Do You Like Automation? (VMware Only)

Recently I was reviewing my environment and found that many of my VMs are not in any DRS rule. So I was looking an easy way to find missing VMs. Unfortunately I could not find any easy way to accomplish this task but I found an interesting powercli module which could ease my work a bit (Thanks to LUCD Notes)

What you need is to import DRSRule module to your vSphere Powercli. Its pretty easy

1.Download DRSRule modules from github

2.Unzip the folder

3.Copy unzipped DRSRule module folder to your modules directory

4.Import the module using Ïmport-Module .\DRSRule

Once it is imported, you can use many magics with these modules.DRSRule module contains the following cmdlets

    New-DrsVMGroup                  Create a DRS VM group
    New-DrsVMHostGroup              Create a DRS VMHost group
    New-DrsVMToVMHostRule           Create a DRS VM to VMHost rule
    New-DrsVMToVMRule               Create a DRS VM to VM rule
    Get-DrsVMGroup                  Retrieve DRS VM groups
    Get-DrsVMHostGroup              Retrieve DRS VMHost groups
    Get-DrsVMToVMHostRule           Retrieve DRS VM to VMHost rules
    Get-DrsVMToVMRule               Retrieve DRS VM to VM rules
    Set-DrsVMGroup                  Change a DRS VM group
    Set-DrsVMHostGroup              Change a DRS VMHost group
    Set-DrsVMToVMHostRule           Change a DRS VM to VMHost rule
    Set-DrsVMToVMRule               Change a DRS VM to VM rule
    Remove-DrsVMGroup               Remove a DRS VM group
    Remove-DrsVMHostGroup           Remove a DRS VMHost group
    Remove-DrsVMToVMHostRule        Remove a DRS VM to VMHost rule
    Remove-DrsVMToVMRule            Remove a DRS VM to VM rule
    Export-DrsRule                  Save all DRS groups and rules to a JSON file
    Import-DrsRule                  Import DRS groups and rules from a JSON file

If you can make a one liner to list VMs which are part of a DRS rule write me please. Have fun

Update :Thanks to my friend Grzegorz, he send me a one-liner to find missing VMs

(get-cluster cluster_name).ExtensionData.ConfigurationEx.group|?{$_.vm}|%{” GROUP $($_.name) found in this cluster”; foreach($currentvm in $_.vm) { (get-view -id $currentvm).name } }

I am going to use following command now.

Get-DrsVMGroup -Name ‘DRSrule_VMS‘-cluster Dev | Set-DrsVMGroup -VM testvm -Append

The above command will append vm called testvm to Dev cluster DRSrule called DRSrule_VMs

Thanks for reading the post… Have a good dayDisclaimer: I have 0 scripting knowledge
