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。

MegaCLI vs tw_cli vs Storcli
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。

  1. 使用 Zabbix 监控硬盘或者使用 IPMI 接入 OOB(Out-of-Band) 监控硬件状态
  2. 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

MegaCli64 官网地址: http://docs.avagotech.com/docs/12351587

Linux 下默认路径: /opt/MegaRAID/MegaCli/MegaCli64

MegaCli 安装

  1. Download the MegaCli utility from the Broadcom support site

  2. Unzip the downloaded files and install them to any directory of your installed operating system (e.g.: Linux – /tmp/megacli)

  3. 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

  4. 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)
