3 нужных команды для управления RAID на сервере DELL

от

Все заклинания следует делать из директории в которой лежит бинарник perccli64. Ну или если ты его прописал в PATH, то из любого другого места (не забудь тогда убрать ./ перед командой).

Самая главная команда:


./perccli64 show all

Поведает нам номер контроллера и его состояние.

посмотреть состояние и настройки логического диска можно так:
./perccli64 /c0/v0 show all

на что получишь примерно вот такое:

[root@ats perccli]# ./perccli64 /c0/v0 show all

хелп у данной утилиты очень краткий, но как подсказка прокатит:

./perccli64 help

вывод показывать не буду, там всего и много.

Логика утилиты достаточно простая, в пояснениях не нуждается.
