By default, nodes send
messages to the management
server that you used to install the agent. This is called the
primary management server. If you want to switch the primary
management server after you install the agent, you launch a
tool on the
new management server. After you do this, the nodes send their
messages to the new primary management server.
NOTE:
It is also possible to configure a different primary management
server in the agent installation defaults, but you must do this
before you install the agent.
You may want to prepare to switch primary management servers in
a backup scenario. For example, you could configure a second
management server to monitor the health of a primary management
server. If the second management server detects a system failure at
the primary management server, an administrator could then switch
primary management responsibility to the second management server.
The second management server would assume control of all the
managed nodes previously managed by the failed management
server.
Before you can switch primary management servers, you must
configure the following prerequisites:
Exchange node configuration between the management servers. The
new primary management server must exists as a node on the current
primary management server. The nodes for which you want to switch
the management server must exist on both management servers. (See
Exchange node
configurations.)
Configure the new primary management server as a secondary
management server of the nodes. You do this by deploying a flexible
management policy to the nodes from the current primary management
server. (See Configure
action-allowed and secondary managers.)
In addition, if the primary management server is currently an
HPOM for UNIX management server, you must consider the following
prerequisites:
If the HPOM for UNIX management server deployed the agent
package to the node, the agent package version must be 8.51 or
higher. (You cannot switch the primary management server if the
HPOM for UNIX management server deployed a lower version of the
agent package. This restriction includes all DCE agents.)
You cannot manage some HPOM for UNIX templates from an HPOM for
Windows management server. Similarly, you cannot manage some HPOM
for Windows policies from an HPOM for UNIX management server.
Consider removing or disabling these types of templates and
policies before you switch the primary management server. (See
Configuration
interoperability.)
To switch the primary management server
Open a console connected to the new primary management
server.
In the console tree, expand ToolsHP Operations Manager Tools.
In the details pane, double-click Switch Management
Server. The Parameters page opens.
Select the nodes that you want to switch to this management
server. Click Next. The Login page opens.
Optional. Type a User Name and Password.
The user must be a member of the HPOM administrators group. If you
leave the User Name and Password blank, the tool starts with the
credentials that you are currently logged in to Windows with.
Click Launch.... The Tool Status dialog opens, which
updates when the tool succeeds or fails.
TIP:
You can also use the opcragt command-line tool to
switch the primary management server on all selected nodes. For
more details, see opcragt.
