Recovering configuration of RAID 5

    Question

  • Hi

    Is it possible to recover the configuration of the RAID 5 lost after a non successful formating .The OS is Windows Server 2008 R2.

    I want to recover my data on disk but I need to recover that configuration before.

    Thx in advance

    Regards

  • Hi,

    When a member of a mirrored or RAID-5 volume fails, it becomes an orphan. The operating system determines that it can no longer be used and directs reading and writing all new data to the remaining members of the fault-tolerant volume.

    When a member of a RAID-5 volume fails, you can reconstruct the data for the failed member from the remaining members. In Disk Management, select a new area of free space that is the same size as or larger than the other members of the RAID-5 volume, and then regenerate the data. If you are required to restart the computer, the volume manager reads the information from the stripes on the other member disks and then reconstructs the data of the missing member and writes it to the new member.

    To regenerate a RAID-5 volume, the volume must be locked by the operating system. All network connections to the volume are lost when a volume is regenerated.

    I’m not sure about the configuration of RAID 5 volume. You mean the RAID controller configuration? I think you’d better ask your question in the File Services and Storage Forum:

  • Hi

    Thanks James for the answer and for your time.

    In fact the real state of the server is no operating system and the  RAID controller configuration is lost totally so there's no disk manager
