Recently I upgraded my home test lab with a new ESXi white box host. This host is a custom built PC that runs an Asus Gryphon Z97 micro-ATX motherboard. A few people have asked me how I got ESXi 5.5 running on the Asus Gryphon Z97, so I thought I would post up how I did it here….
By default, all domain-joined servers and workstations synchronise their time with the PDC Emulator Domain Controller. However how do you configure Windows Time synchronisation for the PDC Emulator and for non-domain joined machines?
This article explains how to configure Windows Time to synchronise an external time source (NTP server), whether that be internal to your network or an internet NTP server.
Once I built my ESXi 5.5 hosts in my test lab and added them to my vCenter environment, they both had a yellow warning prompt stating: “No coredump target has been configured. Host core dumps cannot be saved”
The good news is I was able to fix this, so I thought to document the solution in case anyone else has the same issue. All the details are below…
I wanted to upgrade the memory on my vSphere 5.1 vCenter server to 16GB and I didn’t have hot-add enabled. I powered off the VM, connected directly to the host and re-configured the VM as required and then clicked OK.
At this point, I got an error saying “Access to resource settings on the host is restricted to the server that is managing it: X.X.X.X”.
The host things it is still being managed by vCenter so it won’t let me edit the VM. vCenter server is powered off so that I can edit the VM (as hot-add is not enabled the VM has to be powered off to change the memory amount).
This is how to fix this issue…..

As of September 2015, I have released version 2 of my PowerCLI Script Template, which includes a number of improvements over this version, in particular the use of the new PSLogging PowerShell module that significantly improves the creation and management of log files.

Version 2 of the template is available here – PowerCLI Script Template v2.
A while a go I posted up my PowerShell Script Template which turned out to be pretty popular with fellow PowerShellers.
I recently create another slightly modified template when working with PowerCLI, so I thought I would share it here. Here is my PowerCLI Script Template to be used for all your VMware scripts…
Have your tried to ping your computer or server and it fails even though you know that it is online and connected to the network? One of the reasons why this fails could be because ping is disabled in the Windows Firewall. This article discusses how to resolve this and allow ping through the Windows Firewall.
