I would certainly make sure the disk is healthy, but otherwise, you should be able to "import" the foreign configuration.  Only after importing the foreign configuration will your "disk" be available to the OS again.
Hello all. My client's PE 2900, with a PERC 6/i controller, shows a foreign configuration caused by a failed Physical Disk that is now indicated as Normal. This is a non-certified Enterprise single disk / RAID 0 and  SA Logs didn't show a predicted failure for this disk.  All of whats shown in the screen shot below occurred  in less than 40 seconds. [IMAGE] Since the disk is now showing as "returned to normal", does that mean the drive is good and the data accessible (X my fingers)?  Can I pull the disk and run WD or 3rd party diagnostics to verify the drive and then import the Foreign Configuration? Still learning, so any help, comments, suggestions or guidance is very much appreciated!!! Thanks. comregen   PERC6/i  Driver v. 2.24.00.32       Driver Version out of date.
