You can use the Resize Quota dialog box in System Manager to adjust the active quotas in the specified volume so that they reflect the changes that you have made to a quota.
Before you begin
Quotas must be enabled for the volumes for which you want to resize quotas.
Steps
Click Storage > Quotas.
In the Quota Status on Volumes tab of the Quotas window, select one or more volumes for which you want to resize the quotas.
