Actually it takes about 15 minutes, and it pretty much scrip-table. I
run Centos5.4 on 2 Dell r710's and 2 Dell r410s. Both have OMSA running
perfectly. I also had the run in with the Dell support techs about the
missing PERC drivers, and to be honest found them pretty clueless. They
seemed to me to have a script they were reading off. If your enquiry
fell outside the lines of the script, you are out of luck. Well, after
digging around for a while I found the required packages, and things are
perfectly good now. 
Its not that stuff it requires Red Hat, its that they, support from
Dell, dont know how to do it with anything else.

here's how I did it for r410s : 

	wget -q -O - http://linux.dell.com/repo/software/bootstrap.cgi | bash
	wget -q -O - http://linux.dell.com/repo/hardware/latest/bootstrap.cgi |
bash
	yum -y update
	yum -y install OpenIPMI srvadmin-all dell_ft_install lsb gcc
kernel-devel
	yum install $(bootstrap_firmware)
	update_firmware --yes
	/etc/init.d/ipmi start
	srvadmin-services.sh  start

        reboot

        tar -xzvf R211003-mptlinux-4.00.38.02-3.tar.gz
        rpm -Uvh dkms-2.0.19.1-1.noarch.rpm
        rpm -Uvh mptlinux-4.00.38.02-3dkms.noarch.rpm

        reboot.

and all done...The only package you need to 'find' is the mptlinux
tarball, and you can actually download that from the Dell site oddly
enough. There are also many other places you can download it. The order
matters, dkms first. Untaring the tarball gives you the other two rpms.

for the r710 it was a different package. It depends on the actual
hardware that Dell put into your machine. :

rpm -Uvh dkms-2.0.22.0-1.noarch.rpm
rpm -Uvh megaraid_sas-v00.00.04.17-2.noarch.rpm
/etc/init.d/ipmi restart
srvadmin-services.sh  restart

I got the RPMs here from Dag I think, but pbone of the other RPM repos
will have it too.


In the end though, these 64bit 24Gig 4xquad babies run OMSA perfectly,
and RAID and PERC reporting in correctly. I know that if Dell had had
their way they would have talked my boss into buying Red Hat, but I just
believed it wasn't necessary, and fortunately I had at that time no
life, so I was able to spend some time on it (wife was in nursing
school).

here is the output from dmesg regarding the PERC card :

Hope all this helps. Its not that I mind paying Red Hat, if my company
could afford to we would happily pay for the support. However as that is
not possible, I wanted to point out that Dell OMSA is perfectly doable
on CentOS :)
