Upgrading the vRouter ISO by using "add system image"

When the ISO of the vRouter VHD is changed, perform an upgrade to the ISO by following the procedure in this section.

add system image uses a vRouter ISO file as the image source. It installs the image with existing images and sets the new image as the default boot image. The new image is run the next time you reboot the system.

To prepare for the upgrade, determine the location of the vRouter ISO file and record the name of the file.

To upgrade the ISO, do as foloows:

  1. Enter add system image. Use the location and name of the vRouter ISO file as arguments in the command, as shown in Sample session: "add system image".
  2. Before you reboot, confirm that the new image is loaded and ready to run the next time the system is rebooted.
    Enter show system image; see the relevant example in Sample session: "add system image".
  3. Reboot the system by entering reboot.
The system restarts with the new system image.
