Driver Installation Instructions
================

This updated driver can be applied using the normal OS installation options.

1 The purpose of this document is to provide clear instructions on how to install OS on drives attached to the Intel(R) IT controller or device.

2 Prepare Installation disk(s)
2.1 Driver files are available on the CD that shipped with the product or can be downloaded from http://www.intel.com/support/ 
2.2 Create install CD(s) from image in disks folder
The driver is provided as CD image (file extension is .iso). To prepare the installation driver CD, a third-party cd burner application to burn image to a CD.

3 Installation methods
There are different types of installation possible with the installation package provided. Those are explained in different sections.

3.1 OS installation on IT/IR

This mode of installation is selected when user needs to install the Operating system on a fresh IT/IR configuration. 
For this kind of installation the driver update CD is used at the starting of the installation and the installer will update the system with driver images for the required kernels. 
Follow the procedure given below to install the driver at the time of Installation.

-----------------
3.1.1 Installing RHEL* 7
-----------------

a) Boot to CD-ROM or DVD-ROM with OS Disk 1.
b) At the Linux installation prompt type: linux dd
c) Press <Enter> at the boot prompt on the Welcome screen.
d) Insert cd made with iso image from step 2.2
e) Select Yes. 
f) Scroll down to select the Intel RAID adapter driver. 
g) The utility locates and loads the driver for your device. 
h) Follow the Red Hat Linux installation procedure to complete the installation.
i) Reboot the system.



-----------------
3.2 Updating driver on already installed system
-----------------

This method is used to update IT/IR driver in a system, which is already installed with an older (or OS embedded) driver version. Here this procedure explains the manual process of updating the driver.  Follow the steps given to update driver.

1) Boot the OS from primary controller/Disk.
2) Copy mptlinux rpm files to a temporary directory in the OS.
3) Query which version of the MPT driver is installed by running the command
	#rpm -qa | grep mpt2sas
4) (If result of step#4 is null, then skip this step.)Remove the bundled version of the MPT driver by running the command
	#rpm -e mpt2sas-<version>-<os>
5) Install the new version of the MPT driver by running the command
	#rpm -ivh mpt2sas-<version>-<release>-<os>.<arch>.rpm
6) Run command line
	#lsmod
to check if mptsas has been loaded successfully.
7) Run command line
	#modinfo mpt2sas
to make sure that the mpt2sas driver version has been updated
8) Completed.
