I want to check the RAID Configuration of several windows 2003 servers.  I know I can go into the BIOS during boot or RAID controller during boot but I want to to this on the OS level.  Does anyone know of any apps to determine the RAID config

Most raid controllers include a software utility to install on your OS. And with that tool you can check the array's status and usually you can also initiate rebuilds etc. Check the raid controller's manufacturer's site for downloads.

Many such utils also allow you to monitor the arrays from a central PC on your LAN, the array controllers just need to be compatible with that utility.

If you have HP kit, there is normally the Storage Array Configuration Utility that is installed as part of the default HP Proliant Support pack in Windows, etc.  Similar functionality exists from the vendors.

Why need another utility if you already have one?

I dont think there is tool that you can monitor the servers which you said they are different ones! Use what comes with each system as noted above.

You can get some rudimenatry info out of windows. My computer - properties - device manager. Under disk drives you will see the virtual (logical) drives configured on the RAID controller. It will usually say raid 1 or raid 5 or whatever. Select the drive - right click - properties and go to the volumes tab. Select populate and you will see the logical name (E: drive etc) and size.

RAID1 uses two drives so any more in the system must be the other drive. If RAID 5 it suggests a minimum of 3 drives. If you still have more physical discs but no more logical discs then they are probably part of the RAID5. If you have another logical drive it could either be a standalone JBOD (Just a Bunch Of Discs) or a hot standby for the RAID5.

If the person who built the system was techo then highly likely disc0 and disc1 are the RAID 1. You can probably tell which ones they are by search for something on the C drive, anything to exercise the discs. Two drive lights should blink pretty much together. Same this for drive E: (or whatever). The rest of the drives should be the RAID5 so all the rest of the lights should blink similarly. If the last one doesn't blink and you only have two drives then it's a good chance it's a hot standby. All of the drives could be one array as well in which case all lights should flash. Or variations, but you get the drift.

If you really can't reboot and use the BIOS tools this might give you enough info to make a judgement call about what's probably there. Of course this is checking the configuration - not the condition - of the arrays. For that you will need the management tool.

There are only the manufacturer's tools. Most of them do have reporting facilities, so if you setup a PC with something like OpenNMS or Nagios, you can monitor the status of your arrays, but also of other things.
