strocli64 源码_storcli64和smartctl定位硬盘的故障信息
定位硬盤盤位和盤符的方法
from lin.wang
section one : introduction
strocli是megacli的升級版本，針對于戴爾服務器是perccli，用法完全一致
smartctl可以查看磁盤的主控芯片smart信息
lsscsi可以查看系統的scsi信息，數據來源/proc/scsi/scsi相關，該文檔此處暫不介紹
這些工具都是查看磁盤相關信息的常用工具，對于排查磁盤狀態和raid卡問題都有幫助
section two : install package
安裝一下storcli或者perccli，并且將命令軟連接到/usr/bin/目錄下，方便使用命令：
ln -s /opt/megaraid/storcli/storcli64 /usr/bin/
ln -s /opt/megaraid/perccli/percclie64 /usr/bin/
section three : step
由系統磁盤盤符/dev/sdf定位對應的硬盤盤位思路如下：
perccli64 /c0/eall/sall show 看到該磁盤有
img-/c0/eall/sall
從該圖看到有四個jbod分區，根據經驗一般人為jbod的分區系統盤符會在raid分區之前，也就是說jbod的分區會從/dev/sda > /dev/sdd，raid的分區從/dev/sde開始；
dg代表drive group，是配置raid建分組的順序，有圖上看到32:4和32:5是一個卷組。
perccli64 /c0/vall show看到該磁盤的dg與vd的對應關系如下
img-/c0/vall
? 由圖上看到dg/vd就是raid的卷組和系統里卷組的順序對應關系，一般如果服務器只有raid卷組來說的話，vd0就是操作系統里的/dev/sda，以此類推；但是如果服務器包括了jbod卷組，則raid的卷組從jbod后開始排序，本例中也就是vd0＝/dev/sde，則要定位/dev/sdf的話vd＝１，對應dg＝１；
? 回到img-/c0/eall/sall上，dg為1時，did=6，did就是device id，這個概念后邊有用；同時slot no.也就是slt = 6對應的服務器上盤位就是第７個(從0開始到6)，此時即定位到了/dev/sdf的物理盤位。
反之從服務器上看到硬盤故障燈，可以反推對應的系統分區盤符
note:
? 如果服務器沒有jbod卷組，全是raid的，則此時/c0/vall找到對應關系即可定位關聯關系
? 實際操作時還可以通過 perccli64 /c0/e32/s6 start/stop locate點亮關閉磁盤燈，來判斷定位是否正確

perccli64 show ctrlcount 查看有幾個控制器即幾個raid卡
perccli64 show 顯示raid卡信息

note:
vd：一般認為是該硬盤在系統里的設備順序，一般如果只有raid分區，那么vd=0的就是系統里的/dev/sda，vd=1就是/dev/sdb以此類推，但是如果有jbod的分區，先排列jbod分區，如jbod的到了/dev/sdc，vd０則是/dev/sdd，以此類推；
dg：是在raid卡里配置卷組的順序；
raid卡日志收集相關命令
storcli64 /c0 show time 顯示raid的時間
storcli64 /c0 show alilog logfile=node-x.alilog 獲取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 磁盤壞道的信息
perccli64 /c0 show events filter=fatal 顯示事件級別為fatal的，可以獲取所有毀滅性事件的信息，發現磁盤故障或raid卡故障
perccli64 /c0 show cc 數據一致性檢測，raid1以上的級別多個盤的數據是需要進行一致性檢測的，但是單盤raid0可能是不需要的，是否影響性能不確定

查看磁盤的屬性信息
一般此處可以用來查看磁盤的整體健康狀態指標參數
針對以下輸出信息，字段的解釋
id：屬性id，通常是一個1到255之間的十進制或十六進制的數字。
attribute_name：硬盤制造商定義的屬性名。
flag：屬性操作標志(可以忽略)。
value：這是表格中最重要的信息之一，代表給定屬性的標準化值，在1到253之間。253意味著最好情況，1意味著最壞情況。取決于屬性和制造商，初始化value可以被設置成100或200.
worst：所記錄的最小value。
thresh：在報告硬盤failed狀態前，worst可以允許的最小值，也就是worst如果小于thresh,磁盤就會報告failed。
type：屬性的類型(pre-fail或oldage)。pre-fail類型的屬性可被看成一個關鍵屬性，表示參與磁盤的整體smart健康評估(passed/failed)。如果任何pre-fail類型的屬性故障，那么可視為磁盤將要發生故障。另一方面，oldage類型的屬性可被看成一個非關鍵的屬性(如正常的磁盤磨損)，表示不會使磁盤本身發生故障。
updated：表示屬性的更新頻率。offline代表磁盤上執行離線測試的時間。
when_failed：如果value小于等于thresh，會被設置成“failing_now”；如果worst小于等于thresh會被設置成“in_the_past”；如果都不是，會被設置成“-”。在“failing_now”情況下，需要盡快備份重要文件，特別是屬性是pre-fail類型時。“in_the_past”代表屬性已經故障了，但在運行測試的時候沒問題。“-”代表這個屬性從沒故障過。
raw_value：制造商定義的原始值，從value派生。

補充
如果沒有開啟磁盤的smart可以通過-s on device開啟
一般來說如果samrtctl -i 獲取info時沒有什么信息輸出且smart support是允許的可用的，那么說明可能需要做test才能獲取到-t short/long，該測試不會破壞硬盤上的數據，但對于存儲一般不適用離線offline測試
收集時可以通過-x -a參數獲取更全面的磁盤信息
smartctl是可以配置服務的/etc/smartmontools/smartd.conf，對此目前沒有研究，后續有研究成果再更新
如您對本文有疑問或者有任何想說的，請點擊進行留言回復，萬千網友為您解惑！
