Before setting directory quotas on an NSS volume, you must enable the Directory Quotas attribute for the volume. You can set the attribute at create time or at any time for an existing volume.
To set the Directory Quotas attribute for an existing volume:
In iManager, click Storage > Volumes.
Select a server to manage to view a list of NSS volumes on the server.
In the Volumes list, select a volume that you want manage.
Wait for the volume details to be displayed before you continue.
Click Properties.
The Properties page has three tabs: Attributes, Statistics, and Quota Usage. It opens to the Attributes tab.
On the Attributes tab, select or deselect the Directory Quotas check box, then click Apply.
If you enabled or disabled the Directory Quotas attribute, restart NCP2NSS by entering the following at a terminal console prompt:
/etc/init.d/ncp2nss restart
