Aegis Micro NRC 2.0.1 manual Clean Command, Upgrade Procedure

Page 40

CLEAN Command

The CLEAN command removes all command, command acknowledgement files and system files from code_changes directory tree.

If the CLEAN command file is present in code_changes directory during an NRC system bootup, all the files in the code_changes directory tree will be deleted and hence cleaned.

Once this process is completed the CLEAN command file in code_changes is simply deleted – there is no acknowledgement file generated for this activity.

Upgrade Procedure

To perform a software upgrade, the necessary files need to be downloaded into the NRC system itself. The following describes how to transfer update files and command files to the NRC.

Part 1 – Set up the NRC system to accept incoming files

The NRC file system is set as “ read-only” , which doesn’t allow files to be written to the file system. In order to change this, an ssh shell session needs to be established with the NRC, through which the NRC configuration utility can be run.

Step 1: Open up a new console session on the unix workstation.

Step 2: From this console session open up an ssh terminal session into the NRC system

#.ssh root@<NRC ip address>

#.password <enter NRC root password>

Step 3: Once the NRC Configuration Utility appears, "ctrl-c" out of this application and leave this session open.

Part 2 - Download the new NRC system files

Step 1: Open up a new console session on the unix workstation

Step 2: From this console session use scp to download the necessary NRC system files into code_changes/updates and new display files into code_changes/updates/lcd

eg. to download a new CCPServer

#scp CCPServer root@<NRC ip address>:/root/code_changes/updates

#password <enter NRC root password>

-an acknowledgement of 100% complete will be echoed back to the terminal window for each file transferred.

Step 3: Repeat Step 2 as many time as is needed to download all necessary files. Note that scp supports wildcarding, so multiple files can be downloaded in one command.
