Cannot create partition on 4TB span
Posted on 2010-09-03
I have a Dell PowerEdge 2950 that just had all six of the drive bays filled with 2TB drives. The Array configuration utility was run during the initial server installation using the Dell systems Management disk version 6.3.
The 6 drives were setup as a single RAID10 array. Once in Windows, the OS sees the array as two Disk0 one being 2TB and one being 4TB (actually a little less in both because of overhead). The OS was installed to a 100GB partition on the 2TB Disk0 and the rest configured as a single large partition. However, in Disk Management the 4TB Disk0 shows up, but no new partition can be created. All options are grayed out. OS is Windows Server 2008 x64 Standard. Dell OpenManage shows everything fine, but Windows seems to have a problem doing anything with the drive. I can't even select the option to convert to GPT disk.
How do I create a partition of partitions in this space? I'd hate to have wasted 8TB or raw drive capacity.
