Dell PowerStore Configuring Multiprotocol File Sharing

Change NAS server UNIX credential settings

1. Select Storage > NAS Servers.
2. Select the NAS server from the list and then select the Sharing Protocols tab.
3. Select the NFS Server tab.
4. Make the necessary changes, as described in the following table.

   Table 1. NAS server UNIX credential settingsColumn one lists the tasks for changing NAS server UNIX credential settings, column two describes how to perform each task.

   Task	Description
   Extend the UNIX credential to enable the storage system to obtain more than 16 group GIDs. NOTE:This is required only if you have users with more than 16 GIDs. NOTE:With secure NFS, the NAS server always builds the UNIX credential, so this option does not apply.	Enable or disable Extended Credentials. If this option is enabled, the NAS server uses the User ID (UID) to obtain the primary Group ID (GID) and all group GIDs to which it belongs. The NAS server obtains the GIDs from the local password file or UDS. If this option is disabled, the UNIX credential of the NFS request is directly extracted from the network information that is contained in the frame. This method has better performance, but it is limited to including up to only 16 group GIDs.
   Specify a UNIX credential cache retention period. This option can improve performance, because it reuses the UNIX credential from the cache instead of building it for each request.	In the Credential cache retention field, enter a time period (in minutes) for which access credentials are retained in the cache. Range is 1 - 35791394, default value is 15 minutes.
