Introduction

Centrally managing your storage is nice - especially when you’ve just built your own SANs (or such). I created a synchronous replicating SAN cluster using LSI MegaRAID 9270-8i cards in 2x Dell R720XD chassis built on openSUSE 12.3 (more on that in another article soon).

We are migrating from 2x Dell MD3000i to these beasts built on a pure-cli OS. Some people like GUIs and that’s okay - so for day-to-day admin, email reporting on problems and basic configuration and tasks LSI offer (free) MegaRAID Storage Manager. It works much in the same way as Dell’s MD Storage Manager that we currently use for the MD3000i but (obviously) without the ability to create iSCSI LUNs etc as they are managed by the OS, not the RAID card.

So, to get rolling we need to log into openSUSE, and sudo bash your way in there.

Installing

We need to create a temp directory, download LSI MSM for Linux (x64) into it, extract it and install:

mkdir temp
cd temp/
wget "http://www.lsi.com/downloads/Public/MegaRAID%20Common%20Files/13.08.04.01_Linux(64)_MSM.tar.gz"
tar zxvf 13.08.04.01_Linux(64)_MSM.tar.gz
cd disk/

We need to install net-snmp as a prerequisite:

zypper install net-snmp

Then go ahead and install MSM server agent (the component that reports back to the management client):

./install.csh -d

See below for complete trigger reference:

./install.csh -h
Usage : install.sh [-option]
The options are :
              a
                The Complete Installation of MegaRAID Storage Manager (MSM) 
              c
                The Client components only program of MSM
              s
                The StandAlone component of MSM
              l
                The Local component of MSM
              d
                The Server component of MSM
              au
                The upgrade only option for Complete MSM
              cu
                The upgrade only option for Client only MSM
              su
                The upgrade only option for Standalone MSM
              lu
                The upgrade only option for Local MSM
              du
                The upgrade only option for Server MSM

If all is well you’ll see this:

./install.csh -d

Let’s install the MSM Management GUI on our Windows/[Linux]x641 box, just run through the installer, this time you just need client installed.

Managing Storage

Open up MegaRAID Storage Manager and click Configure Host, change the radio button to be Display all systems in the network of local server and press Save Settings. It will then scan your local network for hosts:

Adding hosts

Click the host and log in with your root account:

Managing storage

All the metrics, visuals and nice fancy views you could ever desire, along with the ability to manage and rebuild arrays, configure volume groups and all the stuff listed here. Enjoy!
