I was looking at buying a cheap NAS but than I saw a good deal on a used EX475 and decided why not use this instead of a cheap NAS.

Here is my project.

Install CentOS 6 and setup RAID1.

Drive config will look like this

80 GB Western Digital boot disk.
2x1 TB Western Digital RE4 drives.

As per ... 7&start=15 it appears a driver exists for the NIC.

So I worte this bash script


#Setup Drivers
echo alias eth0 sis190 >> /etc/modprobe.conf
echo modprobe sis190 >> /etc/rc.modules

When you move a hard drive to a new machine the mac address to the old NIC will be left behind so you need to remove the /etc/udev/rules.d/70-persistent-net.rules file to force it to re-generate so to remove it

rm -rfv /etc/udev/rules.d/70-persistent-net.rules

Hopefully on the next boot which will be the media smart that file will be re-generated.

However, The NIC will still need to be configured so hopefully once the driver is loaded into the kernel I'll be able to blindly run this bash script to setup the network.

Yes, I know to replace with the proper IP's


#Setup Varables
MAC=`ifconfig -a | grep HWaddr | head -1 | awk {'print$5'}`
export IP=
export NETMASK=
export GATEWAY=

#Configure eth0
echo DEVICE=eth0 > /etc/sysconfig/network-scripts/ifcfg-eth0
echo HWADDR=$MAC >> /etc/sysconfig/network-scripts/ifcfg-eth0
echo IPADDR=$IP >> /etc/sysconfig/network-scripts/ifcfg-eth0
echo BOOTPROTO=none >> /etc/sysconfig/network-scripts/ifcfg-eth0
echo NETMASK=$NETMASK >> /etc/sysconfig/network-scripts/ifcfg-eth0
echo TYPE=Ethernet >> /etc/sysconfig/network-scripts/ifcfg-eth0
echo GATEWAY=$GATEWAY >> /etc/sysconfig/network-scripts/ifcfg-eth0
echo IPV6INIT=no >> /etc/sysconfig/network-scripts/ifcfg-eth0
echo ONBOOT=yes >> /etc/sysconfig/network-scripts/ifcfg-eth0
echo USERCTL=no >> /etc/sysconfig/network-scripts/ifcfg-eth0

#Restart Network Service
service network restart

Once networking is working the goal than is to get LED lights working as per viewtopic.php?f=2&t=2335

Right now I have this

[root@dnsserver leds-hpex47x]# ls
leds-hpex47x.c  leds-hpex47x.ko  leds-hpex47x.ko.unsigned  leds-hpex47x.mod.c  leds-hpex47x.mod.o  leds-hpex47x.o  Makefile  modules.order  Module.symvers

[root@dnsserver leds-hpex47x]# modinfo leds-hpex47x.ko
filename:       leds-hpex47x.ko
alias:          platform:hpex47x-led
license:        GPL
description:    HP MediaSmart Server EX47x HDD Bay LED Driver
author:         David Kuder <>
srcversion:     56767E3D3D0D2CC3829EC0F
vermagic:       2.6.32-358.2.1.el6.i686 SMP mod_unload modversions 686

[root@dnsserver leds-hpex47x]# insmod leds-hpex47x.ko

[root@dnsserver leds-hpex47x]# lsmod | grep leds
leds_hpex47x            1944  0

It appears that it SHOULD work hopefully.

So Far I have setup the boot drive on another pc and have CentOS all setup.

I'll let you know how my project goes once I get the unit.

I am YET to see anybody do a in-depth Linux install for this. I've only seen Ubuntu installs.

I'm a huge fan of CentOS which is RHEL which is stable IMO so this could be a first trying to get CentOS working on this :)
