Here is what I am trying, but it doesn't seem to adhere to any limit...it just fires a bunch of vmotions off until i manually kill the script:
Connect-VIServer vcenter
function Wait-mTaskvMotions {
[CmdletBinding()]
Param(
[int] $vMotionLimit=1,
[int] $DelayMinutes=5
)
$NumvMotionTasks = (Get-Task | ? { ($_.PercentComplete -ne 100) -and ($_.Description -match 'Apply Storage DRS recommendations|Migrate virtual machine')} | Measure-Object).Count
While ( $NumvMotionTasks -ge $vMotionLimit ) {
Write-Verbose "$(Get-Date)- Waiting $($DelayMinutes) minute(s) before checking again."
Start-Sleep ($DelayMinutes * 60)
$NumvMotionTasks = (Get-Task | ? { ($_.PercentComplete -ne 100) -and ($_.Description -match 'Apply Storage DRS recommendations|Migrate virtual machine')} | Measure-Object).Count
}
Write-Verbose "$(Get-Date)- Proceeding."
} # end function
$filepath = "C:\powershellscripts\MigrationVMs.csv"
$csvobj = import-csv $filepath
foreach ($row in $csvobj) {
$vmobj = get-vm $row.vmname
$ds = get-datastore $row.destds
$vmobj | move-vm -datastore $ds -confirm:$false -runasync
Wait-mTaskvMotions -vMotionLimit 4 # This will keep going through the foreach loop until 4 tasks are registered (vMotion or Storage vMotion), waits 5 minutes between checks. Will only continue to process loop when vMotion tasks are less than 4.
}
