It is possible because of bad design from the SSD manufacturer, the EUI64 are all the same for the 4 NVMe SSD, under this case, the ESXI will only recognized one of the 4 disks (since the disk will be t10.xxx_EUI64, and EUI64 are the same for all 4 NVMe SSD, The "storage" "adapters" tab did show there are 4 interfaces (adapters), but the "stroage" "devices" will only show 1 disks. The NVMe SSD from the same company may use the same EUI64 for every NVMe SSD on the same interface (say using an ASUS Hyper M.2 X16 PCIe 3.0x4 Expansion card with 4 identical NVMe SSD). xxx_controller_serial_number as alternative primary IDġ. Being a software engineer, I am disturbing by the way this software create the disk ID.Īccording to the following table from VMware Docs we have some case that the software will not recognize the disk or lost disks.
