Fair warning, I don't deal much with Dell, but it's curious that iDrac
lists the device protocol as MI

MI or the Management Interface is defined by NVMe, but it isn't the
same as a block interface. MI typically uses SMBUS and not PCIe to
communicate with the device. So it's possible that the device is
visible to iDrac via SMBUS but may not be on the PCIe bus for
$reasons. Does iDrac have any tools to interact with the device via
MI?
