Hi FM_Kerckhof,   Raid migration from an H200 to a PERC6 is not supported and the PERC6 will not be able to see the virtual disks from the H200. The valid migration paths from an H200 to another internal controller are from H200 to H200 and H200 to H700. So the drives may or may not be damaged from the fire, them not being seen is not an indication either way.
Hi,  Due to a recent failure of an inline cooling unit the server room where my server was placed caught fire.Althought the rack of my server was not damaged, it took in a lot of ashes and dust. I am trying to clean it but for now I have exactly the same system (dell poweredge R410) but with a PERC 6i in stead of a H200A RAID controller card. I have 2 1TB nearline hot swap SAS drives that were configured in RAID0 in the initial system. However, booting fails as the PERC 6i does not recognize any virtual drives. In the configuration utility the two physical drives are detected without any errors however no virtual drives are detected and the 'foreign config' option is not selectable. Also with the individual drives the rebuild and the repalce or force online/offline are not available. Does this mean my hard drives are damaged? Does anybody have a suggestion what is the best way to recover the data? Any pointers are highly appreciated.  Kind regards,  Frederiek-Maarten Kerckhof
