KVM Upgrade Saga: Open vSwitch Woes

I recently rebooted my KVM server. When I do this, I often have to run a script to update Open vSwitch by removing unused ports, but this reboot messed up my entire iSCSI bond and vSwitch configuration. It looks like some of the control files for when you reboot the node were broken and needed to be repaired. Now, I am still not sure why these steps are required, but they do fix the problem for me.

vSphere Upgrade Saga: Upgrading to vSphere 6.0 U1

To keep vSphere installs secure, it is often necessary to patch or upgrade them in a specific order, as outlined in KB 2109760, which has been our guide for the last few parts of our upgrade saga. However, patching vCenter 6.0 vCSA is not as easy as it looks. The instructions in the online manuals are only apropos for upgrading from vCenter 5.1 or 5.5. For vCenter 6.0, they contain information only valid once you have Update 1 involved. So, how do we proceed? Continue reading vSphere Upgrade Saga: Upgrading to vSphere 6.0 U1

Foray into Jenkins, Puppet, Docker, and Photon: Part 2

In my Foray into Jenkins, Puppet, Docker, and Photon article, I discussed how to set up Photon, Jenkins, and Docker and how I was able to use Jenkins to deploy a Photon template. However, this template was a simple template with just Docker set up within it: a template that could become anything required, run any Docker container. The next step was to deploy a container within Photon. For this, I chose NGINX. Continue reading Foray into Jenkins, Puppet, Docker, and Photon: Part 2

Foray into Jenkins, Puppet, Docker, and Photon

I have made a foray into Jenkins to deploy VMware Photon within my vSphere environment. This foray has the end goal of using Jenkins, VMware Photon, and Docker to deploy applications within my hybrid cloud. I have an increased need to deploy web properties as well as to automatically apply in-depth testing to those properties. Quite frankly, the amount of time it takes me to do these things by hand is just getting to be too much of a time sink, so now it is time to use modern tools to augment my existing scripts. Here is my journey into the new world. Continue reading Foray into Jenkins, Puppet, Docker, and Photon

vSphere Upgrade Saga: 6.0 Upgrade through SRM

There are many steps to the upgrade of vSphere, as outlined by KB Article 2109760, with the steps for my environment starting at step 4 (vCNS). However, before I could start my upgrade, I had to upgrade any third-party systems first, as well as to upgrade any Microsoft Windows Servers. Everything went fine for vCNS, View Composer, and View Connection Server. However, problem creep started with the View security server (not really on the list, but if you update the Connection Server, you have to upgrade any security servers at the same time).
