HP Data Protector MOM Configuration and Troubleshooting Guide

Example
Each of the three departments at New York must be configured into a MoM cell. Additionally,
both London and Paris should be configured into local MoM cells, each with two Data Protector
client cells.
Configure cell A as the MoM cell for the New York environment, cell D as the MoM cell for the
Paris environment, and cell F as the MoM cell for the London environment.
The Cell Managers and Manager-of-Managers in all seven cells should be Windows systems. Use
a CMMDB in one of the cells in each MoM environment and Catalog Databases in each of the
seven cells. The CMMDB allows you to share libraries between cells within each MoM
environment.
Each of the three locations should have its own library.
The two cells at the Paris MoM environment should share a CMMDB, configured on the MoM of
cell D to enable the library to be shared between the cells.
Similarly, the two London cells should share a CMMDB, configured on the MoM of cell F to
enable the library to be shared.
In this way, each of the three MoM environments can use its own library, shared by client systems
in all cells in the environment. Using only one very large library for all data would not make much
sense, because huge amounts of data would need to be transferred over the WAN for backup
purposes.
The CMMDB is the result of merging MMDBs from several cells in the MoM environment. It allows
you to share high-end devices and media across multiple cells in a MoM environment. One cell
can control the robotics, serving the devices that are connected to systems in other cells. The
CMMDB must reside on the MoM. A reliable network connection between the MoM cell and the
other Data Protector cells is highly recommended.
