76Upgrading the NVG Software

For minor and major releases, the software upgrade will take part synchronously among the set of VPN Gateways in a cluster. If one or more VPN Gateways are not operational when the software is upgraded, they will automatically pick up the new version when they are started.

Note: If more than one software upgrade has been performed to a cluster while a VPN Gateway has been out of operation, the VPN Gateway must be reinstalled with the software version currently in use in that cluster. For more information about how to perform a reinstall, see “Reinstalling the Software” (page 70).

When you have downloaded the software upgrade package, you can inspect its status with the /boot/software/cur command.

Step Action

1At the Software Management# prompt, enter the following command:

>> Software Management# cur

Version Name Status

------- ---- ------

7.0.1SSL unpacked

5.1.5SSL permanent

The downloaded software upgrade package is indicated with the status unpacked. The software versions can be marked with one out of four possible status values. The meaning of these status values are:

•unpacked means that the software upgrade package has been downloaded and automatically decompressed.

•permanent means that the software is operational and will survive a reboot of the system.

•old means the software version has been permanent but is not currently operational. If a software version marked old is available, it is possible to switch back to this version by activating it again.

•current means that a software version marked as old or unpacked has been activated. As soon as the system has performed the necessary health checks, the current status changes to permanent.

To activate the unpacked software upgrade package, use the activate command.
