MegaCli 是 LSI 公司官方提供的 SCSI 卡管理工具，由于 LSI 被收购变成了现在的 Broadcom，所以想下载 MegaCli，需要去 Broadcom 官网查找。现在官方有 Storcli，整合了 LSI 和 3ware 所有产品，本文主要以 MegaCli64 为例，无论选择 MegaCli 还是 Storcli 只要在线上环境运行稳定可以获取正确数据就都是合适的方法。

Extracting the RAID-Controller Logs via MegaCLI
MegaRaid 阵列卡管理工具。他可以查看当前 RAID 卡的所有信息，包括 RAID 卡型号、类型、磁盘状态、电池状态等等。学会了如何使用 MegaCli，我们可以在硬盘没有彻底嗝屁（ Failed ）之前，监测到是否已经出现预告警报错，不需要现场逐台巡检磁盘状态灯。

Linux 下默认路径: /opt/MegaRAID/MegaCli/MegaCli64
Download the MegaCli utility from the Broadcom support site
Unzip the downloaded files and install them to any directory of your installed operating system (e.g.: Linux – /tmp/megacli)
From a terminal window in Linux, install the using the the following command:
Note: root priviledges required to install MegaCLI:
rpm -i MegaCli-8.07.14-1.noarch.rpm
Then change directory into /opt/MegaRAID/MegaCLI/ and run any of the commands from the table below:
|Command |Action |
| --- | --- |
|./MegaCli64 -FwTermLog -Dsply -aALL > /tmp/ttylog.txt |Creates the RAID controller log (ttylog) |
|./MegaCli64 -PDList -aALL > /tmp/disks.txt |Creates a list with information about the RAID controllers, virtual disks and hard disks installed |
|./MegaCli64 -LDInfo -LALL -aALL > /tmp/LDinfo.txt |Creates a list with information about existing RAID volumes and configurations |
|./MegaCli64 -AdpAllInfo -aALL > /tmp/Adapterinfo.txt |Creates a list with information about RAID controller settings |
|./MegaCli64 -AdpBbuCmd -aALL > /tmp/Battery.txt |Creates a detailed list of the battery status of the RAID controller (state of charge, learning cycle, etc.) |
|./MegaCli64 -AdpEventLog -IncludeDeleted -f deleted.txt -aALL |Creates the RAID controller log (ttylog) with all information since very first controller initialization( Note: This file will always be saved in the MegaCLI root folder) |
