25.6Update Mode

To perform the update, the CMM will enter an update mode to prevent interference from other processes that may write to the flash and to unmount the JFFS2 drives that may need to be repartitioned.

In the update mode, all CMM applications will be stopped. Any user defined processes that are running must also be stopped. Hooks in the update process will be provided to allow these processes to be stopped by calling user scripts located in /home/update/scripts/ if they exist. The update process will execute any scripts that match the following pattern: /home/update/scripts/K*. Scripts will be execute in alpha-numeric sort order. Getting a directory listing using the “ls” command will display the order the scripts will run. User scripts should follow the convention of returning a “0” if successful and a non-zero for failure. The update process will not fail if a script returns a failure, however, the update process will fail if the flash drives cannot be unmounted when necessary.

Before unmounting the JFFS2 drives (/etc and /home), /etc will be copied to ram disk /usr/local/cmm/temp/update/etc to retain user and system configuration information.

Because all CMM applications are stopped, systems running with redundant CMMs will lose redundancy during the firmware update process.

25.7Update_Metadata File

The Update_Metadata file included in the update package is used by the update process to determine the platform, firmware package version, files, sequence, update method, location, and any other data required to update the individual components in the update package.
