Невозможно получить показатели SMART с Seagate Disks в ОС Debian

Ссылаясь на вопрос Вот, Я тоже пытаюсь получить все атрибуты, как описано в этом блоге Вот.

Я использую Debian 6 в качестве ОС и установил smartmontools версии 6.3 с помощью apt-get. Мои 6 дисков находятся в режиме RAID. Сначала я включил статистику с помощью команды

sudo smartctl -s on -o on -S on -d megaraid,0 /dev/sda
sudo smartctl -s on -o on -S on -d megaraid,1 /dev/sda
sudo smartctl -s on -o on -S on -d megaraid,2 /dev/sda
sudo smartctl -s on -o on -S on -d megaraid,3 /dev/sda
sudo smartctl -s on -o on -S on -d megaraid,4 /dev/sda
sudo smartctl -s on -o on -S on -d megaraid,5 /dev/sda

После этого я использую следующую команду, чтобы получить все атрибуты:

smartctl -a -i -d megaraid,0 /dev/sda

но я не вижу никаких атрибутов, как было сказано в статье блога.

bash-4.1#     smartctl -a -i -d megaraid,0 /dev/sda

Любая подсказка, что мне здесь не хватает? Как мне получить показатели SMART?
