A Journey Through Discovery

  • Reset VxRail Root and Mystic Accounts

    I have been working with clients that are using VxRail for their infrastructure. While administering these VxRail deployments, sometimes the mystic or root accounts get locked, the password’s expire or are just plain lost. Either way, it is a very frustrating situation to find yourself in. Turn to Google and search for reset VxRail Manager…

  • Changing the Primary Network Identifier (PNID) on vCenter

    Preface This has been occurring to me a lot lately. vCenter gets deployed and configured with a hostname. You are likely not giving it much thought until later when a particular situation arises. When it’s time to upload Transport Layer Security (TLS) certificates and you receive the following warning, “Error occurred while fetching tls: Invalid…

  • How to Get Values from a Nested Ansible Dictionary

    The following block of code is used to get a list of files from a directory. It then registers a variable with the contents of any files that were found. This next block is used to display the contents of the registered variable. The result of the debug command is below. Notice that the “files”…

  • Prepare vRealize Operations for Ansible

  • Ansible and VMware

    I recently started experimenting with Ansible. I am still learning the mechanics of how it works and if it can actually be benefiting. The motivation behind this is in learning how to more effectively perform certain tasks using Ansible. In particular, for me, I want to quickly, accurately, and efficiently apply DISA STIG to VMware…

This is how it all started…

I started this site with the intent to aggregate as much information as possible in one place. I use this to record lessons learned or frustrating configurations I have experienced on the job or just tinkering (learning) and just couldn’t find a better resource available. I have tried to be as thorough and accurate as possible, but technology is rapidly evolving and every environment is different. I may miss things along the way and my setup most likely differs compared to yours.

I hope you find this site has some value to you.
