vCenter Virtual Appliance Network Settings Reverting

In one of my lab environments my vCenter Server Appliance (VCVA VCSA*) kept reverting its DNS server settings after I changed them in the VCSA web interface (https://:5480).  After changing the Preferred DNS Server and Alternate DNS Server settings to use my Active Directory Domain Controller IPs and then rebooting the appliance, the DNS settings were removed and the Preferred DNS Server setting was reverted to the setting present before I updated it. Losing my DNS Server settings caused me all sorts of issues - my vCenter Server couldn't find ESXi hosts by name, AD authentication failed, … [Read more...]

vCenter Orchestrator Visio Stencil

Here is a Visio stencil containing 118 shapes for vCenter Orchestrator (vCO) that I put together.  It contains basic workflow shapes (start, decision, etc.) as well as other shapes such as directory services, credentials, nested workflows, policies, custom actions and other product specific icons.  If you are mocking up some Orchestrator workflows to automate processes in your virtual data center, these shapes should give you the ability to provide a graphical representation of your ideas to share with your team.

PowerCLI Script to Set DNS and NTP on ESXi Hosts

Since joining VMware, I've built, rebuilt and updated several lab environments (home lab and work labs).  One of the problems I keep running into is incorrect/missing/disabled NTP on my ESXi hosts.  Because lab gear is often abused well-loved, BIOS time is not always correct (long periods of being powered off), settings are all sorts of jacked up (it's a lab, we're engineers, let's break stuff!!!), and documentation is non-existent.  The problem is not just in a lab environment - the number of customer environments I've seen that aren't set to use NTP is much higher than I would have thought … [Read more...]

A Stage Hand in Act Two – Thoughts on Joining VMware

I've been incredibly fortunate over the past several years to have worked with many VMware customers as the Virtualization Practice Manager at Clearpath Solutions Group, as a leader in the Washington DC VMware User Group, and at industry events like VMworld, EMC World, VMUGs, VTUGs and VMware Knowledge Series. As I have engaged with customers large and small, I've seen the realization of the real, tangible benefits of VMware's virtualization solutions to IT organizations and the businesses they serve. I also began to see customers become increasingly interested in solutions beyond vSphere - … [Read more...]
