[<CommonParameters>] 说明
Set-SCHostReserve cmdlet 修改主机组的主机保留设置。 若要修改主机组的主机保留设置，该主机组不得从父主机组继承其设置。
设置主机保留级别时，单元参数（如 GB 或 百分比）指示表示其他级别（如 StartOptimizationLevel 和 PlacementLevel）的单位。
VMHostReserveLevel、StartOptimizationLevel 和 PlacementLevel 的值必须按顺序表示。 例如， StartOptimizationLevel 的值不能小于 VMHostReserveLevel 的值， PlacementLevel 的值不能小于 StartOptimizationLevel 的值。
当主机小于可用 StartOptimizationLevel 的指定量时，动态优化会尝试重新平衡负载。
由于另一个节点被关闭，电源优化永远不会强制主机的可用量小于 PlacementLevel 的指定数量。
示例
示例 1：修改指定主机组的 CPU 主机保留和放置设置
PS C:\> $HostGroup = Get-SCVMHostGroup "HostGroup01"
PS C:\> $HostReserve = Get-SCHostReserve -VMHostGroup $HostGroup
PS C:\> $HostReserve | Set-SCHostReserve -CPU -PlacementLevel 75 -StartOptimizationLevel 80 -VMHostReserveLevel 90第一个命令获取名为 HostGroup01 的主机组对象，并将对象存储在$HostGroup变量中。
第二个命令获取存储在$HostGroup中的主机组的主机保留对象，然后将该对象存储在$HostReserve变量中。
最后一个命令使用管道运算符将存储在 $HostReserve 中的主机保留传递给 Set-SCHostReserve cmdlet，该 cmdlet 更新主机保留和放置设置。
