Adaptec - снимаем информацию с RAID-контролера

Adaptec логотип

В одном из обслуживаемых серверов, согласно выводу dmesg, установлен RAID-контроллер Adaptec, который FreeBSD распознала как aac0. Выборка из dmesg:

# cat /var/run/dmesg.boot | grep RAID
aac0: Adaptec RAID controller, aac driver 2.1.9-1
aacd0: <RAID 1 (Mirror)> on aac0

Для работы с этим контроллером воспользуемся возможностями утилиты arcconf. Arcconf - утилита для работы с контроллерами RAID из командной строки. С ее помощью можно получить детальную информацию о контроллере и созданных массивах.

Установку, как всегда, выполним из системы портов:

# cd /usr/ports/sysutils/arcconf && make install clean && rehash

Размер дистрибутива "порадовал" - 99 MB. Хорошо, что сервер отдавал дистрибутив на скорости около 20 Mbps. А установка вообще заняла несколько строк. Собственно:

# cd /usr/ports/sysutils/arcconf && make install clean && rehash
=> asm_freebsd_x86_v7_30_18837.tgz doesn't seem to exist in /usr/ports/distfiles/.

После установки утилиты ознакомимся с ее возможностями. Для вывода "хелпа" запустим утилиту без указания ключей:

Как оказалось, один из дисков "вылетел" из массива. Скорей всего кто-то выдернул диск на работающей системе, тоесть "вгорячую". Необходимо пересобирать массив, но это уже тема для отдельной статьи ;)
