First, the tiny LCD screen will most certainly tell you if a PSU is failing - it will go from the normal blue background to orange, and tell you which PSU. It will also say if the RAID controller is having problems. The disks themselves are another issue. Find and d/l MegaRaid, which will let you manage the RAID (I don't know which PERC this has - we have 4xx, 6xx, and 8xx servers) if it's a PERC 6 or 7, while the system is running, without having to reboot and use the firmware software. mark
