Basic instructions can be found in the "Vbrick DME Checkup" guide.
The actual original "Content" drive of the DME should not be expanded. The two drives created by the DME OVA should remain at their default sizes.
To add additional space to a DME for content storage, additional drives should be added to the virtual machine, then provisioned in the DME Vbadmin. For information on adding additional disks to the virtual machine and provisioning this space, please see the Disk Status section of the
DME Admin Guide.
