Мы уже рассказывали о том как работать и создавать софтварные массивы RAID. Сегодня расскажем о хардварных RAIDах на примере Adaptec 5405.
[ad#ad-2]
Находим информацию об установленных контроллерах RAID. В FreeBSD это можно сделать так:
# dmesg | grep -i RAID aac0: mem 0xe8000000-0xe81fffff irq 16 at device 0.0 on pci6 aacd0: on aac0
или так
# pciconf -l | grep -i aac aac0@pci0:6:0:0: class=0x010400 card=0x02d19005 chip=0x02859005 rev=0x09 hdr=0x00
FreeBSD arcconf
arcconf — утилита для работы с контроллерами RAID из командной строки. Она предназначена для получения детальной информации о RAID включая информацию о «здоровье» массива.
FreeBSD установка arcconf
Очень просто
# portsnap fetch update # cd /usr/ports/sysutils/arcconf # make install clean && rehash
FreeBSD — arcconf — получаем информацию о массиве RAID
Для получения информации о массиве в консоле вводим следующие команды. Пусть наш контроллер имеет номер «1″. Тогда команда такая:
# /usr/local/sbin/arcconf getconfig 1
