip Infinity platform.

To remove a Conferencing Node instance:

  1. If you have not already done so, put the Conferencing Node into maintenance mode via the Pexip Infinity Administrator interface on the Management Node:
    1. Go to Platform configuration > Conferencing Nodes.
    2. Select the Conferencing Node.

    3. Select the Enable maintenance mode check box and select Save.

      While maintenance mode is enabled, this Conferencing Node will not accept any new conference instances.

    4. Wait until any existing conferences on that Conferencing Node have finished. To check, go to Status > Conferences.
  2. Delete the Conferencing Node from the Management Node:
    1. Go to Platform configuration > Conferencing Nodes and select the Conferencing Node.
    2. Select the check box next to the node you want to delete, and then from the Action drop-down menu, select Delete selected Conferencing Nodes and then select Go.
  3. Terminate the Conferencing Node instance on Azure:
    1. Delete the resource group which holds the instance:
      1. From the Azure Portal, select Resource groups to see all of your resource groups.
      2. Select the resource group you want to delete.
      3. Select Delete to delete the resource group.
    2. Delete the storage container which holds the instance disk:
      1. From the Azure Portal, select All resources to see all of your storage accounts.
      2. Select the storage account that is being used to store the instance disk.
      3. Under Services, select Blobs to see all of the storage containers in the storage account.
      4. Select the storage container you want to delete.
      5. Select Delete to delete the storage container.
    3. If boot diagnostics were enabled on the VM instance, delete the storage container which holds the instance boot diagnostics logs:
      1. From the Azure Portal, select All resources to see all of your storage accounts.
      2. Select the storage account that is being used to store the boot diagnostics logs.
      3. Under Services, select Blobs to see all of the storage containers in the storage account.
      4. Select the storage container you want to delete.
      5. Select Delete to delete the storage container.
