Add a New Host to Your NSX-V Deployment

When you add a new host to an existing cluster in your NSX-V environment, a new VM-Series firewall service is deployed on that new host. If you have DRS enabled and to ensure that the no traffic is lost while the VM-Series firewall is coming up, complete the following procedure. You will need to create a temporary cluster to house the new host and disable VMotion until the VM-Series firewall is ready.
  1. Create a temporary cluster and add your new host.
  2. Deploy the VM-Series Firewall service instance on your new host.
  3. Disable vMotion on the virtual switches or distributed switches used by your new host.
    • Virtual Switch
      1. Log in to vCenter Server and select your new host in the inventory.
      2. Select
        Configuration
        Networking
        Virtual Switch
        .
      3. Select the virtual switch that includes the VMkernal port group used by your host and click
        Properties
        Ports
        .
      4. Select the port group configured for VMotion and click
        Edit
        .
      5. On the
        General
        tab, uncheck the
        Enabled
        check box for VMotion.
      6. Click
        OK
        and
        Close
        .
    • Distributed Virtual Switch
      1. Log in to vCenter Server and select your new host in the inventory.
      2. Select
        Configuration
        Distributed Virtual Switch
        .
      3. Select
        Manage Virtual Adapters
        .
      4. Choose the virtual adapter used by your host and click
        Edit
        .
      5. Uncheck
        Use this virtual adapter for VMotion
        .
      6. Click
        OK
        .
  4. Place your new host in maintenance mode.
  5. Move your new host to the existing cluster and exit maintenance mode. Wait for the VM-Series firewall to boot up completely. Because VMotion is disabled on the host, no other virtual machines will be moved to the host by DRS.
  6. When the VM-Series firewall is booted up completely, renable VMotion on the new host. Guest VMs can now move to the new host and security is intact with no traffic lost.
