A common nightmare for system administrators is when a hard disk fail which puts the RAID array in degraded mode. Depending on the number of HDDs installed and the RAID configuration of your server, the data reside on your server is at risk and therefore prompt action is required to prevent downtime and data loss.

How To Install StorCLI on Linux

For the purpose of this article we will follow the steps and commands on a Linux CentOS 7 server.

Step 1: Download StorCLI

The latest version of StorCLI can be downloaded for free from the Intel website.

Login as root on your Linux server and type the following command:

wget https://downloadmirror.intel.com/30394/eng/StorCLI_007.1513.0000.0000.zip

If ‘wget’ is not installed you can do so like this:

yum install wget

Step 2: Unzip & Install StorCLI RPM File

As soon as the zip file has finished downloading, unzip it using the following command:

unzip StorCLI_007.1513.0000.0000.zip

If ‘unzip’ is not installed, you can do so with the following command:

yum install unzip

At this point we need to enter the unzipped folder and locate the file storcli-007.1513.0000.0000-1.noarch.rpm under the ‘Linux’ sub-folder, as follows:

cd ~/StorCLI_007.1513.0000.0000/Linux

Now use the following command to install StorCLI:

rpm -ivh storcli-007.1513.0000.0000-1.noarch.rpm

Congratulations! StorCLI has been successfully installed on your Linux server and the binary file is located at /opt/MegaRAID/storcli/storcli64
