Today I needed to assign some vCenter tags to some VMs I was deploying using vRealize Automation.
The scenario was that the customer did not want backup of VMs deployed by the vRA test environment, and in production they wanted a specific backup tier.
They are using Veeam backup, so the vRA test environment needed to have a NoBackup Tag, and production needed some other tag, depending on the type of server being deployed.
vRO does not provide very extensive support for these operations out of the box, but vRO 7.2 does come with some sample workflows.
To get started with vCenter tagging you need to configure a vAPI endpoint and a vAPI metamodel.

Roman Decker wrote an article about how to move virtual machine between vCenters that are not part of the same SSO domain, using PowerCLI.
I felt like it needed some adjustments to be more dynamic and interactive, so many of the hard coded bits I decided to make the script ask for at runtime.

Network health check is a very useful feature that was introduced with vSphere 5.1 vDS.
What does it do?
The purpose is to test if the VLANs, MTU and Load Balancing settings you defined are actually working. The old way of doing this would be to disconnect all port except one, by either doing a shutdown on the switch port, or pulling out the cable, and then testing, with a VM, if every VLAN still works. This can be a very lengthy process if you have many adapters, but also a necessary step if you want a stable environment.
If you want to know more about how it check the different settings, Joseph Griffiths did a good article on this you can read here: http://blog.jgriffiths.org/?p=877
So why would you ever disable this feature?
Well the health check feature generates a lot of mac table entries as explained in VMware KB 2034795.
An example given is that you have 35 Hosts with 2 Network Adapters each, and 60 VLANs. This will generate (35 * 2 * 60) 4200 mac table entries in your physical switches. And as you can see, this quickly increases. Some switches only has room for 32.000 records or less. Continue reading Should you enable Network health check for your Distributed Virtual Switches
If you need to search your vSphere Datastores for orphaned VMDK files, Luc Dekens made a script that can help you.
Another possibility is to use rvTools.
Tired of having to update all your servers manually, or with Microsoft WSUS, but without control?
Are you tired of wasting 1-2 hours, every time you deploy a template, for it to install all the latest patches?
Why not automate it the easy way?

I just upgraded the vCenter in my test lab, and I got an error after the first part of the process. When it was about to migrate data from the old VCSA 6.0 Server.
I restarted to process but this time is was unable to get information from my source VCSA server. In the log I had the following errors:

I quickly discovered the reason. My root password was expired and it wanted me to create a new password for root.
