Chapter 15 Upgrading or reinstalling the software 761

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

4At the Software Management# prompt, enter the following command:

>> Software Management# cur		Status
Version	Name
-------	----	------
x.x	NSNAS	unpacked
z.z	NSNAS	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 /boot/ software/activate command.

Note: When you activate a software upgrade on a Nortel SNAS 4050 device, all the Nortel SNAS 4050 devices in the cluster reboot. All active sessions are lost.
