Anexar discos Passthough via WMI (IDE ou SCSI)

Se deseja usar discos passthough com Hyper-V como vou anexar os discos? Que scripts utilizar? Bem, aqui está a resposta… Mas primeiro precisa decidir se vai para utilizar a controladora IDE virtual ou a controlador SCSI virtual. A controladora IDE é ideal se planear a inicialização a partir do disco de passthough ou se seu guest não suporta o adaptador SCSI virtual (Ex: Linux). O controlador SCSI é ideal se quiser adicionar/remover armazenamento da máquina virtual enquanto esta a ser executada (recurso do Hyper-V R2) ou se tiver mais de 4 discos que deseja adicionar. Anexar ao IDE ou SCSI é bastante semelhante – existe realmente apenas 1, diferença em negrito nos dois scripts abaixo, só tem que seleccionar a controladora correcta. Excepto se for usar o número do disco físico para Gestor de disco (não muito mau) ou se fornecer um ID de LUN quando criar o armazenamento (no caso de uma SAN), pode usar o que pode ser um pouco mais determinista.
