Manager-of-Managers Environment

Configuring a Centralized Media Management Database

On the MoM, add one cell at a time to the CMMDB.

Prerequisites

• Data Protector Cell Managers in all cells have to have the same

 

version of Data Protector installed and running.

 

• Check that there are no backup, restore, or media management

 

sessions running on any of the cells to be added to the multi-cell

 

environment.

How to Configure

To configure the CMMDB in the MoM environment, two phases are

the CMMDB

required:

 

• Configuration of the CMMDB on the MoM Manager. See “Configuring

 

the CMMDB on the MoM Manager” on page 369.

 

• Configuration of the CMMDB on the client cell. See “Configuring the

 

CMMDB on the Client Cell” on page 370.

 

 

NOTE

Once you have configured the CMMDB and start using it, it is not

 

possible to split it back into local MMDBs. It is not recommended to

 

recover the old state of a MMDB. Instead, you should create a new

 

MMDB from scratch.

 

 

Configuring the CMMDB on the MoM Manager

Log on to the MoM Manager and perform the following steps:

1. Copy the following directory to a temporary location for safety reasons:

• On Windows: <Data_Protector_home>\db40\datafiles\mmdb

• On UNIX: /var/opt/omni/db40/datafiles/mmdb

2. Run the following command to merge the local MMDB into the

CMMDB:

• On Windows: <Data_Protector_home>\bin\omnidbutil -mergemmdb<Cell_Server_Hostname>

• On UNIX: /opt/omni/sbin/omnidbutil -mergemmdb <Cell_Server_Hostname>
