export resource pools from one cluster to another

[cer113a]

HI

I have 2 clusters one cluster is with old hosts and we just provisioned new hosts but need to copy all resource pools from one cluster to another in the same datacentre

Exporting is easy

#Export Resource Pool Structure
#By https://communities.vmware.com/message/2344027
Connect-VIServer -Server king-vcenter-01.scc-zip.net -Protocol https -User [e-mail] -Password rikoLA!123
$clusterName = "Mtl1-G8"
$cluster = Get-Cluster -Name $clusterName
Get-ResourcePool -Location $cluster |
Select Name,@{N="Parent";E={
  $path = $_.Parent.Name,$_.Name -join '/'
  $parent = $_.Parent
  while($parent -isnot [VMware.VimAutomation.ViCore.Impl.V1.Inventory.ClusterIMpl]){
    $path = $parent.Parent.Name,$path -join '/'
    $parent = $parent.Parent
  }
  $path}} |
Export-Csv -path C:\vspherescripts\scriptsoutput\montrealpools.csv -NoTypeInformation -UseCulture

But I cannot import these resource pools into another cluster with the same values it says that cluster doesnt exist although it is created in vcenter under same datacentre

How would i import. Export gives me nice csv file but cannot import

Without seeing the code you use to import it is hard to tell what could go wrong.

PS: not sure you want to publish the credentials for your vCenter on here

HI I was playing with it a bit and came up with this

#Export Resource Pool Structure
#By https://communities.
$clusterName = "clusterA"
$cluster = Get-Cluster -Name $clusterName
Get-ResourcePool -Location $cluster |
Select Name,@{N="Parent";E={
  $path = $_.Parent.Name,$_.Name -join '/'
  $parent = $_.Parent
  while($parent -isnot [VMware.VimAutomation.ViCore.Impl.V1.Inventory.ClusterIMpl]){
    $path = $parent.Parent.Name,$path -join '/'
    $parent = $parent.Parent
  }
  $path}} |
Export-Csv -path C:\storagemigrate\montrealpools.csv -NoTypeInformation -UseCulture

Couldnt figure out how to do it automatically so did little bit of manual work and then import function

I went to csv file and put new cluster name for example clusterB

then execute this

foreach($row in (Import-Csv C:\storagemigrate\montrealpools.csv -UseCulture)){
  $clusterName,$pools = $row.Parent.Split('/')
  Try {
    $skip = $false
    $location = Get-Cluster -Name $clusterName -ErrorAction Stop
  }
  Catch {
    "Cluster $clusterName not found"
    $skip = $true
  }
  if(!$skip){
    foreach($rp in $pools){
      Try {
        $location = Get-ResourcePool -Name $rp -Location $location -ErrorAction Stop
      }
      Catch {
        $location = New-ResourcePool -Name $rp -Location $location
      }
    }
  }
}

This actually copies all resource pools with the same name. I hoped it will keep resource pools settings but it didnt however good thing is that only one or 2 resporce pools have changed settings so that will work out even if i have to change them manually
