Recover Active Server

In certain circumstances, it may be necessary to forcibly make the Master or Replica server the active server without completing the data synchronization process. For example, if switchover occurred but no data was changed on the Replica server. In this case you may even have newer data on the Master server making it undesirable to synchronize data from the Replica to the Master server. Arcserve RHA allows for this option through a process called Recover Active Server.

To use the Recover Active Server option, stop the scenario, and then select Recover Active Server from the Tools menu.

Important! While this option is the right choice in many situations, use it with caution. If used improperly data loss can occur. Normally, Arcserve RHA will not allow switchover from one host to another until all data is synchronized. It is designed this way so users are not redirected to an out-of-date data set that then overwrites what may be a more current data set. When using Recover Active Server, Arcserve RHA is forcing users to one server or the other with no regard as to which server has the correct data set. Thus, as an administrator, you must manually ensure that the server you are making active has the most up to date data set.

If Recover Active Server does not solve the problem, you can manually recover a server. For more information, see Recovering Servers.

Select either Make Master Active or Make Replica Active, depending onto which server you want to force the active role.

Important! If a legitimate switchover occurs in a disaster situation and users are redirected to the Replica server for any period of time, it is important to replicate all changes on the Replica back to the Master before making the Master server active. Using Recover Active Server in such a situation results in loss of data.
