Component authorization

A storage group is an access control mechanism for LUNs. It segregates groups of LUNs from access by specific hosts. When you configure a storage group, you identify a set of LUNs that will be used by only one or more hosts. The storage system then enforces access to the LUNs from the host. The LUNs are presented only to the hosts in the storage group, and the hosts can see only the LUNs in the group (LUN masking). To configure a storage group, select your system and then use Host > Storage Groups. For more information on configuring a storage group, refer to the Unisphere online help.

IP filtering adds another layer of security by allowing administrators and security administrators to configure the storage system to restrict administration access to specified IP addresses. These settings can be applied to the local storage system or to the entire domain of storage systems. See Secure serviceability settings (block) for more details about IP filtering.
