A storage administrator is using Unisphere for VMAX to provision storage to a virtual machine. This virtual
machine needs to share an RDM device which is already presented to another virtual machine. The
administrator is unable to select the existing RDM to present to the virtual machine.
What could be the cause?

A.
Volumes already presented as an RDM to other virtual machines are excluded from the available volumes
list

B.
Only available storage from datastores can be presented to virtual machines using Unisphere for VMAX

C.
No volumes are available and a new volume cannot be created

D.
Existing volumes can only be presented to physical hosts
