    The customer has something like pseudoGEO cluster.
    He has 2 site with 1 disk array and 2node cluster in each.
    There is array replication between the arrays in two sites.
    Only one array is write enable at the same time the second one is read only.
    When he moves cluster from site A to site B he has to do it manually.
    It means change replication direction and take cluster resources offline on one site and take them online on
    the second site.So clusters works on the same disks, which are replicated by array replication.MPIO is installed on all the hosts.

    1.msinfo32.exe output doesnot show any information about the partition. Rather it says partition information is not available.
    2. My sample application to get drive details using the IOCTL_GET_DRIVE_LAYOUT_EX fails with ERROR_BUSY.

    The above failures happens for all the cluster disk resources in all the hosts.
