[BUG] `--scan-open` might not find all revelant disks

[PhilipMay]

see here

root@wobdevl011:~# lsblk
NAME        MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
sda           8:0    0 10.9T  0 disk

root@wobdevl011:~# smartctl --scan-open
/dev/sda -d sat # /dev/sda [SAT], ATA device

but also see here (same machine):

root@wobdevl011:~# smartctl --scan-open -d nvme
/dev/nvme0 -d nvme # /dev/nvme0, NVMe device

interesting doc here: https://www.smartmontools.org/browser/trunk/smartmontools/smartd.8.in

Examine all entries "/dev/hd[a-t]" for IDE/ATA devices, and "/dev/sd[a-z]", "/dev/sd[a-z][a-z]" for ATA/SATA or SCSI/SAS devices. Disks behind RAID controllers are not included.

If directive '-d nvme' or no '-d' directive is specified, examine all entries "/dev/nvme[0-99]" for NVMe devices.

Could also be because of old smartctl version!
