New VOBs for creating vCenter Server alarms in vSphere 6.0

by // Leave a Comment

Here are some new VOBs in vSphere 6.0 that I recently came across which can be useful on getting notified on specific events such failed login attempts in ESXi or detecting a device has gone offline in VSAN as some examples. These VOBs can be used to create vCenter Server alarms to take various actions such as a simple UI notification in the vSphere Web/C# Client to sending an email or SNMP trap regarding the event. For more information on how create vCenter Server alarms using VOBs, please take a look at these two articles here and here which also includes a comprehensive list of past vSphere VOBs in vSphere 5.5 which are still applicable in vSphere 6.0.

VMworld Barcelona #NotSupported Tips/Tricks for vSphere 5.5 Slides Posted

by // 3 Comments

I hope everyone got back home quickly and safely from VMworld Barcelona (unlike myself for those of you who follow me on Twitter, took a bit longer than I had hoped). For those of you who attended my #NotSupported Tips/Tricks for vSphere 5.5 at VMworld Barcelona earlier in the week, I have posted my Sliderocket presentation below as well as the recording thanks to the vBrown Bag team. If you could not attend the session or did not go to VMworld you can view all vBrown Bag Tech Talk recordings by checking out this link here. I highly recommend you check out the ENTIRE presentation as there was an exciting announcement that I made at the VERY END of the presentation.

Disclaimer: I think it should be pretty obvious, but things discussed in the presentation is not officially supported by VMware. Use at your own risk.

I would like to thank everyone that attended my session, really enjoyed the crowd and the questions/discussions afterwards. I know you could have been else where such as the Solution Exchange with a nice beverage, so thank you all for attending and hopefully everyone enjoyed it. I would also like to give a big shout out to vBrown Bag team Jon Harris, Kyle Murray, Damian Karlson and Gregg Robertson for putting together such an awesome event up for the VMware community and for their assistance on quickly getting the AV all setup for my presentation.

Here is the presentation:

Here is the video recording:

Here is a couple of pictures from the audience:

You no longer can install vSphere C# Client on Windows Domain Controller in vSphere 5.5

by // 2 Comments

In the last couple of days I have noticed several folks comment on a new check that has been put in place in vSphere 5.5 which prevents a user from installing the vSphere C# Client onto a Windows Domain Controller system. If you try to install the vSphere C# Client on a Domain Controller system, you will get the following error message:

It is generally not recommended to install additional software on a Windows Domain Controller and I suspect this check was put in place to deter users from installing additional software, including VMware software onto a Domain Controller system. However, for a development environment or home lab, you may want to consolidate multiple applications onto a single system and help reduce the number of Windows systems that you may need to deploy. Luckily there is a way to by-pass this check and I am actually glad one exists as this is something I will need while building out some of internal labs.

Disclaimer: This is not officially supported by VMware, please use at your own risk.

To by-pass the check, you will need to launch the vSphere C# Client install from the command-line and pass in the following arguments:

VMware-viclient.exe /v "SKIP_OS_CHECKS=1"

Now the installer should allow you to proceed with the vSphere C# Client installation.
