解包下来后，有个 Megamon-4.0-0a.i386.rpm 安装结束后 /etc/init.d/raidmon start
# tail -f /var/log/megaserv.log 就可以看到检测报告。有问题的时候，此log中会有体现。
还可以编辑 /etc/megamon.conf ，将管理员的信箱加在文件末尾，这样检测到错误的时候，会自动发送邮件。
(mail.35.cn 好象当成垃圾邮件过滤掉了)
因此建议 megarc(手工) 配合 raidmon(自动) 是个比较好的解决方案。 Dell 1950 的 PERC 5/i SAS RAID 控制器用这个命令行工具： MegaCLI for Linux
