HP StorageWorks EBS with HP OpenView Storage Data Protector V5.1 Implementation Guide (October 2003)

Introduction
15EBS with HP OpenView Storage Data Protector v5.1 Implementation Guide
Manager-of-Managers
Data Protector provides the Manager-of-Managers (MoM) for management of
large environments with multiple cells. The MoM allows you to group multiple
cells into a larger unit, which can be managed from a single point. New cells can
be added, or existing cells can be split. MoM provides:
■ Centralized licensing repository—This optional feature enables simplified
licensing management.
■ Centralized Media Management Database (CMMDB)—The CMMDB
allows you to share devices and media across several cells in a MoM
environment. Using CMMDB, devices in one cell are accessible to other cells
that use the CMMDB.
— With the CMMDB, you can share high-end devices between cells in the
multi-cell environment. Once cell can control the robotics, serving several
devices that are connected to systems in different cells. EVen the Disk
Agent to Media Agent data path can go across cell boundaries.
■ Enterprise reporting—The MoM can generate reports on a single-cell basis
as well as for the entire enterprise environment.
EBS-Specific Requirements
EBS with Data Protector requires the Media Agent be installed on all clients that
have access to SAN shared tape devices. One server must have the Cell Manager
software installed while all other servers only require the Media Agent.
Shared Library and Tape Devices with Multiple Systems
Data Protector allows libraries and individual tape drives to be dynamically shared
between multiple Data Protector clients that run the Media Agent. Each server can
access any of the shared drives as needed and each server “owns” the drive it has
active. Shared drives are allocated in Data Protector Backup Specifications.
Shared drives must be configured with Device Locking to prevent two Data
Protector Media Agents from accessing the same physical device at the same
time. See the HP OpenView Storage Data Protector Administrator's Guide for
more information on configuring Device Locking.
Data Protector provides the Device Auto Configuration Wizard to make
configuring shared libraries and drives fast and easy. Using the wizard helps to
eliminate mistakes that are made when shared devices are manually configured.
