Configuring DRS Anti-Affinity Rules via PowerCLI

You can also configure DRS anti-affinity rules using PowerCLI. To configure via PowerCLI, you will need to ensure PowerCLI has been deployed and installed locally on your system. Perform the following steps to configure the DRS rules via PowerCLI:

1. Open the PowerCLI terminal up.
2. Type Connect-VIServer -Server VCENTER_SERVER, which will connect your PowerCLI session to the vCenter server you are working on.

3. Next, we want to retrieve the NSX controller virtual machines and store it as a variable, $nsx_controllers, using the get-vm PowerCLI cmdlet. The following code snippet demonstrates the command:

$nsx_controllers = get-vm | ? {$_.name -like "NSX_Controller*"}  

4. Next, using the New-DRSRule cmdlet, we will configure the anti-affinity DRS rule on the RegionA01-MGMT01 vSphere cluster using the following command:

New-DrsRule -Name nsx-controller-anti-affinity -Cluster RegionA01-MGMT01 -KeepTogether $false -VM $antiAffinityVMs
