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 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

Linux 下默认路径: /opt/MegaRAID/MegaCli/MegaCli64
MegaCli 安装
-
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:
./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)
