I recently ran into the following problem: the situation occurs when you want to deploy a virtual machines with PowerCLI to a cluster with multiple datastores but your not licensed for Storage DRS.
The default PowerCLI behavior is to select the first datastore detected (alphabetic order). To solve this problem I created the following PowerCLI code:
### Variables $CLUSTER = "Production" # Cluster name $FOLDER = "Deployed VMs" # Virtual Machine folder ### Select datastores available and sort them on free space (select the one with most space free) $DS = Get-Cluster -Name $CLUSTER | Get-Datastore | Select Name, FreeSpaceGB | Sort-Object FreeSpaceGB -Descending | Select -first 1 ### Create a virtual machine called VM01 New-VM -Name VM01 -ResourcePool $CLUSTER -Datastore $DS.Name -Location $FOLDER -MemoryGB 1 -CD -DiskGB 5
The code is tested with PowerCLI 6.5 R1 against a VMware vCenter 6.0 server.
