On a Dell R630 server, I did had a Raid 1 virtual disk on a H330 Raid controller (Mini) controller having already 2 Raid 1 virtual disks. On ESXi 6.5 U1, I can see the two first Disks and a datastore has been defined on each without any problem. I want to add a datastore on the third virtual disk but even after rescan the third virtual disk is not detected. What did I forgot ?
