27. Use the checkboxes to set one DPM in the DPM group as primary and one DPM as secondary.
NOTE:
• Use care in selecting the primary and secondary DPMs to prevent over subscribing one
and under utilizing the other.
• If you click Finish without defining the primary and secondary DPMs, VSM defines these
roles automatically.
28. Click Next. The Select folder screen appears.
29. If you want to add the virtual disk to a folder, enter the folder name in the Folder field or click
Browse to browse to the folder. The folder must already be created. For information about creating
folders, see “Creating folders” on page 317.
30. Click Next. A confirmation screen appears.
31. Click Finish. The new virtual disk is created and is displayed in the virtual disks list.
Renaming virtual disks
You can rename a virtual disk if no hosts are currently assigned permission to access the virtual disk.
To rename a virtual disk:
1. In the navigation tree, expand the Entities node.
2. Click the Virtual Disk node. The virtual disks list appears in the list area.
3. Right-click the virtual disk you want to rename.
4. Select Manage > Rename. The Rename wizard opens to the New name screen.
5. In the New name field, enter the new name.
6. Click Next. A confirmation screen appears.
7. Click Finish. The virtual disk is renamed.
Converting virtual disks to thin provisioned virtual disks
Some regular (or “thick”) virtual disks can be converted to a thin provisioned virtual disk. A virtual
disk can only be converted to a thin provisioned virtual disk if the virtual disk:
• Is not presented to any host, including hosts that are offline.
• Has no PiTs (for example, is not part of an asynchronous mirror group).
• Does not belong to a virtual disk group.
• Is not part of a synchronous mirror group.
The thin provisioned virtual disk uses the same storage pool that the original virtual disk used before
the conversion. The thin provisioned virtual disk has an initial allocated capacity equal to the capacity
of the original virtual disk, and has the ability to expand to a larger, user-defined capacity. The
operating system must support the ability to recognize the larger user-defined capacity or there is no
value in performing this operation.
