http://serverfault.com – We had an extended power outage (almost four hours); now I have a Dell PowerEdge 2850 server which is giving me this error (from a PERC 4e/DI) on boot up: All drives are listed in the PERC configuration menu: The failed drive does not show any indications of failure on the LEDs; the bottom appears to be green and the top is unlit. None of the disk drive LEDs are flashing. All drives are in one RAID5 array with 6 stripes of 64K in size. I do have one or two spare Dell PE2850s available for test. However, from what I've read, the Unresolved configuration mismatch... error would show up t (HowTos)
