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。

當主機小於可用的 StartOptimizationLevel 指定數量時，動態優化會嘗試重新平衡負載。

因為另一個節點正在關閉，因此電源優化永遠不會強制主機擁有小於指定數量，PlacementLevel 可用。

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 $HostGroup 之主機群組的主機保留對象，然後將物件儲存在$HostReserve變數中。

最後一個命令會使用管線運算符，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。
