-====== LSI MegaRaid - Automatische Überwachung des RAID Status und der Festplatten per Script ======
-Es gibt zur Zeit keine vernünftige Hersteller-Lösung für dieses Problem. Daher habe ich ein eigenes Script hierfür entwickelt.
- --- //[[mail@awerner.myhome-server.de|Axel Werner]] 2009-04-08 17:13//
-===== Requirements / Vorraussetzungen =====
-  * ein korrekt konfigurierter lokaler MTA (Exim / Postfix) zum absetzen vom Status-Emails
-  * [[it-artikel:linux:lsi-megaraid-cli-utility-fuer-sas-raid-controller|MegaCLI Kommandozeilen Tool]]
-  * awk interpreter
-===== Installation =====
-  - Alle nachfolgend gezeigten Files und Scripte nach /etc kopieren.
-  - Das *.sh Shellscript ausführbar machen
-  - Den Aufruf für das Shellscript in /etc/crontab einfügen. z.B.
-<code|/etc/crontab>
-#RAID System Zustandsueberwachung alle 30 Minuten
-*/30 * * * *	root	/etc/raid-checker.sh
