DSI Signaling Server SGW Mode User Manual Issue 5

4.14 Creating a System Archive

A system archive comprising the binary configuration file, installed software licenses and current software

binary distribution file can be created on the Signaling Server portable media (CDROM or USB device) and

later used to restore the system to current working status.

As the Signaling Server starts up a copy is created of the following system files which are stored in the syslog

subdirectory of the siuftp account.

Table 2. System Files Stored in the syslog Subdirectory

The files can be recovered from the syslog directory using FTP as described below:

ftp 192.168.0.1user siuftppassword ********cd syslog

asciiget config.txtget sgw.licbinget sgw.tgzget sgw.licget modcapget config.CF1get SDC.CF3get

SDC.CF4bye

To create the archive all the files can be transferring to an ISO9660 format CD or USB device. To check that

the archive media device has been created without error - return the device to the unit and enter the

following command:

CNUPI:DTYPE=SYSKEY;

If this command returns ‘EXECUTED’, then the media contains a valid software license.

4.15 Restoring System Archive

The Signaling Server is restored to the archived software, configuration and licensing states when the

archive portable media device is placed in the appropriate drive and the system is re-booted.

On re-boot, the system will restore all files from the portable media device to the system. Configuration files

from the portable media will overwrite any in the SIUFTP directory.

Note: Once the system has been restored you must ensure that the portable media device is removed

from the unit, otherwise on subsequent re-boot the system will reinstall the archive files.

If the user changes dynamically configurable data on the system using MMI (i.e., MMI commands are

described in this manual with the attribute ‘CONFIG’), a new configuration backup can be added to the syslog

directory in the siuftp account. To do this without restarting the system, enter the following command:

CNBUI:DTYPE=SYSCFG;CNBUI:DTYPE=CONFIG;

Following this command, a new CD archive should be created following the procedures identified in

Section 4.14, “Creating a System Archive” on page 35.

Note: The user can also re-install any of the previously backed-up system files (identified in

Section 4.14, “Creating a System Archive” on page 35), or install a new text configuration file

using FTP rather than from portable media. In this case, files can transferred to the unit by FTP.

File Description

sgw.tgz A binary file containing the current software distribution on the system.

sgw.lic A text file containing the current software licenses active on the system, if present.

modcap

A binary file containing a software license allowing SS7G2x operating software to function on this particular

system.

config.CF1

A binary configuration file containing dynamically configurable data that is common to all modes of operation. IP

address configuration and parameters set by the CNSYS command would for example be stored in this file.

config.txt The text configuration file for a SIU, if present.
