Access Control
Access Control is a feature of Access Logix that connects the host system to
the storage system. Enabling
Access Control
prevents all host systems from
accessing any data on the storage system until they are given explicit access to
a LUN through a storage group. By installing Access Logix on your storage
system(s) and enabling
Access Control
, you can prevent the host systems
from taking ownership of all LUNs on the storage system and prevent
unauthorized access to sensitive information.
Access Control is enabled using Navisphere Manager. After you enable Access
Logix 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
in Navisphere Manager, you are
using Access Logix.
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 3-3 describes the properties in the storage group.
