HP Data Protector MOM Configuration and Troubleshooting Guide

Installing the Media Agent on the MoM server
The Disk Agent and Media Agent must be installed on the MoM server if you need to perform a
local backup.
If the MoM server does not have a Media Agent installed, you cannot change such things as pool
settings using the Data Protector GUI. When you click Apply to save the changed pool name, a
dialog box is shown which does not let you change the properties:
The easiest solution is to install a Media Agent on the MoM server, but if you do not want to do
this, use the following workaround:
1. Find the configuration for the drives:
omnidownload -list_devices -detail > devices.txt
2. Modify the file to contain only the changes to the target drives.
3. Make sure you add the new pool names for the drives.
4. Make sure all GUIs are closed.
5. Apply the configuration:
omniupload -modify_device drive_name -file devices.txt
This process can be scripted for environments where many drives are present. Also libraries can
be re-configured by the –modify_library option of omniupload.
Restarting the Data Protector services in MoM
After you have configured the MoM environment, you are requested to restart the Data Protector
services.
If you use the Windows Service Control Manager to stop and start services on the Cell Manager,
only the current and previous copies of the database log are kept.
Use the omnisv command to save all previous database logs. The command is located in:
On Windows: Data_Protector_home\bin
On UNIX: /opt/omni/sbin/
Stopping Data Protector services
Cell Manager in a non-cluster environment
Run the following command: omnisv -stop.
Cell Manager on MC/ServiceGuard
Run the following command: cmhaltpkg pkg_name, where pkg_name is the name of the Data
Protector cluster package.
This stops Data Protector and dismounts the Data Protector shared volume group.
Cell Manager on Microsoft Cluster Server
Take the OBVS_VELOCIS cluster group offline (using the Cluster Administrator utility on the active
node).
You also need to stop the RS cluster service need to be stopped as well, and stop the Data
Protector inet service via local services.
