I only learn day by day what a mess all that is ...

No, I don't think so. But maybe you'r right. No sdd in fstab or in the
mounts at all and ...

these 2 look similar to me:

So we have 0x600c0ff0001e91b2c1bae25601000000 twice, right?
There's a /dev/sdb as well, commented in fstab with "9750-8i Raid6
(4x3TB + 2x4TB)" but that seems another "branch" of devices:
# /usr/bin/sg_vpd --page=di /dev/sdb
