[<CommonParameters>] Description
Set-SCHostReserve Cmdlet 會修改主機群組的主機保留設定。 若要修改主機群組的主機保留設定，該主機群組不得從父主機群組繼承其設定。
當您設定主機保留層級時，單位參數，例如 GB 或 Percentage，會指定其他層級的單位，例如 StartOptimizationLevel 和 PlacementLevel。
VMHostReserveLevel、StartOptimizationLevel和PlacementLevel的值必須依序表示。 例如， StartOptimizationLevel 的值不能小於 VMHostReserveLevel的值， 而 PlacementLevel 的值不能小於 StartOptimizationLevel的值。
當主機的 StartOptimizationLevel 數量小於指定的可用數量時，動態優化會嘗試重新平衡負載。
由於另一個節點已關閉電源，因此 Power Optimization 永遠不會強制主機小於 PlacementLevel 可用的指定數量。
範例
範例 1：修改指定主機群組的 CPU 主機保留和放置設定
PS C:\> $HostGroup = Get-SCVMHostGroup "HostGroup01"
PS C:\> $HostReserve = Get-SCHostReserve -VMHostGroup $HostGroup
PS C:\> $HostReserve | Set-SCHostReserve -CPU -PlacementLevel 75 -StartOptimizationLevel 80 -VMHostReserveLevel 90第一個命令會取得名為 HostGroup01 的主機群組物件，並將物件儲存在$HostGroup變數中。
第二個命令會取得儲存在 $HostGroup 之主機群組的主機保留物件，然後將物件儲存在$HostReserve變數中。
最後一個命令會使用管線運算子，將儲存在 $HostReserve中的主機保留傳遞至 Set-SCHostReserve Cmdlet，以更新主機保留和放置設定。
