Vérifier l’état de vos disques connectés à une carte 3Ware sous Linux

3ware

Ayant plusieurs cartes raid de la marque 3Ware, il est important pour moi de pouvoir contrôler l'état SMART de mes disques durs à tout moment.

Pour cela, il suffit d'installer le paquet "smartmontools" via la commande:

apt-get install smartmontools

Smartmontools est un paquet qui permet de récupérer des informations SMART sur vos disques sur les systèmes Linux.

Les commandes suivantes ont été testées sur les 2 cartes raid 3Ware suivantes:

  • Carte Raid 3ware 8506 8 Ports Sata
  • Carte Raid 3Ware AMCC 12 Ports SATA II Raid Controller 9550SXU-12

Voici la commande à utiliser pour récupérer les informations SMART de vos disques durs connectés à votre carte contrôleur raid 3Ware:

smartctl -a -d 3ware,N /dev/tweY
smartctl -a -d 3ware,N /dev/twaY

Le N correspond au port de la carte 3Ware sur lequel votre disque est connecté (les valeurs sont comprises entre 0 et 31).

Il est également possible d'utiliser l'outil "tw_cli" fourni par 3Ware pour connaitre les ports sur lesquels sont connectés vos disques durs.

tw_cli info

Ce qui vous retournera:

Pour obtenir les informations concernant le contrôleur c0:

tw_cli info c0

Ce qui retournera quelquechose de la sorte:

p1    OK             u0   233.81 GB SATA  1   -            WDC WD2503ABYX-01WE

Enfin pour obtenir les informations SMART d'un disque précis, il faut utiliser la commande suivante:

smartctl -a -d 3ware,0 /dev/twa0
