We have a Dell PowerEdge 2950 running Windows 2003 Storage server with 4 X 500GB drives in a RAID 5 configuration. I've added two additional 500GB drives to the RAID using the Dell OpenManage Server Administrator and can see that the additional space has been added to the array. However, in Disk Management I see two unallocated partitions and cannot figure out how to add them the existing partition. I thought I would need to convert the disk from Basic to Dynamic, but that option is grayed out. Any help would be appreciated.
