Description

Hi,

I am trying to use smartctl 7.2 2020-04-23 to interrogate my Samsung 970 Pro NVMe PCIe M.2 drives and I am having no luck.

I compiled the executable on an Ubuntu machine, but I am running it on a VMware vSphere ESXi 6.7 host server.

I have two 970 Pro devices installed:

I seem to be able to open the NVMe device successfully:

[root@mc-esxi-p-101:/opt/smartmontools] ./smartctl --device=nvme /dev/disks/t10.NVMe____Samsung_SSD_970_PRO_1TB_________________40FAB2915A382500

NVMe device successfully opened

Use 'smartctl -a' (or '-x') to print SMART (and more) information

[root@mc-esxi-p-101:/opt/smartmontools]

But when I try to show any information about the drive with -x or -a I get the same error:

[root@mc-esxi-p-101:/opt/smartmontools] ./smartctl -a --device=nvme /dev/disks/t10.NVMe____Samsung_SSD_970_PRO_1TB_________________40FAB2915A382500

Read NVMe Identify Controller failed: NVME_IOCTL_ADMIN_CMD: Function not implemented
[root@mc-esxi-p-101:/opt/smartmontools]

I know the 970 Pros support SMART reporting, as I was able to interrogate them in the same machine/hardware configuration when it was previously running a Windows 10 OS, admittedly I was using Crystal Disk Info.

Is there anything I can do to get this working or is the NVMe support for SMART reporting in smartctl just not available yet?

Any help will be greatly appreciated.

Many Thanks
Martin

Apparently the ESXi kernel does not implement this NVMe pass-through I/O-control. It is available on regular Linux kernels.

If possible, please ask VMware support if an alternative I/O-control exists. Leaving ticket open as undecided for now.

NVME_IOCTL_ADMIN_CMD is not implemented on ESXi and there is no known alternative.

Feel free to reopen this ticket if information about an alternative pass-through I/O-control is available.
