服务器有部分硬盘报警 需要更换 刚接手服务器不知道具体情况  百度了一些教程 都不尽人意 查询结果都没有想要的 

后找到一篇文章 地址 http://blog.csdn.net/msdnchina/article/details/52475383 我这里只写与我实际操作有出入的地方 以备复习  cat /proc/scsi/scsi  dmesg | grep -i raid

lsi MegaRAID raid卡管理工具能查如下信息: raid的level, raid是几块物理硬盘构成的, 物理硬盘的制造商.

软件raid：查看raid级别，状态等信息 #cat /proc/mdstat 硬件raid：查看raid的厂商，型号，级别 #cat /proc/scsi/scsi dmesg | grep -i raid

在搜索框里搜索"megacli",点击确定,找到Management Software and Tools (22) 下的 MegaCLI 5.5 P2  (这是命令行工具),另:lsi已经被avago收购了.

以下是MegaCli使用命令

这两个数值来确定阵列中磁盘是否有问题；Medai Error Count 表示磁盘可能错误，可能是磁盘有坏道，这个值不为0值得注意，数值越大，危险系数越高，Other Error Count 表示磁盘可能存在松动，可能需要重新再插入。MegaCli 可以对阵列中所有的磁盘进行检测，我们可以通过脚本的方式来检测相关参数，从而通知管理人员。 Predictive Failure Count: 0 Last Predictive Failure Event Seq Number: 0 PD Type: SAS
