I need to create to Redundant VMs (both on 2 different datastores) via function - vmware

Question

I have defined all the needed variables in a separate Variable_Defination.ps1 file and have called it up here.
Is there a better way to do this?
I just want a script to create 2 redundant VMs both running on separate datastores and having Affinity rule set up for disaster recovery cases
. ./Variable_Defination.ps1
function CreateRedundantVMs {
Param(
[Parameter(Mandatory=$true, ValueFromPipeline=$true)]
[string]$ClusterName,
[string]$ComputerName1,
[string]$ComputerName2,
[string]$sourcetemplate,
[string]$InfraResourcePoolName,
[string]$OSCustomizationspec,
[string]$description
)
$Viabledatastores = (Get-Cluster $ClusterName | Get-Datastore) |
Where {$_.Name -like '*vSSD*'} |
Sort-Object FreeSpaceGB -Descending |
Select -First 2 -ErrorAction 'Stop'
if ($Viabledatastores) {
$Viabledatastores
} else {
Write-Host "No Viable Datastores found"
break;
}
Write-Verbose "`n---------------------- Creating redundant VMs now ------------------------`n " -Verbose
