How to restrict Amazon s3 bucket access permissions for a user

This article explains how to install CentOS Linux on HP ProLiant ML10 and also installing the Linux drivers for Smart Array B110i SATA with RAID 1. We will be installing Centos 5.7 in this example. As the driver for the storage controller is not there in Centos by default, We need to create usbkey with required drivers and specify the path while the installation starts. Well. Its not that complicated.


First we need to download the required drivers from here. As we are using 5.7 in this example I have downloaded this.

hpahcisr-1.2.6-16.rhel5u7.x86_64.dd.gz

Now, we have to create a usbkey.
From a linux system unzip the downloaded driver image.

#gunzip hpahcisr-1.2.6-16.rhel5u7.x86_64.dd.gz

You will get,
hpahcisr-1.2.6-16.rhel5u7.x86_64.dd

Now burn the file to the usb drive
suppose usb drive is detected as /dev/sdc (check, be carefull)
fdisk -l will tell you ab
out the device name of the usb stick. Sometimes you may need to use sudo.

Run the following command
#dd if=hpahcisr-1.2.6-16.rhel5u7.x86_64.dd of=/dev/sdc


Now
Boot the HP ProLiant ML10 Server with usb plugged in and Centos/Redhat 5u7 DVD inserted.

On the first boot screen :

Now the system started loading the driver.

You will get the window to select the storage media available for installation. remove the usb stick and proceed with the installation.

Because we installed the driver for storage controller it is showing only one storage device with 1TB capacity(raid 1). It the driver is not installed then it wll show the two different drivers with 1TB each capacity.
