Step 5

Click Next.

Step 6

Step 7

In the Create a Block of MAC Addresses dialog box, complete the following fields:

Step 8

Click OK.

Step 9

Click Finish.

Step 1

Log in to the command line of each ESX Server.

Step 2

Create three vSwitches on each ESX server using the listed names.

Step 3

Use the following CLI commands to create the three new vSwitches:

Step 4

The default vSwitch vSwitch0 created during installation of ESXi needs to be renamed to vswitch-hx-inband-mgmt for the Hx Data Platform node set up scripts to work properly. Use the following command to rename the switch and then reboot the host so that the vmkernel re-reads its configuration file to use the new name.

Step 5

You can verify the creation and renaming of the vSwitches after a host reboot with the following command:

Step 1

From vCenter, create DVS Switch and port groups.

1. Select vCenter Inventory Lists > Datacenters > datacenter > Related Objects > Distributed Switches . Click Add Distributed Switch icon.

2. Complete the New Distributed Switch wizard. Create each DVS switch with two uplinks.

   For example: VM network and vmotion pg

   • DVSwitch-VMNetwork: DVPortGroup-VMNetwork

   • DVSwitch-Vmotion: DVPortGroup-Vmotion

Step 2

Migrate the vSwitch, VMNetwork. Perform the following steps to migrate VMNetwork from legacy vSwitch to DVS.

1. Select vCenter Inventory Lists > Datacenters > datacenter > Related Objects > Distributed Switches.

2. Select the DVSwitch-VMNetwork vSwitch. Click the Add and Manage Hosts icon. This starts the Add and Manage Hosts wizard.

3. On the Select task page, select Add Hosts. Click Next.

4. On the Select hosts page, click Add New Hosts. Select all hosts in the cluster. Click Next.

5. On the Select network adapter tasks page, select Manage physical adapters and Migrate virtual machine networking. Click Next.

6. On the Manage physical network adapters page, the physical adapters part of vswitch-hx-vm-network:VM Network are assigned to the DVSwitch-VMNetwork.

7. Under the On other switches/unclaimed list, select the vmnic corresponding to the In Use by Switch, vswitch-hx-vm-network.

8. Click Assign uplink.

9. Select Auto-assign.

10. Click OK. The page refreshes with the newly assigned vmnic listed under On this switch.

11. The Analyze impact page shows the impact of this migration. Verify the impact is all green. Click Next.

12. On the Migrate VM networking page, select the VMs to migrate to the new network, DVPortGroup-VMNetwork.

    Next

    Select all the VMs, except the controller VMs, stCtlVM, from all the hosts. Select the DVPortGroup-VMNetwork. Click Next.

    Note	The list of VMs for each host includes all the VMs, including the controller VMs. DO NOT select any controller VMs. Migrating the controller VMs will break your storage cluster.

13. On the Ready to complete page, confirm the summary of the migration. Click Finish.

    Note	Post migration system generates several network related alarms. Verify and clear the alarms.

Step 3

Migrate the vSwitch to vmotion pg. Perform the following steps to migrate vmotion pg from legacy vSwitch to DVS.

1. Select vCenter Inventory Lists > Datacenters > datacenter > Related Objects > Distributed Switches.

2. Select the DVSwitch-Vmotion vSwitch. Click the Add and Manage Hosts icon. This starts the Add and Manage Hosts wizard.

3. On the Select task page, select Add Hosts. Click Next.

4. On the Select hosts page, click Add New Hosts. Select all hosts in the cluster. Click Next.

5. On the Select network adapter tasks page, select the tasks Manage physical adapters and Manage VMkernel adapters. Click Next.

6. On the Manage physical network adapters page, the physical adapters part of vmotion:vmotion pg are assigned to the DVSwitch-Vmotion.

   Under the On other switches/unclaimed list, select the vmnic corresponding to the In Use by Switch, vmotion. Click Assign uplink, select Auto-assign, and click OK. The page refreshes with the newly assigned vmnic listed under On this switch. Click Next.

7. On the Manage VMkernel network adapters page, migrate the VMkernel adapter to the port group, DVPortGroup-Vmotion.

   For each host, under the On other switches list, select the VMKernel adapter corresponding to the In Use by Switch, vmotion. Click Assign port group. Select the destination port group, DVPortGroup-Vmotion. Click OK. The page refreshes with the Reassigned VMkernel network adapters, listing the Source Port Group and Destination Port Group.

8. Select the hosts to migrate to the new network, DVPortGroup-Vmotion. Click Next.

9. On the Ready to complete page, confirm the summary of the migration, click Finish.

Step 4

Post migration step. Verify there is no impact on the VMs with respect to IO, Network connectivity and VM Migration.
