Recently I added some hardware, and once I did, my vSphere hosts were no longer within the profile; neither were they at the latest patch level. I would have expected little to change within the host profile, but once you add hardware, things change in the host. The same thing happens during every update in which either new features are added or bug fixes are made to the subsystems a host profile cares about.

Before upgrading to vSphere 5.5, I ensured that my host profile was up-to-date and on all nodes. After upgrading, it is important to continue update the host profiles immediately after upgrading. However, the normal way to update profiles, using the vSphere .NET Client, may not work. When I tried it, no matter which host or profile, and whether new or old, the profile would not update. I received a range error. A quick search found nothing but did hint at a few things. Many days later, I restarted the .NET client and noticed once more the message at the top that says:
“The traditional vSphere Client will continue to operate, supporting the same feature set as vSphere 5.0, but not exposing any of the new features in vSphere 5.5.”
After my upgrade to vCenter 5.5, there were still a few things that needed to be tweaked to fully upgrade my environment. I was in a working state, but now I needed to plug in all the bells and whistles I normally use, such as Host Profiles, VIN, and HP Insight Control, as well as vCenter Log Insight (which is a fairly handy troubleshooting tool). All of these are relatively little things, but they take a fair amount of effort to get right. So, where to begin? By ensuring that I can manipulate the vSphere consoles without actually logging in to each of the consoles. I did not need this for some of the bells and whistles, but I do need it for other things.

This is the week end I move all my existing hosts to vSphere 5, to make way for some other work. Actually, I will migrate 2 of 3 hosts, while leaving one host at vSphere 4, more later on why. While Host Profiles has greatly improved, it is still not sufficient when updating and migrating nodes that use physical virtual NIC devices such as HP Flex-10. Why? Because they want to know the MAC Address when you apply the profile. This is a chicken and the egg sort of approach to Host Profiles.

In my continuing story on upgrading to VMware vSphere it is possible to use Host Profiles even without an Enterprise Plus license, at least for a short period of time. Check out my Blue Gears blog on Network World for the complete story.
