The reason the command does not show up without full path is because the path to the binary is not included in the users PATH variable. If you see the output as above, it means the binary is present. MegaCLI SAS RAID Management Tool Ver 8.07.14 (c)Copyright 2013, LSI Corporation, All Rights Reserved. Try executing the below command # /opt/MegaRAID/MegaCli/MegaCli64 -v In CentOs machines, the binary is installed at /opt/MegaRAID/MegaCli/MegaCli64 The path and name to access the utility might be different. This doesn’t necessarily mean that MegaCli is absent. usr/bin/which: no MegaCli in (/usr/local/ /sbin/usr/local/bin:/usr/sbin:/usr/bin:/opt/cpanel/composer/bin:/root/bin') Otherwise, skip to Step 3įor Centos Machines, you may get an error like ~]#MegaCli The below instructions are to be read only if megacli is not found. If for some reason the path to the binary is different like /usr/sbin/MegaCli etc, then modify the script and commands below by replacing all instances of /sbin/MegaCli with the correct path to binary. You can do that by issuing the which MegaCliĪs you already knew, the binary paths can vary according to the installations. Login to the client server or the server to be monitored as root user Step 2:īefore moving forward, verify the path to MegaCli. Now let us move to the step by step instructions to enable RAID Monitoring on Nagios.

#OPEN SOURCE RAID MONITOR MANUAL#

MegaCLI is a command line interface (CLI) binary used to communicate with the full LSI family of raid controllers.įor a complete reference either call MegaCli -h or refer to the manual at:

#OPEN SOURCE RAID MONITOR HOW TO#

Here we are focusing our discussion only on the configuration of RAID check.īefore delving into how to add the check, lets first look at what MegaCli is. I assume that you already configured a Nagios server for server monitoring using NRPE plugin and are familiar with its working.

This article is to highlight the steps to be followed to add raid check for servers using the `MegaCli` utility. While majority of the disk checks can be performed through simple tweaking of the existing commands, Raid disk health evaluation demands some advanced level of operations due to the architecture and raid controller differences with each RAID setup.

#OPEN SOURCE RAID MONITOR SOFTWARE#

To administer the Software RAID using webmin login as a sudo-er, go to the page Hardware > Linux RAID and play around.During a Nagios monitoring implementation, we often need to depend NRPE plugins and custom commands to execute server monitoring tasks such as load monitoring, disk usage monitoring etc. Use your browser to access your webmin panel at the following url: mdadm through Webmin Issue the following commands: $ sudo apt-get updateģ) Visit your Webmin administration panel On Ubuntu, create the following file: /etc/apt//webmin.list and add the following lines to it: # Repository for Webmin Installation on a Debian-based Linux distribution, such as Ubuntu is trivial.ġ) Add the appropriate repository to your apt.sources list. UUID : ae9a0180:107c7d2a:85e38229:c66e1e31Ī GUI for mdadm is provided by Webmin, the browser-based administrative suite. This is especially hard on new users, because the CLI commands for monitoring your array give rather cryptic results. This leaves us without a graphical user interface to mdadm.

#OPEN SOURCE RAID MONITOR CODE#

Despite the fact that there is a registered Sourceforge project called mdadm-GUI, there is no code in it and it seems that no work is currently being done.

Mdadm is a wonderful Linux utility, which allows you to set up a software RAID array. Using RAID makes your backup strategy completely transparent and your data safe and happy. If you are technical enough to build your own NAS, or if you run Linux on your desktop, you probably know about RAID, fake RAID, and software RAID. This redundancy can be achieved by keeping various backups, but it’s clear that the only backup scheme which works is the “set it and forget it” kind. Anybody who cares about their data understands, that data “is not safe, unless it exists in at least two copies”.
