У меня есть сервер Scientific Linux 6.5 с RAID с дисками SSD. Я вижу несколько ошибок в файле dmesg, но утилит RAID-контроллера (контроллера LSI) нет предупреждений или ошибок.
Сервер представляет собой Supermico D20-4x-M4, подключенный напрямую через Infiniband к серверу хранения с SSD RAID. Контроллер - LSI MegaRaid SAS 9286CV-8e. И диск стоит SAMSUNG MZ7WD120.
Ошибки файлов dmesg следующие:

Также я пробовал:
smartctl /dev/sdb -a -T permissive
со следующим результатом:
