The customer has something like pseudoGEO cluster.<br/> He has 2 site with 1 disk array and 2node cluster in each.<br/> There is array replication between the arrays in two sites.<br/> Only one array is write enable at the same time the second one is read only.<br/> When he moves cluster from site A to site B he has to do it manually.<br/> It means change replication direction and take cluster resources offline on one site and take them online on<br/> the second site.So clusters works on the same disks, which are replicated by array replication.MPIO is installed on all the hosts.<br/> <br/> 1.msinfo32.exe output doesnot show any information about the partition. Rather it says partition information is not available.<br/> 2. My sample application to get drive details using the IOCTL_GET_DRIVE_LAYOUT_EX fails with ERROR_BUSY.<br/> <br/> The above failures happens for all the cluster disk resources in all the hosts.<br/> <br/>© 2009 Microsoft Corporation.
