As per title. Basically what are Dell's online tools for checking or changing BIOS/RAID-controller level conf. For Linux.
The Dell suite is called "Open Manage". You have a lot of info here on their site. Basically on a rpm-based distro ( in my experience this works very well with rhel-based distros) you just have to do:
wget -q -O - http://linux.dell.com/repo/hardware/latest/bootstrap.cgi | bash yum install srvadmin-storage
( actually dell recommends srvadmin-all, but if you just want to manage your raid controller this is enough ).
Then you have to look at:
/etc/init.d/dataeng start => starts the services need omreport storage controller=0 => info about your controller omreport storage -? => help for getting info omconfig storage -? => help for configuring your card omreport storage vdisk controller=0 => status of virtual disks omconfig storage controller action=createvdisk ..... => create an array
CAVEAT: on some dell servers ( ie: PE1950 with bnxII nic drivers ), if dataeng starts before then xend service ( if your host is a dom0 xen server ), you will loose network connectivity!!!. If you have the problem take care to configure the dataeng service to start after the xend service.
edit: with srvadmin-all you will have various tool which will help you to update firmware, manage drac cards and many things. For Temp monitoring and so on you can do this with ipmi, without the dell packages ( you need however to install ipmi tools and drivers ).
The RAID controller stuff is the never-to-be-sufficiently-damned MegaCli; I don't recall off the top of my head what the BIOS management tool is, but I'd be surprised if it wasn't in the smbios toolset somewhere (I've used that tool to get/set the service tag; never had the need to fiddle with BIOS settings directly, though).
