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


/usr/bin/lsb_release -a


rpm -qa | grep kernel


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 <srvadmin> with all the subdirectories, then change the permissions of all the files of <srvadmin> 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 <srvadmin/linux/supportscripts> 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:



or, from the net eg:
