An administrator plans to deploy a workload domain with VMware Virtual Machine File System on Fibre Channel (VMFS-FC) as principal storage. What must be completed before the hosts can be commissioned?
A.
Configure two 10 Gbps NICs for the storage network.
B.
Mount the VMFS datastore(s) on all the hosts.
C.
Enable pass-through mode on the storage controller.
For hosts that will be commissioned for a workload domain using VMFS on Fibre Channel as principal storage, the Fibre Channel storage must already be accessible to every ESX host before commissioning begins. VMware Cloud Foundation 9.0 explicitly states: “The VMFS datastore must be mounted on all the hosts before commissioning.”
VCF also requires supported Fibre Channel HBAs and drivers, and the hosts must be able to access the FC array. Fibre Channel does not require a dedicated Ethernet storage network because FC traffic uses Fibre Channel HBAs and the SAN fabric rather than VMkernel-based IP storage networking.
A network pool must exist before host commissioning, but for VMFS-FC it is used for VCF host networking such as management and vMotion; it is not a dedicated Fibre Channel storage network. Therefore, option D is not the specific storage prerequisite asked here. Pass-through mode is also unrelated to FC principal storage.
