常用检查 磁盘erro

/opt/MegaRAID/MegaCli/MegaCli64 -pdlist -a0|grep -Ei "enc|Slot Number|Firmware stat|media error |other error"

raid一致性检查

禁用一直性 检查
/opt/MegaRAID/MegaCli/MegaCli64 -AdpCcSched -Dsbl -Aall
启用一致性检查，
/opt/MegaRAID/MegaCli/MegaCli64 -AdpCcSched -ModeConc -Aall
查看一直性检查 信息
/opt/MegaRAID/MegaCli/MegaCli64 -AdpCcSched -info -Aall

在pdlist 中可以看到 硬盘类型

Media Type: Hard Disk Device，，如果是固态盘，会显示 solid state device
PD Type: SAS，，这个应该可以判断是 sata盘 还是sas盘。。

flush raid cache

闪烁硬盘

MegaCli -PdLocate -start -physdrv [E:S] -aALL

write back 只对写有用。
BBu状态 会影响到 write back 模式 是否开启。
