Какие диски в MegaRAID?

Чтобы узнать какие жесткие диски собраны в RAID-контроллере нам понадобится программа MegaCLI.

Скачаем ее и распакуем:

wget http://www.lsi.com/sep/Documents/oracle/files/Linux_MegaCli_8.02.21.zip
unzip Linux_MegaCli_8.02.21.zip
unzip MegaCliLin.zip

Установим rpm-ки:

rpm -ivh MegaCli-8.02.21-1.noarch.rpm Lib_Utils-1.00-09.noarch.rpm

Сделаем символьные ссылки в /usr/bin для MegaCLI:

ln -s /opt/MegaRAID/MegaCli/MegaCli64 /usr/bin/MegaCli

Проверим работу MegaCLI:

MegaCli -v
