使用MegaCli和Smartctl获取普通磁盘 - centos通过storcli64和smartctl定位定位硬盘盘位和盘符的方法 - 《Linux 系统命令》

perccli64 show 显示raid卡信息
查看某阵列卡上的的所有磁盘
设备名取 riad group

Section One : Introduction
strocli是megacli的升级版本，针对于戴尔服务器是perccli，用法完全一致
smartctl可以查看磁盘的主控芯片smart信息
lsscsi可以查看系统的scsi信息，数据来源/proc/scsi/scsi相关
这些工具都是查看磁盘相关信息的常用工具，对于排查磁盘状态和raid卡问题都有帮助
Section Two : Install package
安装一下storcli或者perccli，并且将命令软连接到/usr/bin/目录下，方便使用命令：
其实perccli和storccli就是同一个工具，语法完全一样，只是命令名字不一样，适用的品牌不一样。perccli适用于dell机器，storccli适用于华为、浪潮（其它品牌没有测试过，不确认）。下面指令以perccli做示例。顺便贴个下载链接吧。

https://downloads.dell.com/FOLDER03559396M/1/perccli-1.17.10-1.noarch.rpm
https://downloadmirror.intel.com/26820/eng/StorCli.zip
要安装percli RPM，运行rpm -ivh ，或要升级percli RPM，运行rpm -Uvh 。

VD：一般认为是该硬盘在系统里的设备顺序，一般如果只有raid分区，那么VD=0的就是系统里的/dev/sda，VD=1就是/dev/sdb以此类推，但是如果有jbod的分区，先排列jbod分区，如jbod的到了/dev/sdc，VD０则是/dev/sdd，以此类推；
DG：是在raid卡里配置卷组的顺序；

Raid卡日志收集相关命令

storcli64 /c0 show time 显示raid的时间

storcli64 /c0 show alilog logfile=node-x.alilog 获取alilog，所有的log都包括了

storcli64 /c0 show all logfile=node-x.all.log raid卡的信息

storcli64 /c0 show badblocks 磁盘坏道的信息

perccli64 /c0 show events filter=fatal 显示事件级别为fatal的，可以获取所有毁灭性事件的信息，发现磁盘故障或raid卡故障

perccli64 /c0 show cc 数据一致性检测，raid1以上的级别多个盘的数据是需要进行一致性检测的，但是单盘raid0可能是不需要的，是否影响性能不确定

查看磁盘的属性信息

一般此处可以用来查看磁盘的整体健康状态指标参数

针对以下输出信息，字段的解释

ID：属性ID，通常是一个1到255之间的十进制或十六进制的数字。
ATTRIBUTE_NAME：硬盘制造商定义的属性名。
FLAG：属性操作标志（可以忽略）。
VALUE：这是表格中最重要的信息之一，代表给定属性的标准化值，在1到253之间。253意味着最好情况，1意味着最坏情况。取决于属性和制造商，初始化VALUE可以被设置成100或200.
WORST：所记录的最小VALUE。
THRESH：在报告硬盘FAILED状态前，WORST可以允许的最小值，也就是WORST如果小于THRESH,磁盘就会报告FAILED。
TYPE：属性的类型（Pre-fail或Oldage）。Pre-fail类型的属性可被看成一个关键属性，表示参与磁盘的整体SMART健康评估（PASSED/FAILED）。如果任何Pre-fail类型的属性故障，那么可视为磁盘将要发生故障。另一方面，Oldage类型的属性可被看成一个非关键的属性（如正常的磁盘磨损），表示不会使磁盘本身发生故障。
UPDATED：表示属性的更新频率。Offline代表磁盘上执行离线测试的时间。
WHEN_FAILED：如果VALUE小于等于THRESH，会被设置成“FAILING_NOW”；如果WORST小于等于THRESH会被设置成“In_the_past”；如果都不是，会被设置成“-”。在“FAILING_NOW”情况下，需要尽快备份重要文件，特别是属性是Pre-fail类型时。“In_the_past”代表属性已经故障了，但在运行测试的时候没问题。“-”代表这个属性从没故障过。
RAW_VALUE：制造商定义的原始值，从VALUE派生。

Note:

关于以下检测结果，说明检测结果是PASSED的，就是磁盘还可以使用，但是列出了一条检测异常的WORST<THRESH，TYPE是Pre-fail，WHEN_FAILED是In_the_past，说明预测这个盘快坏了。
