Управление RAID на RHEL4

[alibek]

Есть старый сервер Dell PowerEdge 2950 с RHEL4.

На сервере установлен RAID-контроллер LSI Logic SAS based MegaRAID 1078, к нему подключены 4 диска, объединенных в RAID5, которые смонтированы в LVM.

Можно ли как-то просмотреть состояние RAID-котроллера и массивов? Я подозреваю, что на RAID-контроллере сдохла батарейка и выключился кеш записи.

Можно . У меня стоит LSI Logic / Symbios Logic MegaRAID SAS 2208. Через megacli получаю данные . Скрипт вызывает zabbix

 

Утилита

 

mkdir MegaCLI
$ cd MegaCLI/
$ wget http://www.lsi.com/downloads/Public/RAID%20Controllers/RAID%20Controllers%20Common%20Files/8.07.14_MegaCLI.zip

unzip 8.07.14_MegaCLI.zip

 

 

megacli -AdpAllInfo -aAll

 

 cd Linux/
rpm -ihv MegaCli-8.07.14-1.noarch.rpm

Zabbix

Ага, спасибо, помогло.

Правда сайт www.lsi.com уже неживой, но я нашел зеркало.
