Note The shell prompt does not appear if you have setup a single user mode password.

Step 5 You can change the root password by entering the passwd command.

Step 6 Enter and confirm the new password.

Step 7 Restart the machine.

Backing Up and Restoring Mobility Services Engine Data

This information describes how to back up and restore mobility services engine data. It also describes how to enable automatic backup.

Backing Up Mobility Services Engine Historical Data

Cisco WCS includes functionality for backing up mobility services engine data.

To back up mobility services engine data, follow these steps:

Step 1 In Cisco WCS, choose Services > Mobility Services.

Step 2 Click the name of the mobility services engine that you want to back up.

Step 3 Choose System > Maintenance.

Step 4 Click Backup.

Step 5 Enter the name of the backup.

Step 6 Enter the time in seconds after which the backup times out.

Step 7 Click Submit to back up the historical data to the hard drive of the server running Cisco WCS.

Status of the backup can be seen on the screen while the backup is in process. Three items will display on the screen during the backup process: (1) Last Status field provides messages noting the status of the backup; (2) Progress field shows what percentage of the backup is complete; and (3) Started at field shows when the backup began noting date and time.

Note You can run the backup process in the background while working on other mobility services engine operations in other Cisco WCS windows.

Note Backups are stored in the FTP directory you specify during the Cisco WCS installation.

Restoring Mobility Services Engine Historical Data

You can use Cisco WCS to restore backed-up historical data.

To restore mobility services engine data, follow these steps:

Step 1 In Cisco WCS, choose Services > Mobility Services.

Step 2 Click the name of the mobility services engine that you want to restore.

Step 3 Choose System > Maintenance.

Step 4 Click Restore.

Step 5 Choose the file to restore from the drop-down menu.

Step 6 Enter the time in seconds after which restoration times out.

Step 7 Click Submit to start the restoration process.

Step 8 Click OK to confirm that you want to restore the data from the Cisco WCS server hard drive.

When restoration is completed, Cisco WCS displays a message to that effect.

Note You should not work on other mobility service engine operations when the restore process is running.

Enabling Automatic Location Data Backup

You can configure Cisco WCS to perform automatic backups of location data on a regular basis.

To enable automatic backup of location data on a mobility services engine, follow these steps:

Step 1 In Cisco WCS, choose Administration > Background Tasks.

Step 2 Check the Mobility Service Backup check box.

Step 3 Select Enable Task from the Select a command drop-down menu. Click Go.

The backups are stored in the FTP directory that you specify during the Cisco WCS installation.

Downloading Software to Mobility Services Engines

To download software to a mobility services engine, follow these steps:

Step 1 Verify that you can ping the mobility services engine from the Cisco WCS server or an external FTP server, whichever you are going to use for the application code download.

Step 2 In Cisco WCS, choose Services > Mobility Services.

Step 3 Click the name of the mobility services engine to which you want to download software.

Step 4 Choose System > Maintenance.

Step 5 Click Download Software.

Step 6 To download software, do one of the following:

•To download software listed in the Cisco WCS directory, select Select from uploaded images to transfer into the Server. Then, choose a binary image from the drop-down menu.

Cisco WCS downloads the binary images listed in the drop-down menu into the FTP server directory you have specified during the Cisco WCS installation.

•To use downloaded software available locally or over the network, select the Browse a new software image to transfer into the Server and click Browse. Locate the file and click Open.

Step 7 Enter the time in seconds (between 1 and1800) after which software download times out.

Step 8 Click Download to send the software to the /opt/installers directory on the mobility services engine.

Step 9 After the image is transferred to the mobility services engine, log in to the mobility services engine CLI.

Step 10 Run the installer image from the /opt/installers directory by entering the following command ./.bin mse image. This installs the software.

Step 11 To run the software enter /etc/init.d/msed start.

Note To stop the software, enter /etc/init.d/msed stop, and to check status enter /etc/init.d/msed status.

Manually Downloading Software

If you do not want to automatically update the mobility services engine software using Cisco WCS, follow these steps to upgrade the software manually using a local (console) or remote (SSH) connection.

Step 1 Transfer the new mobility services engine image onto the hard drive.

a. Log in as root, and use the binary setting to send the image from an external FTP server root directory. The release note format is similar to the following and changes with each release: CISCO-MSE-L-K9-x-x-x-x-64bit.bin.gz.

Note The mobility services engine image is compressed at this point.

Note The default login name for the FTP server is ftp-user.
Your entries should look like this example:
# cd /opt/installers  
# ftp <FTP Server IP address>  
Name: <login>  
Password: <password>  
binary  
get CISCO-MSE-L-K9-x-x-x-x-64bit.bin.gz  
<CTRL-Z> 
# 
b. Verify that the image (CISCO-MSE-L-K9-x-x-x-x-64bit.bin.gz) is in the mobility services engine /opt/installers directory.

c. To decompress (unzip) the image file enter the following command:

gunzip CISCO-MSE-L-K9-x-x-x-x-64bit.bin.gz

The decompression yields a bin file.
d. Make sure that the CISCO-MSE-L-K9-x-x-x-x.bin file has execute permissions for the root user. If not, enter chmod 755 CISCO-MSE-L-K9-x-x-x-x.bin.

Step 2 Manually stop the mobility services engine.

a. Log in as root and enter /etc/init.d/msed stop.

Step 3 Enter /opt/installers/CISCO-MSE-L-K9-x-x-x-x.bin to install the new mobility services engine image.

Step 4 Start the new mobility services engine software by entering the following command:

/etc/init.d/msed start

Caution Only complete the next step that uninstalls the script files, if the system instructs you to do so. Removing the files unnecessarily erases your historical data.

Step 5 Enter /opt/mse/uninstall to uninstall the mobility services engine's script files.

Configuring NTP Server

You can configure NTP servers to set up the time and date of the mobility services engine.

Note•You are automatically prompted to enable NTP and enter NTP server IP addresses as part of the automatic installation script for the mobility services engine. For more details on the automatic installation script, refer to the Cisco 3350 Mobility Services Engine Getting Started Guide or Cisco 3310 Mobility Services Engine Getting Started Guide at the following link:

http://www.cisco.com/en/US/products/ps9742/prod_installation_guides_list.html

•If you need to add or change an NTP server installation after a mobility services engine install, rerun the automatic installation script. You can configure the NTP server without adjusting the other values by just tabbing through the script.

Note For more information on NTP server configuration, consult the Linux configuration guides.

System Reset, Defragmenting Database and Clearing Configuration

For information on:

•Defragmenting the mobility services engine database

•Rebooting or shutting down the mobility services engine hardware

•Clearing the configuration file

Refer to the "Initiating Advanced Commands" section on page 4-11 of this configuration manual.
