74 Upgrading the NVG Software
Performing Minor/Major Release Upgrades
The following description applies to a minor or a major release upgrade.
To upgrade the VPN Gateway you will need the following:
•
Access to one of your VPN Gateways through a remote connection
(Telnet or SSH), or a console connection.
•
The software upgrade package, loaded on a FTP/SCP/SFTP server
on your network.
•
The host name or IP address of the FTP/SCP/SFTP server. If you
choose to specify the host name, note that the DNS parameters
must have been configured. For more information, see the "DNS
Servers Configuration " section under Configuration Menu>System
Configuration in the Command Reference.
•
The name of the software upgrade package (upgrade packages are
identified by the
.pkg
file name extension).
It is important to realize that the set of installed VPN Gateways you are
running in a cluster are cooperating to give you a single system view.
Thus, when performing a minor or a major release upgrade, you only
need to be connected to the Management IP address of the cluster.
The upgrade will automatically be executed on all the VPN Gateways in
operation at the time of the upgrade. All configuration data is retained. For
a minor upgrade, normal operations are usually unaffected, whereas a
major upgrade may cause the VPN Gateway to reboot.
Access to the Management IP address can be accomplished through
a Telnet connection or SSH (Secure Shell) connection. Note however
that Telnet and SSH connections to the VPN Gateway are disabled by
default, after the initial setup has been performed. For more information
about enabling Telnet and SSH connections, see
“Connecting to the
VPN Gateway” (page 136) . When you have gained access to the VPN
Gateway, use the following procedure.
