Workaround for FOXMAN-UN Upgrade in Main/Standby Setup
This chapter describes a workaround for the limitation “Unable to pair servers after reinstallation without unpairing” described in the list of limitations provided with the FOXMAN-UN R18 release note.
Initial situation: Main server and Standby server are paired.
To upgrade the Standby server, the previous FOXMAN-UN version on the Standby server is uninstalled, and the FOXMAN-UN 18.0.0 is installed on the Standby server.
Also, Main/Standby functionality on the Standby server, i.e., periodic backup and configuration as cold or warm standby, is re-enabled. The described limitation describes the fact that while uninstalling, the existing pairing is broken.
Now when you connect to the Main server using the Remote Admin Tool (RAT), to configure the Partner server (i.e., the Standby server), you get an error message (“Communication to the remote server is broken”), and the RAT is closed.
To prevent this:
1. Open the RAT again but do not click on “Configure Partner Server...”, but click on “Main/Standby Configuration...”.
2. Acknowledge the error message.
3. In the Main/Standby Settings, select the Partner Server that is still configured by clicking on the respective table entry.
4. Click the “Unpair” command button and acknowledge the confirmation message.
• Click on “Cancel”.
5. Back in the RAT main window, click on “Main/Standby Configuration...” again.
6. In the Main/Standby Settings, click the “Pair...” command button.
• Log in to the remote (Standby) server by entering username, password, and host name and/or IP address, then click the “Pair” button.
7. Accept the SSL Certificate, then acknowledge the confirmation of successful pairing.
8. Click OK to conclude the Main/Standby settings.
Result: Servers are successfully paired again.
