Replacing a missing raid 5 disc
I have a dell poweredge 2900. There is a perc5 controller with a raid 5 configured. The raid consists of 4 hard drives. The operating system on the machine is windows 7. One hard drive (slot 2) has gone out and the raid is running on 3 drives. When i go in the BIOS configuration utility it shows discs 0,1,3 and where drive 2 is it says "missing". This is shown when I click on physical discs under the virtual disc. I can see the new drive in the BIOS where it says "controller" above the virtual disc selection but i dont know how to assign it back to the the physical disc slot where its "missing". Is it something i can even do in the Integrated BIOS configuration utility settings or do i need raid software in windows to get the raid to accept the replaced drive and rebuild? When i put windows 7 on, i never installed any dell raid software. I simply built the raid in the BIOS utility. Please let me know!!!

The Dell management software (OpenManage Server Administrator) will not run on Windows 7. You would have to try the less fully-featured management software designed for Windows 7 on Precision workstations (RAID Storage Manager) or LSI's generic software (may not work on Dell-branded LSI controllers).
To assign a new disk into an array, it must first be showing as READY (not Foreign) ... you need to assign it as a hot-spare. Did you replace the failed disk 2 or did you simply add a new disk in another slot? If/when you replace a failed hot-swappable disk, NEVER shut the system down to do it - always replace it "hot".
