Issues having a retry count work in powershell - azure

Question

I have a Powershell script that checks on a set of VM status before starting them. If the VM'S are in deallocating mode there should be a sleep and retry on 30 seconds. The code does not do a a retry. The code does a vm start in batches on 2 for vm's with wilcards as mentioned below in an order.
Need help if possible
$ResName= "resvmtest"
$action="start"
if($action -eq "start"){
$vnames=#('*dom*','*DBs*','*')
foreach($vname in $vnames) {
Write-Host "Starting VM with "$vname
$vmList = Get-AzVM -ResourceGroupName $ResName -Name $vname -Status | Select-Object Name, PowerState, ResourceGroupName
do{
$batch = #{
Skip = 0
First = 2
}
do{
foreach($vm in ($vmList | Select-Object #batch)){
$Stoploop = $false
[int]$Retrycount = "0"
do {
try {
if($vm.PowerState -eq "VM Deallocated"){
Write-Host "Job completed"
$Stoploop = $true
}
}
catch {
if ($vm.PowerState -eq "VM Deallocatting") {
Write-Host "VM Still not Deallocated"
Start-Sleep -Seconds 10
$Retrycount = $Retrycount + 1
}
}
}
While ($Stoploop -eq $false)
$params = #($vm.Name, $vm.ResourceGroupName,$vm.PowerState)
$job = Start-Job -ScriptBlock {
param($ComputerName,$serviceName,$statuses)
Start-AzVM -Name $ComputerName -ResourceGroupName $serviceName
} -ArgumentList $params
}
Wait-Job -Job $job
Get-Job | Receive-Job
$batch.Skip += 2
}
until($batch.skip -ge $vmList.count)
}
while($job.state -ne "Completed")
}
}

If you just want to wait for a VM's PowerState turns to VM Deallocated from VM Deallocatting, try the code below:
$vms = Get-AzVm -Status| Select-Object Name, PowerState,ResourceGroupName
#pick certain vm for demo here.
$vm = $vms[1]
$retryCount = 0
while($vm.PowerState -eq 'VM deallocating'){
Write-Host "waiting for VM deallocated..."
Start-Sleep -Seconds 5
$retryCount +=1
Write-Host "check count:$retryCount"
#get latest vm status
$vm.PowerState = (Get-AzVM -Name $vm.Name -ResourceGroupName $vm.ResourceGroupName -Status).Statuses[1].DisplayStatus
Write-Host "vm current state:"$vm.PowerState
}
Write-Host "vm new state:" + $vm.PowerState
Result:
