The repository, as well as instructions, are here.
The OMSA RPMs are in the hardware repository.
Briefly, to use the repository to install OMSA, you need only run two commands:
wget -q -O - http://linux.dell.com/repo/hardware/bootstrap.cgi | bash
- yum install srvadmin-all
To start all installed services without a reboot, enter the following command: srvadmin-services.sh start
Connect to OMSA by pointing a browser to https://<server>:1311.
If OMSA doesn't start the ipmi service then you can try:
[root@backup ~]# modprobe ipmi_si [root@backup ~]# modprobe ipmi_devintf [root@backup ~]# srvadmin-services.sh start
