H710 Impossible d'ajouter un disque neuf au raid 5

Bonjour,

Nous avons commandé un disque de remplacement pour le raid 5 dégradé de notre serveur.
Initialement constitué de disques SATA 2 To qui ne sont plus dispo :
1.818 TB SATA HDD N N 512B ST2000NM0033-9ZM175

Avec le service tag, DELL (via notre fournisseur) nous a conseillé des disques 4 To SAS :
3.637 TB SAS HDD N N 512B ST4000NM0295    (cette ref a été récupérée via perccli une fois le disque installé)

A réception des disques, j'installe un disque à la place du défectueux et tente l'installation avec percli :

Pouvez vous m'indiquer pourquoi le contrôleur refuse le disque ?

Pouvez vous vérifier la compatibilité d'un disque SAS dans une grappe raid de disques SATA ?

Merci
