(18BW26.x and 20BW25.x) Load From Cold
Prerequisites
Overview
The following procedure describes and illustrates the system software loading process commonly referred to as the Load From Cold (LFC). It is important to follow the steps listed below in order.
1 Software Deliverable for Console
Procedure
- GEHC-CT-OS-DOC1686915R4-2015R3
- CT Applications Software 18BW26.x/20BW25.x
2 Pre-LFC Checks and Information Gathering
Procedure
- Confirm that a current System State Backup Media is on site.
If unsure of the status of the System State, execute System State Save Restore procedure found in
the Software Chapter of this manual. Save a System State Backup to
either DVD-RAM or USB Media.note: Format USB to FAT32 before save a system state, type:
{ctuser@hostname}mkfsUSB
- Remove all media and USB drives from Peripheral Towers before starting the OS Load of the LFC process.
3 Information Capture
3.1 Common Information Capture
Procedure
- Record Autovoice Volume control settings (ALT-F3 by Toolchest, upper right corner).
- Write down all of the system INFO information on the reconfig screens, including the network information.

- notice
- Verify and record specific system hardware configuration.
- Open a shell and type the following:
{ctuser@hostname}cat /usr/g/config/INFO
- Record screen information.
- Open a shell and type the following:
- If the console has Connect Pro installed, write down the information when you run installhisris so it can be entered on the new console when installing the Connect Pro option.
- PPS server information can be confirmed by the following procedure.
- {ctuser@hostname} cd /usr/g/ctuser/nuevo/resources/pps
- {ctuser@hostname}
cat pps_scp.properties
scp.hostname=<Local hostname>
scp.ip=<SCP_IP>
scp.port=<SCP_Port>
scp.calledAeTitle=<SCP_AE_Title>
scu.calledAeTitle=<SCU_AE_Title>
- Close the Service Desktop window in the upper left corner of the screen.
3.2 Information Capture for Option Installation
If your system does NOT have Exam Split option, skip this section. Perform these steps before powering down your current Operator Console:
- Open a Unix Shell and type the following:
- {ctuser@hostname} su -
- Password: #bigguy
- [root@hostname] ls -l ~ctuser/ves/.hesMode
note: There are no spaces in the phrase ~ctuser/ves/.hesMode - Examine the results.
- If the results are similar to:
-rw-r--r-- l ctuser users 0 Apr 3 12:43
/usr/g/ctuser/ves/.hesMode
The HES (Hard Exam Split) mode is configured.
- If the results show 'No such file or directory', then VES (Virtual Exam Split) mode is configured.
- If the results are similar to:
- Record Exam Split Mode (Hard or Virtual). This info will be used during the LFC Options Installation.
- Close the Unix Shell.
4 Operating Software (OS) Load (Approximately 20 minutes)
Procedure
