The procedures for expanding cluster capacity with additional vSAN Ready Node hardware are similar to the procedures performed initially to build the cluster.

Prerequisites

Verify that you have met the prerequisites described in Expanding the Existing vSAN Ready Node Cluster with Additional Nodes.

Procedure

  1. In the vSphere Web Client, select VRN-DC and Add Host.
  2. Add the new ESXi hosts to the data center.
    Note:

    FQDNs must be used when adding the ESXi hosts.

  3. Under dvSwitch0, select Add and Manage Hosts and perform the following steps.
    1. Select task > Add hosts.
    2. Select New hosts and then select all hosts listed.
    3. Select network adapter tasks > Manage physical adapters.
    4. Manage physical adapters - for each ESXi host, select the vmnic that is not in use, select Assign uplink, and use Uplink 2.
  4. Migrate VMkernel interfaces to the DVS.
    1. In the vSphere Web Client, under Distributed Switches select Add and Manage Hosts.
    2. Select task > Manage host networking.
    3. Select Attached hosts and then select all the newly created attached hosts.
    4. Select network adapter tasks > Manage VMkernel adapters.
    5. Manage VMkernel network adapters - for each ESXi host, select vmk0, then select Assign port group > dvpg-vmk0-management.
  5. On the newly created hosts, remove vSwitch0 from all nodes

    [root@esxi-01:~] esxcli network vswitch standard portgroup remove --portgroup-name="VM Network" --vswitch-name=vSwitch0

    [root@esxi-01:~] esxcli network vswitch standard uplink remove --uplink-name=vmnic4 --vswitch-name=vSwitch0

    [root@esxi-01:~] esxcli network vswitch standard remove --vswitch-name=vSwitch0

  6. On the newly created hosts, add a second physical network adapter to the DVS.
    1. In the vSphere Web Client, under Distributed Switches, select Add and Manage Hosts.
    2. Select task > Manage host networking.
    3. Select Attached hosts and then select all attached hosts.
    4. Select network adapter tasks > Manage physical adapters.
    5. Manage physical network adapters - for each ESXi host, select the vmnic that is not in use, then select Assign uplink and use Uplink 1.
  7. On the newly created hosts, add VMkernel adapters for vSphere vMotion and vSAN.
    1. In the vSphere Web Client, under Distributed Switches, select Add and Manage Hosts.
    2. Select task > Manage host networking.
    3. Select Attached hosts and then select the newly attached hosts.
    4. Select network adapter tasks > Manage VMkernel adapters.
    5. Under Manage VMkernel network adapters, perform the following tasks.
      1. On the first new ESXi host, select New adapter.

      2. Select target device - Select an existing network and select dvpg-vmk1-VSAN.

      3. Port properties - enable Vrtual SAN traffic only.

      4. IPv4 settings - Set the static IP address to match that of the new host and set the netmask to 255.255.255.0.

        Note:

        This action applies to the recently added vSAN IPv4 address and vSphere vMotion addresses, respectively.

      5. Select New adapter again.

      6. Select target device - Select an existing network and select dvpg-vmk2-vMotion.

      7. Port properties - enable vMotion traffic only.

      8. IPv4 settings - Set the static IP address to match that of the new host and set the netmask to 255.255.255.0.

        Note:

        This action applies to the recently added vSAN IPv4 address and vSphere vMotion, respectively.

      9. Repeat the preceding instructions for all remaining hosts.

    6. Click Next on the following pages and then click Finish.
