linux硬盤管理 raid

  服務器有部分硬盤報警 須要更換 剛接手服務器不知道具體狀況  百度了一些教程 都不盡人意 查詢結果都沒有想要的 

後找到一篇文章 地址 http://blog.csdn.net/msdnchina/article/details/52475383 我這裏只寫與我實際操做有出入的地方 以備複習 
cat /proc/scsi/scsi 
dmesg | grep -i raid

lsi MegaRAID raid卡管理工具能查以下信息:
raid的level,
raid是幾塊物理硬盤構成的,
物理硬盤的製造商.

軟件raid：查看raid級別，狀態等信息
#cat /proc/mdstat
硬件raid：查看raid的廠商，型號，級別
#cat /proc/scsi/scsi
dmesg | grep -i raid

在搜索框裏搜索"megacli",點擊肯定,找到Management Software and Tools (22) 下的 MegaCLI 5.5 P2  (這是命令行工具),另:lsi已經被avago收購了.

這兩個數值來肯定陣列中磁盤是否有問題；Medai Error Count 表示磁盤可能錯誤，多是磁盤有壞道，這個值不爲0值得注意，數值越大，危險係數越高，Other Error Count 表示磁盤可能存在鬆動，可能須要從新再插入。MegaCli 能夠對陣列中全部的磁盤進行檢測，咱們能夠經過腳本的方式來檢測相關參數，從而通知管理人員。
