When you use iManager to view user space quotas or directory quotas for a DST volume, the tools report only the quotas set on the primary volume.
The Storage plug-in in iManager is not aware of the DST relationship between the NSS volumes in a DST volume pair. You can use the Storage plug-in to view user space quotas set on NSS volumes. When you view user space quotas for the primary volume of a DST volume pair, the tool reports the usage for the primary volume only. It does not report user quotas set on the secondary volume, and it does not consider the user’s data on the secondary volume when it calculates quota usage.
The Files and Folders plug-in in iManager is not aware of the DST relationship between the NSS volumes in a DST volume pair. You can use the Files and Folders plug-in in iManager to view directory quotas set for directories on NSS volumes that are mounted in both NSS and NCP. Because the secondary volume is not mounted in NCP while it is in a DST volume pair, you cannot manage directory quotas on the secondary volume with this tool. When you view directory quotas for a directory on the primary volume of a DST volume pair, the Files and Folders Directory Quota option reports the usage for the primary volume only. It does not report the directory quotas set on the secondary volume, and it does not consider the directory’s data on the secondary volume when it calculates quota usage.
