The relationship between the management server (the primary server) and the managed node is extended to other servers that will have responsibility for the node in the event of a primary server failure. The backup server should be installed following the standard OpenView Management server procedure.

In larger environments, multiple management servers become essential. The advantages include minimized use of network bandwidth for message transmission between the agents and servers, configuration of nodes within a specific region to report to a regional server, message forwarding and configuration control between multiple servers.

OpenView Failover Concepts

If a failover or takeover becomes necessary it means that the primary server where the node normally sends its messages is no longer available to receive information from its managed nodes. A surrogate server must assume responsibility for the nodes. When the primary server is available, it must resume responsibility for the managed nodes. Therefore, both servers including the primary and all secondary servers must maintain consistent configurations to minimize the time it takes to failover and failback.

1. Configure the management responsibilities (authorization) file called allnodes. Next, install and configure the backup server. Distribution of the all nodes file is final step prior to testing the setup.

2. Download the configuration data. In the GUI, select Action→Server→Download Configuration.

3. Install the backup server.

4. Distribute the downloaded configuration data to the backup server with the command opcmgrdist.

5. Stop all services on the backup server with ovstop opc.

6. Upload the configuration data to the backup server with the command opccfgupld.

7. Start the services on the backup server with ovstart opc.

8. Distribute the allnodes file and test the backup server. Switch to the backup server using the command on the backup server, opcragt –primmgr <node_name>.

Old News ;-)

Switch management server from OMW to HPOM in case OMW failure


I am having two management server architecture and out of which Operation Manager for Unix acts as Manager of Managers which receives alerts from OMW, NNM, BAC etc. and other management server is OMW which monitors servers and applications.

I want to forward all alerts to HPOM from OMW in case OMW services goes down or OMW server is not available.

Solution -
To achieve above target, perform following actions -

(1) Create a failover policy in OMW.
Failover policy would of type Flexible Management Policy with following content -

# Configuration file
# defines two action-allow managers
# messages are always send to the primary manager
DESCRIPTION "responsible mgrs for Nodes in VAA"
#Secondary managers have to be specified,
#but this section is not used by OpenView Operations for Windows
DESCRIPTION "HP OpenView Operation for Unix Management Server"
DESCRIPTION "HP OpenView Opearion for Windows Management Server"
DESCRIPTION "HP OpenView Operation for Unix Management Server"
DESCRIPTION "HP OpenView Opearion for Windows Management Server"
# Recommended: include the primary manager into the list of action-allow managers
# even if all possible managers are already listed
DESCRIPTION "current primary manager"
DESCRIPTION "always send all messages to current primary manager"

(2) Deploy the policy on all of the managed nodes

(3) When you want to switch management server from OMW to HPOM , run following command on HPOM server :
opcragt -primmgr

Wait till the command execution completes and check whether command is executed succesfully. If it goes successful then management server switching is done.

(4) If you want to revert the management server back to OMW then issue the same command on OMW server :
opcragt -primmgr
