HP XP Command View Advanced Edition Software - Manual (Page 16)

Overview of Command View XP Advanced Edition Device Manager 16
• Snapshot XP: The Snapshot XP feature (for StorageWorks XP12000/XP10000 only) allows the user to
make backup copies of volumes in the same storage subsystem. For details on Snapshot XP, refer to the
HP StorageWorks Snapshot XP User Guide.
• Storage group: A user-defined set of paths (LUNs) which can be manipulated as a group. Adding storage
to an empty logical group renders that group a storage group. The LUNs in the same storage group must
physically reside in the same storage subsystem. A storage group cannot contain another storage group
or logical group. Storage groups are displayed under the Logical Groups object.
• Subsystems object: A display of the physical configuration information for the storage subsystems, such
as: serial number, number and type(s) of ports, location and capacity of installed array groups, LDEVs
and paths, and amount of cache memory.
• User group: A user-defined set of users which can be manipulated as a group. Users in a user group can
only see and manage the logical groups, hosts, and volumes which are assigned to that user group. User
groups are displayed on the User Group Administration panel (restricted to system and local
administrators).
• Volume path/LUN: A path to an LU (volume) in a storage subsystem which maps the LU to a port and LU
number (LUN). Each LU can have one or more paths, and each path can have different LUN security
settings. The type of host platform determines the number of logical units (LUs) that may be connected to
each port.
• The StorageWorks XP12000/XP10000 supports up to 1,024 paths per fibre channel port.
• The StorageWorks XP1024/XP128 supports up to 512 paths per fibre channel port.
• The StorageWorks XP512/XP48 supports up to 256 paths per fibre channel port.
• V-VOL: Logical duplicated volume of the Snapshot XP function consisting of physical data stored in the
primary volume and differential data stored in the Data Pool.
• WWN group: A WWN group on a StorageWorks XP512/XP48. Device Manager allows the user to
manage WWN groups.
Table 1-1 shows some of these Device Manager terms and the corresponding terms used on the storage
subsystems.
