3 Upgrading the controller from version 2.3 to version 2.4
This chapter upgrades the controller from an existing version 2.3 installation to version 2.4.
NOTE: This procedure assumes:
• You have already downloaded the controller software package as described under
“Downloading the controller software” (page 7).
• The provider type was set to UUID when controller version 2.3 was installed on your machine.
• Network Time Protocol (NTP) is already installed and configured on your system.
Where a command in this procedure is shown with multiple lines, the line breaks are inserted at
the points where a space occurs in the actual command.
To install the downloaded HP VAN SDN Controller software:
1. Ensure that you have root access on the Ubuntu system (sudo).
2. Unpack the HP VAN SDN Controller from the directory in which the package is stored:
NOTE: In the following command, two hyphens precede the unpack keyword; that is,
--unpack.
~$ sudo dpkg -–unpack hp-sdn-ctl_2.4.x.yyyy_amd64.deb
(Where x.yyyy completes the actual release version number of the controller. For
example, 2.4.3.0595.)
3. Execute the following command to install software dependencies.
~$ sudo apt-get install -f
If you are prompted with Do you want to continue [Y/n]?, type Y and
press Enter.
4. In the command line window, verify that the sdnc service is started:
~$ sudo service sdnc status
Wait 60 seconds for the sdnc service process to complete. If the service fails to
start, see “Troubleshooting” (page 21).
You should see the following output, which indicates that the sdnc service is started:
~$ sdnc start/running, process nnnn
Where: nnnn is the process ID assigned to the main HP VAN SDN Controller
process (sdnc).
5. Go to “Operating the HP VAN SDN Controller” (page 17).
