Restoring the Rescue Image

The rescue image resides on the wireless controller's hard disk in a separate partition called the rescue
partition; the running software image is stored in the normal mode partition.
You can restore the rescue partition in the rare event that it becomes unavailable or corrupted (for
example, because of a hardware disk hardware error or a power failure during upgrade). To restore the
rescue partition, you must obtain a healthy rescue image and install it on the wireless controller.
A healthy rescue image is available from the following location:
•
The normal mode partition. A locally saved rescue image is delivered as part of the upgrade image
and saved on the normal mode partition during the upgrade process.
