Start-HVPool -Recompose Failure

[cshrookie]

Hello, guys.

As a newbie to powercli and api, I am struggling to write this simple script for automating regular scheduled snapshot and corresponding recomposing the linked clone pool based on the image.

After hours of searching, I landed on hv.helper module and managed to work on the simple script.

However, I faced the seemingly last but not the least obstacle.

I face the below error message which seems related to the module of hv.helper judging from it saying that I am having some parameter exception and missing.

Anyone could help me? Any help would be appreciated.

My Script

`Connect-VIServer -Server -User -Password

###############

#Day values for snapshot name $Today = (Get-Date).ToString(“yyyy-MM-d”) $Yesterday = (Get-Date).AddDays(-1).ToString(“yyyy-MM-d”)

###############

$vm = Get-VM -Name $vmName

#Create snapshot for today New-Snapshot -VM '1809_templete' -Name $Today -Description "$Today daily snapshot"

#Delete snapshot from the previous day Get-Snapshot -VM $vm | Where-Object {$_.name -contains $Yesterday} | Remove-Snapshot -Confirm:$false

Import-Module VMware.VimAutomation.HorizonView

Import-Module VMware.Hv.Helper

Connect-HVServer -Server -User -Password

Start-HVPool -Pool 'link01' -Recompose -LogoffSetting FORCE_LOGOFF -ParentVM '1809_templete' -SnapshotVM '$Today' -StopOnFirstError $false`

The resulting error message
