Converting Virtual Volumes
Converting virtual volumes from one type of provisioning to another allows you to balance space
savings and cost. You can save storage space by converting little-used volumes to Thin volumes.
Costs can be reduced by converting fully allocated volumes to Full volumes. Volumes can remain
online and continue I/O operations during the conversion process.
To convert a virtual volume, access the Convert Virtual Volume wizard. This wizard allows you to
convert Thinly Provisioned volumes to Fully Provisioned and Fully Provisioned volumes to Thinly
provisioned.
The Convert Virtual Volume wizard is accessible through the In the Main Menu Bar (click Actions
> Performance > Edit Chart), through the Convert button on the Toolbar when viewing the virtual
volumes Summary tab, as a selection on the Toolbar under the Virtual Volume button when viewing
the Virtual Volumes tab, and through the Provisioning Manager as described below:
1.
In the Manager Pane, click Provisioning.
2. In the Management Tree, click Virtual Volumes under the system containing the volume(s) you
wish to convert.
3. Under the Virtual Volumes tab in the Management Window, right-click on the volume you
wish to convert and select Convert Virtual Volume.
The Convert Virtual Volume(s) dialog box appears.

2. Select the Domain, if any, of which the volume is a member.
3. (Required) Select the Conversion: Fully provisioned to Thin or Thin to Fully provisioned.
A list of all Fully or Thinly provisioned volumes, depending on the conversion you selected,
will appear in the Virtual Volumes groupbox.

5. (Required) In the CPG groupbox, select the Target CPG on which the conversion will be
performed. (The default is the original CPG.)
If you select <original CPG> to convert volumes that provision space from different CPGs, the
system converts each volume and retains the CPG currently used for each volume. If your
selection includes virtual volumes that do not currently provision space from a CPG, you must
select a CPG in order to continue. The system will convert and move all selected volumes to
the selected target CPG
6. Click OK to start the conversion.
A task of type Convert Virtual Volume will be created. See “Displaying Tasks” (page 347) for
