HP Operations Manager

Server or cluster failover behavior


HPOM for Windows monitors the availability of server components such as the Windows Management Interface (WMI), the server itself, and the cluster resource group (if your environment contains clusters.)

In the event of a failure of one or more of these components, some activities may be temporarily unavailable, until WMI or the server is restored. Depending on the cause of the failure and your specific environment, you may experience different results depending on your activity at the time of the failure. Some activities may be interrupted, as described below. You will see a message explaining that a service or component is temporarily unavailable and you have the option to retry the action.

In a cluster environment, services should fail over to another server in the cluster so that you can continue to work almost without interruption.

Node Configuration Editor

If a failure occurs while you are bringing nodes under management, the following actions occur: You can continue to work in the console to perform the following tasks: However, you cannot apply your changes and close the editor until WMI or the server are available again.

Service Type Editor

If you are performing an operation that requires network access to the server at the time of a failure, you will see a message explaining that your changes will be lost. You can return to the Service Type dialog box or exit.

Tool Configuration Editor

If you are performing an operation that requires network access to the server at the time of a failure, you will see a message explaining that your changes will be lost. You can return to the Tool Configuration dialog box or exit.

Apply Tool dialog box

If you are in the process of running a tool when the server connection is lost, any tools that are currently running will stop. You will see a "server down" message in the Tool Output details pane and the Rerun button will be unavailable. When the server connection is restored, the Rerun button will again be available.

Policy management server

If you are working with the policy management service at the time of a failover, you must reconnect to the PMAD server manually. See the help topic Reconnect to the policy management server.
