Get-DrsRule Command | Vmware PowerCLI Reference

Get-DrsRule

This cmdlet retrieves the list of DRS rules for the specified clusters. Each rule defines the virtual machines that can run on the same host (affinity rule) or must run on different hosts (anti-affinity).Note: To retrieve VMHostAffinity rules, you need to state this explicitly by using the Type or the VMHost parameter. Otherwise, this cmdlet returns VMAffinity and VMAntiAffinity rules.

Syntax

Get-DrsRule

[ [-VM ] < VirtualMachine[] > ]
[-Name < String[] > ]
[-Server < VIServer[] > ]
[-Type < ResourceSchedulingRuleType[] > ]
[CommonParameters]

Parameters

Required Parameter Name Type Position Features Description
required
 Cluster Cluster[] 1
  • pipeline
  • wildcards
 Specifies the clusters for which you want to retrieve the DRS rules.
optional VM VirtualMachine[] 2
  • pipeline
  • wildcards
 Specifies virtual machines to filter the DRS rules that reference them. Passing values to this parameter through a pipeline is deprecated and will be removed in a future release.
optional Name String[] named
  • wildcards
 Specifies the name of the DRS rule you want to retrieve.
optional Server VIServer[] named
  • wildcards
 Specifies the vCenter Server systems on which you want to run the cmdlet. If no value is provided or $null value is passed to this parameter, the command runs on the default servers. For more information about default servers, see the description of Connect-VIServer.
optional Type ResourceSchedulingRuleType[] named
Specifies the type of DRS rules you want to retrieve. This parameter accepts VMAntiAffinity, VMAffinity, and VMHostAffinity values. You cannot set this parameter, when the VMHost parameter is specified.

optional VMHost VMHost[] named
  • pipeline
 Specifies VM hosts to filter the DRS rules that reference them. When this parameter is specified, the cmdlet returns only VMHostAffinity rules. You cannot set this parameter, when the Type parameter is specified.

Examples

Example 1 

$myCluster = Get-Cluster -Name "MyCluster1"
Get-DrsRule -Cluster $myCluster -Name "*Rule1*"

Retrieves the DRS rules for the cluster stored in the $myCluster variable, whose names contain "Rule1".

Example 2 

Get-Cluster -Name 'MyCluster1' | Get-DrsRule

Retrieves the virtual machine affinity and anti-affinity rules for the specified cluster by pipeline.

Example 3 

$myVm1 = Get-VM -Name 'MyVm1'
$myCluster1 = Get-Cluster 'MyCluster1'
Get-DrsRule -Cluster $myCluster1 -VM $myVm1

Retrieves the virtual machine affinity and anti-affinity rules for the specified virtual machine in the specified cluster.

Example 4 

Get-Cluster 'MyCluster1' | Get-DrsRule -Type VMHostAffinity

Retrieves virtual machine to host affinity rules for the specified cluster by pipeline.

Example 5 

$myVMHost1 = Get-VMHost -Name 'MyVMHost1'
$myCluster1 = Get-Cluster -Name 'MyCluster1'
Get-DrsRule -Cluster $myCluster1 -VMHost $myVMHost1

Retrieves virtual machine to host affinity rules for the specified host and cluster.
