Problem Description
The NIC is not displayed on the HDM after nvme raid is configured
Process Analysis
Because VROC is used to configure NVME arrays, the VMD function must be enabled for each NVME slot. The VMD is enabled in all slots, including the NIC. As a result, the NIC cannot be used properly
Solution
Enable the VMD function only for the slot whose number is more than 100 for VROC RAID configuration of NVME.
Disable the VMD function of the other pcie slots.
