Smart array controller Or hard disk Problem

[Emankhly]

In BL 460 G7 in enclosure C7000 . I have found problem saying no controller detected and can't read raid or ORCA by smart start no controller detected and the controller is built in system board by changing sys board from another one the problem still there , When moving the two hard in another working server it show the same message , so I think that the problem was in server , and any other hard in the x server the server working and don't show the message . and now I know that there is one of these hard is failure and I got it but can't rebuild with another one and give me message : the controller is disabled because of data loss . Press F1 to resume with keeping the array disabled Press F2 to accept data loss so what can I do ? If you have farther information that can help ..../..../
