The DRSRule module allows you to work with all types of vSphere DRS rules. The module provides support for VM and VMHost groups. And, it works with affinity/anti-affinity VM rules and VM to VMHost rules.

The module came from the need for DRS rule/group info gathering, exporting, and recreating. Initially there were some code blocks for exporting rule info and for importing again those rules, but things evolved into a module.

A couple of examples:

• Export rule/group info: Export-DrsRule -Path c:\someFolder\myDrsRuleAndGroupInfo.json
• Import rule/group info: Import-DrsRule -Path c:\someFolder\myDrsRuleAndGroupInfo.json

• Download and extract the module .zip file
• Unblock-File on the extracted contents
• Import-Module <path\To\ModuleFolder>
• Use Get-Help as per usual for cmdlet help and examples

• Export/Import:
  • Export-DrsRule
  • Import-DrsRule
• Get:
  • Get-DrsVMGroup
  • Get-DrsVMHostGroup
