Installing OpenManage Server Administrator on a PowerEdge 2900 w/Win2003 R2

I have a "virtual disk degraded" message when my PE 2900 boots up and I see one of 8 disks has a yellow LED instead of green. From my reading I need to install OpenManage Server Administrator to diagnose and solve/rebuild the drive. This server probably also need firmware updates. I probably have the original Dell CD's packed away but they are probably old and out of date (purchased 2008), so I want to just download Openmanage and install it.

My problem is when I look over the Dell downloads for that server there are so many possible downloads to choose from and none have good descriptions, so I don't know what to download and install. Does anyone else know what files would be up to date to install OpenManage?
