Table 2-1 Device Manager User Roles
User Role Description
Storage Administrator Configures and manages storage subsystems.
Can access all Device Manager functions and resources, but cannot configure user
accounts.
Guest Can view all Device Manager resources.
Local System Administrator Manages user accounts within a user group. Also performs operations on the users in the
user group.
Can use all Device Manager functions to access the resources assigned to the user group.
The physical information of a storage subsystem is not assigned to the user-defined user
group. Therefore, a user whose role is local system administrator cannot add or remove a
storage subsystem, perform operations in a physical view display or alert screen, or view a
report.
Local Storage Administrator Can use Device Manager functions, except for configuring user accounts, to access the
resources assigned to the user group.
Like local system administrator, a user whose role is local storage administrator cannot add
or remove a storage subsystem, perform operations in a physical view display or alert, or
view a report.
Local Guest Can view only the resources assigned to the user group.
Peer Reserved for use by the Device Manager agent only.
NOTE: Device Manager users with the authority to administer other users cannot give other users greater
authority than their own level of authority.
2-2 Storage Management Operations
Device Manager allows you to perform storage management operations for storage on subsystems added to
Device Manager.
• Storage Groups. Device Manager allows you to create and manage groups of LUNs (volume paths). The
LUNs assigned to a storage group can be manipulated as a group. Storage groups must contain logical
devices from the same storage subsystem. A storage group can contain only LUNs, not other groups.
• Logical Groups. Device Manager allows you to create and manage one or more storage groups under a
logical group. A logical group can contain storage groups containing LUNs or additional logical groups.
This additional level of grouping creates a file-system approach to storage management and allows you
to tailor your Device Manager system to your operational environment.
• User Groups. Device Manager allows you to create and manage one or more user groups. Each user
group is associated with one or more logical groups, hosts, and LDEVs, which will be visible to the users
in the user group. When you add a new user and specify a user-defined user group for the new user, this
user will only be able to access the resources (logical groups, hosts, LDEVs) associated with that user
group.
2-3 Configuration Operations
Device Manager allows you to view and manage the configuration of StorageWorks XP Disk Array storage
subsystems from a web browser.
Device Manager provides the following functions for all supported storage subsystems:
• Storage Subsystem Discovery. When you add a storage subsystem to Device Manager, the Device
Manager server discovers the storage subsystem on the Device Manager system network and
determines its identity and configuration.
• Configuration Display. Device Manager displays detailed configuration information for each storage
subsystem added, including: logical volume and physical disk drive information, array groups, RAID
levels, ports, cache memory, microcode levels, and other storage subsystem-specific information, such
as number and type of back-end array processors (ACPs) for StorageWorks XP1024/XP128 and
XP512/XP48.
• LUN scan. The LUN scan operation (see section 8-3 ) examines all LUNs on the storage subsystem and
automatically creates a hierarchy of logical groups and storage groups organized by port to contain all of
the existing LUNs on the storage subsystem. When you perform a LUN Scan, a logical group is created
