A customer is trying to enable NVMe and wants to use the FC adapters in...

The problem is that there are no FC adapters with a max-speed of 32 Gbps. NVMe/FC support depends on platform, adapter, and speed capability. The exhibit shows FC adapters, but their max-speed is 16 Gbps, which does not satisfy the requirement being tested. The issue is not that the physical protocol is already set to NVMe; FC adapters are configured and then used for FC or FC-NVMe services according to supported capabilities. Media type is not NVMe, because NVMe is a storage protocol, not an optical media type. The wording 'cannot enable the protocol' requires checking whether installed adapters meet the hardware support requirements. A support engineer should verify adapter model, max speed, port mode, firmware, and ONTAP support matrix before attempting to configure NVMe. In this exhibit, the absence of 32 Gb-capable FC adapters is the blocking condition.
