RAID 5 array degraded on DELL Poweredge T310

I have a DELL Poweredge T310 with a RAID 5 array in it (3 physical drives) running windows 2008 R2.  When I reboot and watch the screen as it boots, it says that the virtual disk is degraded.  However, I took the front chassis off, and it looks like all 3 drives have green lights.   The 3rd drive, however, is not blinking with the first 2.  Is there anything I can do, to get the array back up to a optimal state.

Thank you very much!

Do you have the Dell Array Manager (can't remember the exact name) program installed on the server?
You should be able to check the RAID status and see what it is.  If it is rebuilding then just wait some time and check it again.

Use the openmanage utility to check the state of the array (or check via the Controller's BIOS). depending on what you see there you will maybe have to replace a disk, or wait until the array has finished rebuilding.

You will need to go into the Raid Controller's configuration during bootup you can work with the Raid from here to see if you can get back online

RAID 5 degraded means one of your disk has failed.
from windows run openmanage and check the status.

if you do not have openmanage...
at the boot you will get to get in the RAID card configuration where you can check the status
try  ctrl + m, (or what it shows during bootuo) have you check from View from NVRAM and View from Disk?

..& some time shutting down the server (in case u didn't try) and back on you may not get 'virtual disk is degraded.' message.
