Failover and failback operations typically require between five to 20 minutes, depending on
the system configuration. During these periods, no Headquarter server services are
available. Failover and failback operation effects are resolved after the operations are
complete and the secondary (for failover) or primary (failback) server is functioning as the
Headquarters server.
Failover and failback operation effects on Call Manager include:
• Users configured on the Headquarters server lose most connectivity capabilities,
including telephony and video. IM connectivity is not affected.
• Users configured on distributed servers maintain all connectivity capabilities.
• Configuration changes are unavailable.
• Users logging into Call Manager while the secondary server controls the system must
specify the IP Address of the secondary server.
Refer to the Call Manager User’s Manual for instructions on specifying the server IP
address.
Failover and failback operation effects on voicemail include:
• Sites that receive voicemail through the Headquarters server lose voicemail access.
• Mailboxes lose access to any voicemail that is routed through the Headquarters server.
• Sites that receive voicemail from distributed servers retain voicemail access.
Failover and failback operation effects on other system components include:
• Account Code and Workgroup services are not available.
• Director, Web Client, and Call Manager configuration changes are not available.
• If DRS is enabled, intersite calls are unavailable to users residing on sites whose only
access to a DRS server is through the Headquarters server.
System Failover Conditions
After the failover operation is complete, the secondary server performs all distributed
server and application connectivity activities managed by the Headquarters server.
System Failback Conditions
After the failback operation is complete, the primary server resumes all distributed server
and application connectivity activities managed by the Headquarters server.
Implementation
Server Address Configuration
The primary and secondary IP addresses are configured on the Edit Server panel for the
Headquarters server, as shown in Figure 33. To access the Edit Server panel, open the
Application Servers List by selecting Administration -> Application Servers from the Main
Menu, then select the Headquarters Server on the list. On the Edit Server panel, the Host IP
Address parameter configures the Primary IP address.
