前言
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
MegaCli简介
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。
- 使用Zabbix监控硬盘或者使用IPMI接入OOB(Out-of-Band)监控硬件状态
- 使用更加成熟的商业化工具管理如云霁科技CloudBoot，拒绝被单一厂商绑架

| 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) |
