4.4 Log Files

All commands run during a DIU upgrade are logged in /var/TKLC/log/upgrade/upgrade.log. The log starts automatically when the DIU upgrade software is invoked and rolled each time an upgrade begins.

The diuPreUpgrade_elap.sh script logs its actions to /var/TKLC/log/upgrade/Pre_upgrade_DIU.log. The PostDIUValidation.sh script logs its actions to /var/TKLC/log/upgrade/PostDIUValidation.log.

The technician following these procedures is responsible for enabling screen logging in the selected connectivity application.
