How to remove the existing VAN SDN Controller, purge data, and the install the HP VAN SDN Controller to the latest version.... 2.4.6
I completely remove the SDN v2.0 controller, and any apps first as I wanted to start from a clean slate - but there are upgrade procedures in the install guide if you need to just do an upgrade
Download the HP SDN Controller from:
https://h10145.www1.hp.com/downloads/SoftwareReleases.aspx?ProductNumber=J9863AAE
SSH into the SDN Controller
Purge the SDN controller, keystone, and any apps, such as protector (shown below)
sudo dpkg --purge hp-sdn-ctl hp-network-protector
sudo apt-get purge keystone
sudo rm -Rf /var/lib/keystone/
Follow my install guide for 2.4 - here
BUT
Before you start the controller, there is a current issue with accessing the HP SDN controller with Chrome / Firefox due to a recent browser patch which prevents you logging onto websites which use SSL v3.0 because of all the recent MitM vulnerabilities.
to fix it, I followed this:
Then start your controller :)
