Description

O cmdlet Set-SCHostReserve modifica as configurações de reserva do host para um grupo de host. Para modificar as configurações de reserva do host para um grupo de host, esse grupo de hosts não deve herdar suas configurações de um grupo de host pai.

Quando você define os níveis de reserva do host, os parâmetros de unidade, como GB ou Porcentagem, ditam as unidades nas quais os outros níveis, como StartOptimizationLevel e PlacementLevel, são expressos.

Os valores de VMHostReserveLevel, StartOptimizationLevel e PlacementLevel devem ser representados em ordem. Por exemplo, o valor de StartOptimizationLevel não pode ser menor que o valor de VMHostReserveLevel e o valor de PlacementLevel não pode ser menor que o valor de StartOptimizationLevel.

Quando o host tem menos do que o valor especificado para StartOptimizationLevel disponível, a Otimização Dinâmica tenta reequilibrar a carga.

Um host nunca será forçado pela Otimização de Energia a ter menos do que o valor especificado para PlacementLevel disponível devido a outro nó ser desligado.

Exemplos

Exemplo 1: modificar as configurações de reserva e posicionamento do host da CPU para um grupo de host especificado

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

O primeiro comando obtém o objeto de grupo de host chamado HostGroup01 e armazena o objeto na variável $HostGroup.

O segundo comando obtém o objeto de reserva de host para o grupo de host armazenado em $HostGroup e armazena o objeto na variável $HostReserve.

O último comando usa o operador de pipeline para passar a reserva de host armazenada em $HostReserve para o cmdlet Set-SCHostReserve , que atualiza as configurações de reserva e posicionamento do host.
