Cmdlets are usually implemented around resource operations. The four basic operations are CREATE, READ, UPDATE and DELETE. This set of operations is known as CRUD. Most of the cmdlets support CRUD which are respectively cmdlets that start with the New/Get/Set/Remove cmdlet verbs but they also may have additional operations

Step 1: Retrieve a object by running a Get command

You can READ objects by using Get-DrsClusterGroup cmdlet. See example below: 
# Retrieves the corresponding DRS cluster groups associated with any of the virtual machines from the specified list.
Get-DrsClusterGroup -VM $vm1, $vm2

Step 2 : Run commands from the CRUD group

You can CREATE objects by using New-DrsClusterGroup cmdlet. See example below: 
# Creates a VM DRS cluster group in the "MyCluster" cluster by adding a list of virtual machines inside.
New-DrsClusterGroup -Name "MyDrsClusterGroup" -VM "MyVM1", "MyVM2" -Cluster "MyCluster"
You can UPDATE objects by using Invoke-DrsRecommendation cmdlet. See example below: 
# Retrieves and applies DRS recommendations with priorities 1 and 2.
Get-DrsRecommendation -Priority 1,2 | Invoke-DrsRecommendation
You can REMOVE objects by using Remove-DrsClusterGroup cmdlet. See example below: 
# Removes the "MyClusterGroup" DRS cluster group from the environment.
Remove-DrsClusterGroup -DrsClusterGroup "MyClusterGroup"
