State : Optimal Strip Size : 128 KB
Number Of Drives per span:4 //表示每4个物理盘做成一个RAID1盘组 Span Depth : 2 //表示共2个RAID1盘组做成了RAID10
89.

92.
93.4、 查看当前raid缓存状态，raid缓存状态设置为wb的话要注意电池放电事宜，
设置电池放电模式为自动学习模式
94./opt/MegaRAID/MegaCli/MegaCli64 -ldgetprop -dskcache -lall -aall
95.
96.5、 raid 电池设置相关

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.
