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”.

New Year’s resolution – Some back to basic reading and getting back into the certification game

December 31st, 2015 No comments

I bought a Safaribooks subscription during the black Friday week in my vacation time (who could resist unlimited access to basically every major tech book publisher for less than 300 bucks for a whole year).

As the new year is coming up it’s time for some resolutions as well, mine will mainly include some reading. 🙂

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.

Yesterday I finished reading one of the Packt books I actually enjoyed (which is only a handful to be honest, usually the standard is not too high).

Real life experience on performing a roll back from vRA 6.1 to 6.0.1

March 10th, 2015 No comments

I had to deal with a deployment issue in vRealize Automation yesterday that also included one issue to be the weirdest corner case I have seen so far.

All deployments for any VMs using no vRealize Orchestrator workflow stubs were successful. But let’s be honest, that is pretty boring and doesn’t cover most customers use cases, which means most customers will be using the provided stubs to actually step into the machine life cycle and modify deployment and destruction of VMs using workflows and scripts.

Help my VM is hung/unresponsive – what to collect for GSS and why we need it.

March 9th, 2015 No comments

This came up on twitter today. While this might result in a fast turnaround time for getting the immediate issue resolved it won’t show you the root cause of the hang/unresponsive VM, and let’s be honest normally that is what we are interested in, right? (There will be exceptions to that, if your mission critical and revenue generating system is in that state you probably want to restart it as fast as possible and then go back to the white board and redesign that single point of failure as soon as possible).
