Скачиваем, распаковываем и импортируем шаблон

zabbix2-lsimegaraid-template.zip

Добавляем шаблон к хосту, на котором мониторим LSI Megaraid
Проверяем, что через 1-2 минуты на хосте появились Items с именем LSI Megaraid
Monitoring->Latest Data->фильтруем по требуемому хосту в поле Hosts-> LSI Megaraid
