Summit WM Controller WM20 rescue procedure

The Summit WM20 Controller provides a separate rescue partition on which a minimal copy of the
kernel is installed. The partition is accessed as a special mode of the system's bootloader. Rescue mode
boots into the rescue partition, loads the minimal kernel and corresponding filesystem. It also mounts
the primary system partitions as locally accessed mount-points. The user is then presented with a menu
as to how the system's rescue is to proceed.
CAUTION
If the HDD has failed, use the Rescue procedure to revert to your previous image. You must first replace the
corrupted HDD with a new one that has the factory default image on it. You can then use the Rescue procedure to
revert to your previous image with your old configurations.
The Summit WM Controller WM20 supports the following methods for rescue:
Local – Rescue file is directly present on filesystem
●
Remote – Rescue file is located in a remote FTP server
●
Local rescue
The rescue partition contains a rescue image. The rescue image is typically installed at manufacturing
time, during the image cloning process. The user can select the Local rescue method to utilize the local
stored file as the rescue image.
Remote rescue
The remote method allows the user to directly install the rescue image as part of the download process.
By default the remote image is not stored in the local partition. The user is given the option to save
downloaded rescue image into the partition.
