You can run the migration coordinator tool with only one NSX Manager appliance deployed. However, deploy two additional NSX Manager appliances before you use your NSX-T Data Center environment in production.

Important: Install the NSX Manager appliances on ESXi hosts that are not part of the NSX for vSphere environment that is migrating.

After the new nodes are deployed, these nodes connect to the parent NSX Manager node to form a cluster. The recommended number of clustered NSX Manager nodes is three.

All the repository details of the parent NSX Manager node are synchronized with the newly deployed nodes in the cluster.

Prerequisites

  • Verify that a parent NSX Manager node is installed.
  • Verify that compute manager is configured. See Add a Compute Manager.

Procedure

  1. From a browser, log in with admin privileges to an NSX Manager at https://<nsx-manager-ip-address>.
  2. Select System > Overview > Add Nodes.
  3. Enter the NSX Manager common attribute details.
    Option Description
    Compute Manager Registered resource compute manager is populated.
    Enable SSH Toggle the button to allow an SSH login to the new NSX Manager node.
    Enable Root Access Toggle the button to allow the root access to the new NSX Manager node.
    CLI Username and Password Confirmation

    Set the CLI password and password confirmation for the new node.

    Your password must comply with the password strength restrictions.
    • At least 12 characters
    • At least one lower-case letter
    • At least one upper-case letter
    • At least one digit
    • At least one special character
    • At least five different characters
    • No dictionary words
    • No palindromes
    • More than four monotonic character sequence is not allowed

    The CLI username is already set to admin.

    Root Password and Password Confirmation

    Set the root password and password confirmation for the new node.

    Your password must comply with the password strength restrictions.
    • At least 12 characters
    • At least one lower-case letter
    • At least one upper-case letter
    • At least one digit
    • At least one special character
    • At least five different characters
    • No dictionary words
    • No palindromes
    • More than four monotonic character sequence is not allowed
    DNS Servers Enter the DNS server IP address available in the vCenter Server.
    NTP Servers Enter the NTP server IP address.
  4. Enter the NSX Manager node details.
    Option Description
    Name Enter a name for the NSX Manager node.
    Cluster Designate the cluster the node is going to join from the drop-down menu.
    Resource Pool or Host Assign either a resource pool or a host for the node from the drop-down menu.
    Datastore Select a datastore for the node files from the drop-down menu.
    Network Assign the network from the drop-down menu.
    Management IP/Netmask Enter the IP address and netmask.
    Management Gateway Enter the gateway IP address.
  5. (Optional) Click New Node and configure another node.
    Repeat steps 3-4.
  6. Click Finish.
    The new nodes are deployed. You can track the deployment process on the System > Overview page or the vCenter Server.

    The deployment, cluster formation, and repository synchronization might take up to 10 minutes.

  7. After the NSX Manager boots, log in to the CLI as admin and run the get interface eth0 command to verify that the IP address was applied as expected.
  8. Enter the get services command to verify that all the services are running.
    If the services are not running, wait for all the services to start running.
  9. Log in to the parent NSX Manager node and enter the get cluster status command to verify that the nodes are successfully added to the cluster.
  10. Verify that your NSX Manager has the required connectivity.
    Make sure that you can perform the following tasks.
    • Ping your NSX Manager from another machine.
    • The NSX Manager can ping its default gateway.
    • The NSX Manager can ping the hypervisor hosts that are in the same network as the NSX Manager using the management interface.
    • The NSX Manager can ping its DNS server and its NTP server.
    • If you enabled SSH, make sure that you can SSH to your NSX Manager.

    If connectivity is not established, make sure that the network adapter of the virtual appliance is in the proper network or VLAN.
