An important customer has 2 metrocluster systems, or 4 controllers.
Each controller has a SAS volume that are presented to VMWARe 4.1 by NFS. Then, this volumes become datastores.
From these datastores, the vmware administrator created several virtual disks to a Windows Virtual Machine.
In the Windows Server, the administrator created a dynamic disk using the virtual disks from the 4 filers. I mean that each part of that dynamic disk are located into diferent datastores (Diferent controllers);
IS it supported? Does anyone have ever seen that?
There is a message on windows Device Manager. Those dynamic disks are at Health (At risk) state ( Indicates that the dynamic volume is currently accessible, but I/O errors have been detected on the underlying dynamic disk. If an I/O error is detected on any part of a dynamic disk, all volumes on the disk display the Healthy (At Risk) status and a warning icon appears on the volume.)
They have to use NFS (10GB) and dynamic disks, because "vmdk" disks are 2 TB max and they dynamic disks has 20TB.
