设置电池为学习模式为循环模式（Start BBU Learning Cycle）

Description Starts the learning cycle on the BBU. No parameter is needed for this option.

MegaCli -AdpBbuCmd -BbuLearn -aN|-a0,1,2|-aALL

102.

设置磁盘的缓存模式和访问方

式 （Change Virtual Disk Cache and Access Parameters）

Description Allows you to change the following virtual disk parameters: -WT (Write through), WB (Write back): Selects write policy.

-NORA (No read ahead), RA (Read ahead), ADRA (Adaptive read ahead): Selects read policy.

-Cached, -Direct: Selects cache policy. -RW, -RO, Blocked: Selects access policy. -EnDskCache: Enables disk cache. -DisDskCache: Disables disk cache.

MegaCli -LDSetProp { WT | WB|NORA |RA | ADRA|-Cached|Direct} | {-RW|RO|Blocked} | {-Name[string]} |

{-EnDskCache|DisDskCache} –Lx | -L0,1,2|-Lall -aN|-a0,1,2|-aALL MegaCli -LDSetProp WT -L0 -a0

103.

显示磁盘缓存和访问方式（Display Virtual Disk Cache and Access Parameters）

MegaCli -LDGetProp -Cache | -Access | -Name | -DskCache -Lx|-L0,1,2| -Lall -aN|-a0,1,2|-aALL

Displays the cache and access policies of the virtual disk(s): -WT (Write through), WB (Write back): Selects write policy.

-NORA (No read ahead), RA (Read ahead), ADRA (Adaptive read ahead): Selects read policy.

-Cache, -Cached, Direct: Displays cache policy. -Access, -RW, -RO, Blocked: Displays access policy. -DskCache: Displays physical disk cache policy.

104.

105. Megaraid 必知必会 使用LSI的megaraid可以对raid进行有效监控。别的厂商比如HP,IBM也有自己的raid API MegaCli -ldinfo -lall -aall

查询raid级别，磁盘数量，容量，条带大小。 MegaCli -cfgdsply -aALL |grep Policy 查询控制器cache策略

MegaCli -LDSetProp WB -L0 -a0 设置write back功能

MegaCli -LDSetProp CachedBadBBU -L0 -a0 设置即使电池坏了还是保持WB功能 MegaCli -AdpBbuCmd -BbuLearn a0 手动充电

MegaCli -FwTermLog -Dsply -aALL 查询日志

显示适配器个数： MegaCli -adpCount

显示所有适配器信息： MegaCli -AdpAllInfo -aAll Critical Disks : 0 Failed Disks : 0

显示所有逻辑磁盘组信息： MegaCli -LDInfo -LALL -aAll 显示所有的物理信息： MegaCli -PDList -aAll

Media Error Count: 0 Other Error Count: 0

查看充电状态： MegaCli -AdpBbuCmd -GetBbuStatus -aALL Learn Cycle Requested : No Fully Charged : Yes

显示BBU(后备电池)状态信息： MegaCli -AdpBbuCmd -GetBbuStatus -aALL

显示BBU容量信息： MegaCli -AdpBbuCmd -GetBbuCapacityInfo -aALL

显示BBU设计参数： MegaCli -AdpBbuCmd -GetBbuDesignInfo -aALL 显示当前BBU属性： MegaCli -AdpBbuCmd -GetBbuProperties -aALL 显示Raid卡型号，Raid设置，Disk相关信息： MegaCli -cfgdsply -aALL 查看Cache 策略设置： MegaCli -cfgdsply -aALL |grep -i Policy Current Cache Policy: WriteBack, ReadAheadNone, Direct, Write Cache OK if Bad BBU

查看充电进度百分比： MegaCli -AdpBbuCmd -GetBbuStatus -aALL

各种设备和磁盘的不同状态：

Device |Normal|Damage|Rebuild|Normal

Virtual Drive |Optimal|Degraded|Degraded|Optimal

Physical Drive |Online|Failed –> Unconfigured|Rebuild|Online 106. 107. 108. 109. 110. 111. 112. 113. 114. 115. 116. 117. 118. 119. 120. 121. 122. 123. 124.

6、 通过脚本检测RAID 磁盘状态 Linux下脚本 #!/bin/bash #check raid disk status

MEGACLI=\

$MEGACLI -pdlist -aALL | grep \

rint $1}' >/tmp/fireware.log

$MEGACLI -pdlist -aALL | grep -E \>/tmp/disk.log

for i in `cat < /tmp/disk.log` do if [ $i -ne 0 ] then

curl \ fi done

for i in `cat < /tmp/fireware.log` do

if [ $i != Online ] then

curl \

125. 126. 127. 128. 129. 130. 131. 132. 133. 134. 135. 136. 137. 138. 139. 140. 141. 142. 143. 144. 145. 146. 147. 148. 149. 150. 151.

fi done

Windows 下脚本

Windows下脚本用的工具是gnu for windows平台的一些软件，

如 bash grep awk cat

通过bash直接调用脚本

如：G:\\raid_check\%unixtools>bash.exe G:\\disk.sh #check raid disk status

MEGACLI=\ GREP=\ AWK=\ CAT=\ CURL=\

$MEGACLI -pdlist -aALL | $GREP \

F , '{print $1}' >//c/fireware.log

$MEGACLI -pdlist -aALL | $GREP -E \$2}' > //c/disk.log

for i in `$CAT c:/disk.log` do if [ $i -ne 0 ] then

$CURL \ fi done

for i in `$CAT c:/fireware.log` do

if [ $i != Online ] then

$CURL \ fi
