errado # de dispositivos em RAID definidos no Centos 6.7

Question

Acabei de configurar um dos nossos servidores com o Centos 6.7. É uma máquina que não está em uso há pelo menos um ano. Eu tive que configurá-lo um par de vezes, mas cada vez que um dos problemas estava com o RAID de armazenamento na máquina. É configurado como RAID10, mas o Centos parece ter algum problema com isso.

Tenho pouca experiência em lidar com RAIDS em sistemas Linux e estou completamente preso.

Aqui está a saída de / var / log / messages que acredito serem as partes relevantes.

Eu posso executar qualquer comando que você precisar para obter mais informações.

Alguém aqui capaz / disposto a ajudar?

EDIT: É um HP ProLiant ML150 G3 e aqui é um link para o log completo.

Ele tem 6 discos rígidos, os dois discos de 500 GB são configurados como RAID 1 para o sistema operacional.

EDIT 2: saída do dmesg

EDIT 3: Eu tentei apagar o RAID completamente e depois recriá-lo sem nenhum resultado. A mesma coisa acontece.
