Before you can upgrade or reinstall a security server instance, you must remove the current IPsec rules that govern communication between the security server and its paired View Connection Server instance. If you do not take this step, the upgrade or reinstallation fails.
By default, communication between a security server and its paired View Connection Server instance is governed by IPsec rules. When you upgrade or reinstall the security server and pair it again with the View Connection Server instance, a new set of IPsec rules must be established. If the existing IPsec rules are not removed before you upgrade or reinstall, the pairing fails.
You must take this step when you upgrade or reinstall a security server and are using IPsec to protect communication between the security server and View Connection Server.
You can configure an initial security server pairing without using IPsec rules. Before you install the security server, you can open View Administrator and deselect the global setting Use IPSec for Security Server Connections, which is enabled by default. If IPsec rules are not in effect, you do not have to remove them before you upgrade or reinstall.
With View 5.0.x and earlier releases, you could remove a security server either from within the View Administrator user interface or by using the vdmadmin -S command-line command. In View 5.1 and later releases, you must use vdmadmin -S. See "Removing the Entry for a View Connection Server Instance or Security Server Using the -S Option" in the View Administration document.
