How to install OMSA to RHEL5 via yum

[Sever *]

Good day!

Can I somehow use the yum repository to install OMSA to my RHEL5 (it
works perfectly on servers where it has been installed earlier before
repo replacement)?

I did the following:

wget -q -O - http://linux.dell.com/repo/hardware/bootstrap.cgi | bash

But

# yum search srvadmin
Loading "dellsysidplugin" plugin
Loading "installonlyn" plugin
Loading "rhnplugin" plugin
This system is not registered with RHN.
RHN support will be disabled.
Setting up repositories
Reading repository metadata in from local files
No Matches found

The repos
dell-hw-indep-repository.repo
dell-hw-specific-repository.repo

were set.

Can You please help me?
