On Cisco UCS C-Series M6 servers running CIMC 4.3.5 or later, enabling VMD in BIOS with multiple NVME drives can cause storage subsystem initialization to exceed 15 minutes, leading to Intersight Server Profile deployment failures. Disabling VMD or reducing the number of drives can resolve the issue. Earlier firmware versions may not be affected. |

On Microchip-based storage cards, the Virtual Drive (VD) shows as "Inoperable" even when all disks are online because the firmware automatically changes drive assignments to optimize performance, ignoring user settings from management tools. |
Use arcconf output to check drive assignments in spans. Firmware may override management tool settings for better performance. |
