Upgrading a Single-Site System With Two Servers 219
Supported on:
■ Single-site systems with four servers
■ Multi-site systems that include servers at regional offices and
servers at branch offices that use global or local IP Messaging
■ A pair of Global Voicemail Central Servers (GVCS) to enable Global
Voicemail Integration on an entire IP Messaging system
A GVCS coordinates mailbox creation and mailbox updates on
regional and branch office IP Messaging servers. If you want to
enable Global Voicemail Integration on a 7.1 system, you must
install IP Messaging software on a GVCS, and then set up the
GVCS through the IP Messaging administrator configuration
interface. Next, run
vcx-reconfigure (see Chapter 7) on regional
and branch office IP Messaging servers to enable Global Voicemail
Integration. Refer to the IP Messaging Module Operations and
System Administration Guide for more information and for
configuration options.
■ Call server software
Supported on multi-site systems that include servers at regional offices
with or without branch offices
■ Call Records server software
Supported on multi-site systems installed on a single server for
regional offices with or without branch offices
■ Authentication and Directory server software
Supported on multi-site systems that include servers at regional offices
with or without branch offices
You should upgrade each server from a locally attached console. The
upgrade procedure includes a reboot of each upgraded server. If you
perform an upgrade remotely (using a secure shell client, for example),
you will be logged out when the reboot occurs. When you log back in, it
may not be apparent that the upgrade has completed. If you enter
commands before the upgrade has finished, the upgrade will fail.
Upgrading a
Single-Site System
With Two Servers
Single-site VCX systems can have either two servers or four servers.
■ In a two-server configuration, each server runs IP Telephony server
software and IP Messaging server software.
