npu(config)# reboot from shadow [<shadow image name>]
In the above command, you can specify the shadow image name that is to be used
for NPU reboot. If you do not specify a value for the shadow image name
parameter, the shadow image that was last downloaded is used for rebooting the
NPU.
B.2.1.4 Step 4: Making the Shadow Version Operational
After you reset the NPU with the shadow image, and ensure that the NPU is
functioning correctly with the shadow image, you can make the shadow version as
the operational version. The next time you reset the system, the shadow image
that you make operational is used for rebooting the NPU.
To make the shadow version as the operational version, run the following
command.
npu(config)# switchover npu
After you run this command, the operational image is swapped with the shadow
image. The next time you reset the NPU, the system boots up with the swapped
image.
