I have an HP ProLiant ML350 running MS Windows 2003 R2. It has a LSI20320C-HP controller with 3-146GB drives attached. Drives 0 & 1 are configured RAID 1 and set as boot drive. Drive 2 is configured a a data drive no RAID. When I do a SHUTDOWN or REBOOT the OS will shut down then the lights on the drive C: will begin to blink at a repetitive rate in sync with each other and the third drive light is on solid. The display is lit with the pointer on it but is non reactive to any mouse movement. The system will sit there in that state for hours without ever shutting down. Any ideas as to what is not configured properly or is broken?
