Monitoring Adaptec RAID controller on Linux

Переписал скрипт для мониторинга Adaptec RAID контролера в Linux, чтобы в случае проблем отсылал сообщение о проблеме на E-mail.

Скрипт мониторинга RAID контролера Adaptec с аргументом mail запускается в кроне каждую минуту и проверяет на наличии ошибок, в случае если ошибка больше 0 отправляется на почту.

Если скрипт запустить с аргументом log, то увидим статус Adaptec RAID контроллера (/var/script/raid/adaptec log).
