Dell PowerVault 775N (Rackmount NAS Appliance) - Manual (Page 63)

Access Logix allows multiple cluster nodes and servers to share a Dell | EMC storage system, restricts server access to
specific volumes on a shared Dell | EMC storage system, and protects your data from unauthorized access. Access Logix is
required when the storage system is connected to two or more clusters, two or more nonclustered systems, or a combination
of both clustered and nonclustered systems.
Using Access Logix, you can partition LUNs in a storage system into RAID groups, and then use storage groups to restrict LUN
access to the assigned hosts. Access Logix is installed on your Dell | EMC storage system when you update the core software
(firmware).
After you update the core software, you can enable Access Control. The default setting is set to Disabled. However, after you
enable Access Control, it cannot be disabled.
Access Logix is not required on all cluster configurations. Table 5-3 provides a list of cluster configurations and their Access
Logix requirement.

See your Dell | EMC storage system documentation for more information.
To enable Access Control and create storage groups:
1. Open a Web browser window.
2. Enter the IP address of the storage management server on your Dell | EMC storage system.
NOTE: The storage management server is usually one of the SPs on your storage system, but may also be a host
system running the Navisphere Management Server for Windows software.
3. In the Enterprise Storage window, click the Storage tab.
4. Right-click the icon of your storage system.
5. In the drop-down menu, click Properties.
6. In the Storage Systems Properties window, click the Storage Access tab.
If the Storage Access tab does not appear in the Storage Systems Properties window, Access Logix is not installed
on your system.
7. In the Data Access box, select the Access Control Enabled check box.
A dialog box appears, asking if you want to enable Access Control.
