The CentOS 5 operating system has the SAS1068 (SAS 5/iR) drivers already configured. For installing the OS, boot the server and:

	after the BIOS of the SAS controller is initialized hit Ctrl+C to enter the SAS configuration utility;

	from the “Adapter List” select your adapter, SAS1068;

	select “RAID Properties”. Delete existing virtual disk:

	select “View Existing Array”;

	select “Manage Virtual Disk”;

	select “Delete Virtual Disk”;

	press “Y” and then “F3″ to delete the virtual disk. Create a new virtual disk:

	select “Create IM Volume” for a mirrored raid or “Create IS Volume” for a striped raid. The latter has not been tested by me, but I suspect that it will work the same for both;

	add your disks to the RAID by selecting “YES” in the “RAID Disk” column. Dismiss any warnings about existing data on the disks;

	press “C”, then “Save changes then exit this menu” and then “F3″ to create the actual virtual disk;

	finally insert your CentOS 5 install cd and exit the configuration menu and reboot. Select the default options, erasing the entire disk. Start-up and update your system. Check the Os version with the command:

cat /etc/redhat-release

or

/usr/bin/lsb_release -a

or

rpm -qa | grep kernel

or

uname -r

Now you need to install the Dell OpenManage software. Login as administrator and copy on your server, from the Dell installation CD, the whole directory with all the subdirectories, then change the permissions of all the files of in rwx. Before starting, you have to install two necessary packages:

	Install SNMP agent (important to do this before installing OMSA)

yum install net-snmp net-snmp-utils

	Ensure necessary packages are installed

yum install ncurses libxml2 compat-libstdc++-33

The OpenManage installation will work just with RHEL or SUSE linux OS: one of the ways is to “bastardise” your CentOS distribution changing the content of the file /etc/redhat-release in:

Red Hat Enterprise Linux Server release 5 (Tikanga)

making a backup copy of the old file.

Navigate to the  directory and run the srvadmin-install.sh script as shown below

sh srvadmin-install.sh -x

Once installed OpenManage, start the Server Administrator services (which do not start automatically) by the command:

sh srvadmin-services.sh start

You can access OpenManage on your server entering the following web address in Firefox:

https:// :1311

eg: https://127.0.0.1:1311

or, from the net eg:

https://192.168.1.150:1311
