Add multiple datastores to multiple vSphere hosts

#
#  Add Datastores to all hosts in all clusters in a specified datacenter
#  If a host isn't in a cluster it won't get the datastore
#  Easy enough to change to do all hosts in a datacenter, all in vCenter etc
#
#  Change the value below to point it to your own vCenter
$myvCenter = "vcenter.example.com"
 
# Array of arrays below holds NFS-hostname, NFS-path and Datastore name, should be easy to add to
$nfsArray = @(
			  @("nfsserver1","/vol/nfspath1","VMstore1"),
			  @("nfsserver2","/vol/nfspath2","VMstore2"),
			  @("nfsserver3","/vol/nfspath3","VMstore3")
			 )
 
$datacenter = Read-Host -Prompt "Datacenter name"
 
Write-Host "Datacenter is $datacenter"
 
connect-viserver -server $myvCenter
 
#
# Get all hosts in all clusters in the named datacenter
$ObjAllHosts = get-datacenter -name $datacenter | Get-Cluster  |  Get-VMHost 
 
ForEach($objHost in $ObjAllHosts){
	ForEach($nfsItem in $nfsArray) {
 
      Write-Host "Adding datastore" $nfsItem[2] "with path" $nfsItem[0]":"$nfsItem[1] "to" $objHost
      New-Datastore -Nfs -NfsHost $nfsItem[0] -Path $nfsItem[1] -Name $nfsItem[2] -VMHost (Get-VMHost $objHost)
    }
