Create an RDM Volume
You can create a volume, map it to a VMware virtual machine, and create a raw device mapping to the virtual machine in one
operation.

Manager determines that the VM is not powered on, the Create RDM Volume menu option is not displayed.
Steps
1. Click the Servers view.
2. Click the plus sign (+) next to the vSphere host, on which the virtual machine is located, to display the Virtual Machines
node.
3. Click the plus sign (+) next to the Virtual Machines node to display the virtual machine.
4. Select the virtual machine on which to create the datastore.
5. Click Create RDM Volume.
6. Enter a name for the volume in the Volume Name field.
7. Select the unit of storage from the drop-down menu and enter the size of the volume in the Total Space field.
8. Select the Storage Center on which to create the volume.
● To manually choose a Storage Center, select it from the Storage Center drop‑down menu.

options as needed, then click OK.
● To specify the name of the volume, type a name in the Name field.
● To specify the folder in which the volume will be created, select a folder from the Volume Folder area.
● To add notes to the volume, type notes in the Notes field.
● To schedule snapshot creation and expiration for the volume, apply one or more Snapshot Profiles by clicking Change

● If Chargeback is enabled, select the department to charge for storage costs associated with the volume by clicking
Change across from Chargeback Department.
