Full Description


Docker container for running MegaCLI and StorCLI on Debian / Ubuntu / RedHat / CentOS

Using MegaCLI

MegaCLI is a very complicated tool that requires you to enter case-sensitive arguments
that seem to have no rhyme or reason. It is virually impossible to guess a command,
and even the executable MegaCli can be found spelled in many different cases. To add
to the madness, there is abysmal support for Debian-based distros like Ubuntu. Since
this container runs CentOS inside a Docker container, it can run seemlessly on Ubuntu
from the CentOS runtime and RPM package.

Note: There is a similar command called StorCLI, also made by LSI. This command is
also included as storcli inside this container.

Running the container

You can run this container without installing anything except Docker:

docker run --rm -ti --privileged kamermans/docker-megacli

Note that the --rm will delete the container for you when you exit it, and
privileged mode is required so the container can talk directly to the hardware.

Once you start the container, you will find yourself at a bash prompt:

steve@steve-hq:~$ docker run --rm -ti --privileged kamermans/docker-megacli

      MegaCLI SAS RAID Management Tool  Ver 8.07.14 Dec 16, 2013
      Storage Command Line Tool  Ver 1.03.11 Jan 30, 2013

[root@ed2f45d425f2 megacli]#

You are dropped into the /megacli directory, which has lots of helpful scripts in it
to get you going:

[root@ed2f45d425f2 megacli]# ls -1

Note: All of the scripts are non-destructive, they simply show you information about
your RAID Controller.

This directory (/megacli) is in your PATH, so you can run those commands from anywhere.
You should probably start by taking a look at the controller summary:

[root@ed2f45d425f2 megacli]# show_summary

        Operating System:  Linux version 3.16.0-49-generic
        Driver Version: 06.803.01.00-rc1
        CLI Version: 8.07.14

                 ProductName       : PERC H700 Integrated(Bus 0, Dev 0)
                 SAS Address       : 5782bcb0204ea700
                 FW Package Version: 12.3.0-0032
                 Status            : Need Attention
                 BBU Type          : BBU
                 Status            : Replace Battery pack        PD

Well, it seems my battery (BBU) is dead, great.

Let's see how this script works:

[root@ed2f45d425f2 megacli]# cat show_summary
#!/bin/sh -e

MegaCli -ShowSummary -aALL

As you can see, these scripts are mostly one-liners that you could also run manually.

You can get a full list of the MegaCLI commands with man megacli. It is a huge,
virtually-uncommented list of commands, so you probably want to check out a cheat
sheet for more information, so try show_cheat_sheet_urls:

[root@ed2f45d425f2 megacli]# show_cheat_sheet_urls

Updating the container

You can update this container with docker pull:

docker pull kamermans/docker-megacli
