I know that when i ran the install on some of our centos machines that the storage component failed to install, but i cant remember what the error message was.
If you connect to the OpenManage GUI on the server your having issues with do you see any errors? im currently seeing issues with incorrect firmware/Driver on the Controller (PERC 6/i Intergrated) and im looking into getting the updated drivers installed but havent been able to give it much time yet.
there's no error at all in gui.
but the first time i installed using yum (all) there was some error about storage and can't see any storage devices in gui.
then i uninstall the whole thing out and install again, this time not us all, but install base, webserver, storage service(in that order) this time there was no error but still can't see storage devices.
