• Unallocate Storage button
• A list of the volumes that are in the storage pools of the user group selected in User Group, and meet

5. To further narrow down the volumes, use filtering. In the list of volumes, from the pull-down list for an
item, select the value that corresponds to the desired volumes. The volumes that meet the selected value
are selected from the displayed volumes.
6. Select the checkbox for the volume for which allocation is to be released.
Note that you can select a maximum of 200 volumes at any one time. If you want to select more than 200
volumes, select them in multiple operations. For example, if you want to select 240 volumes, select 200
volumes in one operation, and the remaining 40 in another operation. Also, if a volume is related to more
than one volume path, the total number of selectable volumes decreases according to the number of
related paths. For example, if every volume is related to two volume paths, the number of selectable
volumes decreases to approximately 100.
