vCenter / PSC appliance fails to configure NTP

September 7th, 2016 No comments

I have been rebuilding my lab this week and ran into some issues when trying to configure NTP on the PSC and VCSA that were freshly deployed on 6.0U2.

The error I got can be seen below, which was not extremely helpful unfortunately.

Removing stale hosts/cluster compute resource entries from vRA 7

April 1st, 2016 No comments

Update: This did remove all my compute resource configuration within my fabric groups (potentially because I did not create reservations yet which actually utilized these fabric groups and compute resources that I did not want to remove). Please use with caution!

After having finally found the time to set up the latest version of vRealize Automation (7.0.1) and adding my vCenter endpoint everything was looking good, until I got carried away, performed some other tasks, renamed a few clusters in vCenter and then went back to configure my fabric groups.

Too bad that data collection already ran before I renamed the clusters… so as a result I now had stale entries for compute resources when trying to add a new fabric group.


As we can see there is no more cluster called “Lab” in my environment. I tried using a tip from someone else who had seen this in the past and stopped and restarted the agent but that didn’t exactly help.

Doublecloud’s Super vCenter – Part 1 Installation

March 6th, 2016 No comments

Quite a bit of time has passed since new year’s and I am trying to keep up with my reading resolution, having finished the first book Systems Performance: Enterprise and the Cloud at least. I diverged a bit into some more salesy literature for now and studying for the VCAP-CMA design beta has also taken a bit of time (and some new stuff was released on the Wii U that I just can’t stay away from right now, I simply love Zelda games…).

In between the last post and now a couple of new vExpert freebies have also been released and while I ordered a couple of new shiny toys for the homelab today (Intel NUC, have been waiting for 32GB RAM models for years and now they are finally available) I though of actually taking a couple of those vExpert for a testdrive.

The topic of monitoring, Linked Mode etc. came up in the vExpert slack a while ago and one of the products mentioned to cope with those challenges was DoubleCloud’s vSearch aka “Super vCenter”.

VMware Workstation drivers fighting over NICs – Windows is the clear loser

October 19th, 2015 No comments

It has been a while since my last post and I partly blame the job change on it. lots to do, little time.

This weekend my laptop lost power and offered me the possibility to go into full nerd mode for a change of pace again. I basically updated to Windows 10 the day it came out and have been very happy with it since but after the power outage the login mask would suddenly completely freeze.

After lab 1 was done a small coffee break directly leads into lab 2 showing the students on how to check if a specific VMware certificate template was created.

“nasty” SSL/SSO lab exerices – lab 1

January 20th, 2015 No comments

In the last post we finished building the lab, all components are in place to actually follow the lab guide now. So the next couple of posts will consist of shorter lab exercises the students had to do during the actual training to get comfortable with using SSO and replacing/troubleshooting SSL certificates in a vSphere environment.

Planning and building the “nasty” SSL/SSO lab – Part 3

January 18th, 2015 No comments

This time we will be setting up the vCenter Server for one of the lab sessions later. Since we intentionally want to break something we need a very specific procedure though.

Planning and building the “nasty” SSL/SSO lab – Part 2

January 4th, 2015 No comments

As indicated in the last post this one will deal with the actual install and setup of the lab infrastructure. We will need 4 VMs as the basic minimum configuration. So let’s start by building out the Domain Controller machine.

Planning and building the “nasty” SSL/SSO lab – Part 1

January 3rd, 2015 No comments

As promised I wanted to start a small series on the content I developed to internally train TSEs to better handle SSL and SSO cases in vCenter Server 5.5. The whole training went from a mere 1 hour presentation to a full 2 day course and could easily enough be extended by another set of lab exercises and adding different products. As there is no hands on lab for replacing SSL certificates yet

Using hMailServer in the lab

December 27th, 2014 No comments

In a recent training for vCenter Server Orchestrator 5 we had to build a workflow that would leverage an email server to send mails. The lab was more of a theoretical practice as no actual email server was installed and a full blown Exchange is overkill for most homelab scenarios. I also do prefer Windows over any sendmail configuration at any point in time and have discovered hMailServer to be a perfect fit for my lab setups.
