服务器评测
操作系统自带的命令查看RAID：
软件raid：查看raid级别，状态等信息 【生产环境没人敢用软raid，除非他不想干了】
# cat/proc/mdstat
硬件raid：查看raid的厂商，型号，级别
# dmesg |grep -i raid
# cat/proc/scsi/scsi
DELL服务器 使用MegaCli64查看RAID：
安装
# rpm-ivh MegaCli64-8.07.14-1.noarch.rpm
默认是安装到/opt/MegaRAID目录下了。
cd /opt/MegaRAID/MegaCli
执行./MegaCli64 -LDInfo -LAll-aAll —-> 常用
#./MegaCli64 -LDInfo -Lall -aALL 查raid级别
#./MegaCli64-AdpAllInfo -aALL 查raid卡信息
#./MegaCli64 -PDList -aALL 查看硬盘信息 —-> 常用
#./MegaCli64 -AdpBbuCmd -aAll 查看电池信息
#./MegaCli64-FwTermLog -Dsply -aALL 查看raid卡日志
#./MegaCli64-adpCount 【显示适配器个数】
#./MegaCli64-AdpGetTime –aALL 【显示适配器时间】
#./MegaCli64-AdpAllInfo -aAll 【显示所有适配器信息】
#./MegaCli64-LDInfo -LALL -aAll 【显示所有逻辑磁盘组信息】
#./MegaCli64-PDList -aAll 【显示所有的物理信息】
#./MegaCli64-AdpBbuCmd -GetBbuStatus -aALL |grep ‘Charger Status’ 【查看充电状态】
#./MegaCli64-AdpBbuCmd -GetBbuStatus -aALL【显示BBU状态信息】
#./MegaCli64-AdpBbuCmd -GetBbuCapacityInfo -aALL【显示BBU容量信息】
#./MegaCli64-AdpBbuCmd -GetBbuDesignInfo -aALL 【显示BBU设计参数】
#./MegaCli64-AdpBbuCmd -GetBbuProperties -aALL 【显示当前BBU属性】
#./MegaCli64-cfgdsply -aALL 【显示Raid卡型号，Raid设置，Disk相关信息】
3.磁带状态的变化，从拔盘，到插盘的过程中。
Device |Normal|Damage|Rebuild|Normal
VirtualDrive |Optimal|Degraded|Degraded|Optimal
PhysicalDrive |Online|Failed –>Unconfigured|Rebuild|Online
4.查看磁盘缓存策略
#./MegaCli64-LDGetProp -Cache -L0 -a0
or
#./MegaCli64-LDGetProp -Cache -L1 -a0
or
#./MegaCli64-LDGetProp -Cache -LALL -a0
ro
#./MegaCli64-LDGetProp -Cache -LALL -aALL
ro
#./MegaCli64-LDGetProp -DskCache -LALL -aALL
5.设置磁盘缓存策略
缓存策略解释：
WT (Write through
WB (Write back)
NORA (No read ahead)
RA (Read ahead)
ADRA (Adaptive read ahead)
Cached
Direct
例子：
#./MegaCli64-LDSetProp WT|WB|NORA|RA|ADRA -L0 -a0
or
#./MegaCli64-LDSetProp -Cached|-Direct -L0 -a0
or
enable /disable disk cache
#./MegaCli64-LDSetProp -EnDskCache|-DisDskCache -L0 -a0
6.创建一个raid5 阵列，由物理盘2,3,4 构成，该阵列的热备盘是物理盘5
#./MegaCli64-CfgLdAdd -r5 [1:2,1:3,1:4] WB Direct -Hsp[1:5] -a0
7.创建阵列，不指定热备
#./MegaCli64-CfgLdAdd -r5 [1:2,1:3,1:4] WB Direct -a0
8.删除阵列
#./MegaCli64-CfgLdDel -L1 -a0
9.在线添加磁盘
#./MegaCli64-LDRecon -Start -r5 -Add -PhysDrv[1:4] -L1 -a0
10.阵列创建完后，会有一个初始化同步块的过程，可以看看其进度。
#./MegaCli64-LDInit -ShowProg -LALL -aALL
或者以动态可视化文字界面显示
#./MegaCli64-LDInit -ProgDsply -LALL -aALL
11.查看阵列后台初始化进度
#./MegaCli64-LDBI -ShowProg -LALL -aALL
或者以动态可视化文字界面显示
#./MegaCli64-LDBI -ProgDsply -LALL -aALL
12.指定第5 块盘作为全局热备
#./MegaCli64-PDHSP -Set [-EnclAffinity] [-nonRevertible] -PhysDrv[1:5] -a0
13.指定为某个阵列的专用热备
#./MegaCli64-PDHSP -Set [-Dedicated [-Array1]] [-EnclAffinity] [-nonRevertible]-PhysDrv[1:5] -a0
14.删除全局热备
#./MegaCli64-PDHSP -Rmv -PhysDrv[1:5] -a0
15.将某块物理盘下线/上线
#./MegaCli64-PDOffline -PhysDrv [1:4] -a0
#./MegaCli64-PDOnline -PhysDrv [1:4] -a0
16.查看物理磁盘重建进度
#./MegaCli64-PDRbld -ShowProg -PhysDrv [1:5] -a0
或者以动态可视化文字界面显示
#./MegaCli64-PDRbld -ProgDsply -PhysDrv [1:5] -a0
