Access Control is enabled using Navisphere Manager. After you enable Access Control and connect to the storage system from a management station, Access Control appears in the Storage System Properties window of Navisphere Manager. After you enable Access Control, the host system can only read from and write to specific LUNs on the storage system. This organized group of LUNs and hosts is called a storage group. Storage Groups A storage group is a collection of one or more LUNs that are assigned to one or more host systems. Managed by Navisphere Manager, storage groups provide an organized method of assigning multiple LUNs to a host system. After you create LUNs on your storage system, you can assign the LUNs to a storage group in Navisphere Manager and then assign the storage group to a specific host. Because the host can only access its assigned storage group, it cannot access any LUNs assigned to other host systems, thereby protecting your data from unauthorized access. To create the storage groups for your host systems, you must use Navisphere Manager and enable Access Control in the storage system. NOTE: A host system can access only one storage group per storage system. Table 3-2 describes the properties in the storage group. 46 Preparing Your Systems for Clustering

Preparing Your Systems for Clustering
Access Control is enabled using Navisphere Manager. After you enable
Access
Control
and connect to the storage system from a management station,
Access Control
appears in the
Storage System Properties
window of
Navisphere Manager.
After you enable
Access Control
, the host system can only read from and
write to specific LUNs on the storage system. This organized group of LUNs
and hosts is called a
storage group
.
Storage Groups
A storage group is a collection of one or more LUNs that are assigned to one
or more host systems. Managed by Navisphere Manager, storage groups
provide an organized method of assigning multiple LUNs to a host system.
After you create LUNs on your storage system, you can assign the LUNs to a
storage group in Navisphere Manager and then assign the storage group to a
specific host. Because the host can only access its assigned storage group, it
cannot access any LUNs assigned to other host systems, thereby protecting
your data from unauthorized access.
To create the storage groups for your host systems, you must use Navisphere
Manager and enable
Access Control
in the storage system.
NOTE:
A host system can access only one storage group per storage system.
Table 3-2 describes the properties in the storage group.
