100.

查看电池属性（Display Current BBU Properties）

MegaCli -AdpBbuCmd -GetBbuProperties -aN|-a0,1,2|-aALL MegaCli -AdpBbuCmd -GetBbuProperties –aALL

101.

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.
