Conclua as etapas a seguir para hosts ESXi.

Passos

Determine o ESXi e a máquina virtual usando o VMware vSphere Client.
Determine os LUNs SAN a serem migrados usando o vSphere Client.

Determine os volumes VMFS e RDM (vfat) a serem migrados: esxcli storage filesystem list

No caso de VMFS com extends (VMFS expandido), todos os LUNs que fazem parte do span devem ser migrados. Para mostrar todas as extensões na GUI, vá para Configuração e armazenamento de dados e clique em datastore para selecionar o link Propriedades.

Após a migração, ao adicioná-los de volta ao armazenamento, você verá várias entradas de LUN com o mesmo rótulo VMFS. Neste cenário, deve pedir ao cliente que selecione apenas a entrada marcada como Head.

Determine o LUN e o tamanho a serem migrados: esxcfg-scsidevs -c

Identificar LUNs de mapeamento de dispositivos brutos (RDM) a serem migrados.

Encontrar dispositivos RDM: find /vmfs/volumes -name **-rdm**

A passagem é RDM com o físico (RDMP), e o nonpassthrough é RDM com o virtual (RDMV). As VMs com RDMs virtuais e cópias Snapshot da VM serão interrompidas após a migração devido ao VM Snapshot delta vmdk apontando para um RDM que tenha um ID naa obsoleto. Portanto, antes da migração, peça ao cliente para remover todas as cópias Snapshot de tais VMs. Clique com o botão direito do rato em VM e clique no botão Snapshot -→ Snapshot Manager Delete All (Eliminar tudo). Consulte o NetApp KB 3013935 para obter detalhes sobre o bloqueio acelerado por hardware para VMware no armazenamento NetApp.

Identificar o mapeamento de dispositivos LUN naa para RDM.
