OK I solved it On a shell I can use the command omreport and its help to know various details Or i can use a web interface on the server itself by connecting to [URL] and providing root password
I've downloaded and installed Open Manage administrator on a PowerEdge T110 server running RedHat I wasn't able to find instructions about how to use locally on the server the utilities OMSA installed. I've found the OM IT Assistant to be installed on windows, but i would like to know if i can use any console command in RedHat to know the RAID set status locally, not via web from a windows workstation Where can i find documentation about the commands and services installed and how to use them?
