5. If you would like to select a storage pool from a folder, navigate to the folder in the tree on the
left of the screen. The Select Storage Pool(s) screen displays the list of storage pools in the selected
folder.
6. Select a storage pool from which you want to allocate more capacity to the virtual disk. The
storage pool must have some free space available.

want to deselect the storage pool, select the storage pool in the lower right area, and click
Remove.

allocate from the storage pool. You must allocate a value greater than 1 GB and not greater
than the free capacity of the storage pool, or 2 TB of total capacity, whichever is reached first.
The units of measurement are specified in the Units field in the next column. Adjust the units, if
necessary, by clicking the Units field and selecting a new value from the drop-down list.

Managing virtual disk permissions
The following virtual disk permissions operations are available:
• Add Host Permission—You can add permission for one or more hosts to access the virtual disk.
• Change Host Permission—You can change the type of permission assigned to a host that has
permission to access a virtual disk.
• Remove Host Permission—You can remove permission from a host that currently has permission
to access the virtual disk.
• Change LUN—If a virtual disk is set to allow permission only to UDH hosts, you can change the
LUN that the DPM uses to expose the virtual disk to the host.
These options are not available for a virtual disk that belongs to a virtual disk group or that has
components associated with it that were created by VSM services, such as the snapshot service.
Adding host permission
You can add host permission to a virtual disk that has no host permission defined or add permission
to an additional host for a virtual disk that already has host permission defined. This option is not
available for a virtual disk that belongs to a VDG or that has components associated with it that were
created by VSM services, such as the snapshot service.
To present one or more virtual disk(s) to a specific host:
1. In the navigation tree, expand the Entities node.
2. Click the Hosts node. The hosts list appears in the list area.
3. Right-click the host to which you want to present virtual disks.
4. Select Manage > Manage Virtual Disk Permission > Add Permissions. The Add Permissions wizard
opens to the Select Virtual Disk(s) screen and displays the list of available virtual disks.
