    I have an issue with a Mac Pro set up with RAID 5 with 4 500GB drives with OSX Server 10.5

    The server boots and we receive the flashing Folder and ? icon. I boot into the OSX install disk and open the raid utility and it says that the RAID set is degraded. One of the disks says it is roaming, so I replaced it, the new disk now says the it is a JBOD. I tried using Terminal to adopt the disk but I get the message that the RAID controller is busy and cannot accept requests. Under status it says the RAID is suspended. It also looks like an initialization has started but has not completed (in fact it says 0%).So now for the questions:

    - Does this sound like a RAID controller issue?
    - Is it possible to restart/reset the RAID controller without losing the current RAID set and data to enable disk adoption?
    - If I replace the RAID controller, will I loose the current RAID set and data?
