vSphere 7 – ESXi upgrade

So having upgraded vCenter it’s time to do the hosts.  I’d normally use Update Manager for this – which has had an overhaul and is now Lifecycle Manager. One thing to call out here is that I ran a test prior to upgrading my hosts by installing the hypervisor onto a USB stick and booting from that to make sure there were no hardware issues.  I used remote management to attach the iso to the host and plugged in a USB key to install vSphere 7 onto.  If you don’t have remote management the same can be achieved by creating...

Windows 2008 End of Support – VM report

So hopefully everyone has already long dealt with the upcoming end of support date for Windows 2008 as detailed by MS here right? Paying for extended support might be an option at this late stage but good to know exactly what you are dealing with. I have used the following powercli code to query all vCenters for a report on 2008/2008r2 VMs to identify any stragglers or virtual servers that app owners have been too busy to update or mitigate. Change the variables to suit your environment and comment out the filter (highlighted lines below) if you want to use...

Documentation – vSphere Clusters

I have put this function together for the purpose of documenting cluster settings.  Used it a fair bit to gather information on environments that I have come accross that have not been well documented.  In can be used as is but I’m fiddling around with it to produce some further information so likely to be updated in the near future. Hopefully of some use – connect to vCenter from POWERCLI and run the function. get-clusterdetails

Documentation – ESXi Host vMotion IPs

I’ve recently had to audit and document several vSphere environments.  Multiple hosts had been configured manually and there were some mistakes in the IP settings.  I put together this POWERCLI function to report back on these settings and will now use it for documentation moving forward.  Hopefully of some use to others too. Connect to a host or vCenter and give it a go.

Managing ESXi Hosts with AD Credentials

As part of a security hardening exercise or indeed just because, it may be desirable to change the root account of your ESXi hosts to a complex password, bung it in a safe and let you admins connect via their AD credentials. To start with, join your ESXi hosts to your AD domain.  I have pre-created computer objects in my test environment. I have also created an ESX Admins AD security group which by default allows its members admin access to an ESXi host once it has been joined to the domain. To join the domain run the following powercli...

Documentation – ESXi Host Hardware and Build Details

I don’t know many people that enjoy writing documentation but it is a nessesary evil and can give you the opportunity to be creative with how you produce it. Often I will need to document a point in time install for ESXi hosts so have put together the below PowerCLI function to obtain some hardware and build information back.  Running Get-HostDetails after connecting to a host or vCenter There are loads of good examples available but this works well for me. Output as below

Deploy VMs using Templates, customisation specs and POWERCLI

Who doesn’t love a bit of automation these days, I certainly like to use code snippets and shortcuts whenever I can.  Recently I’ve been deploying some VMs in my homelab and thought I would share some of the POWERCLI I use. I have a Windows 2016 template stored in vCenter that I have recently patched and tweaked to my satisfaction and deploy that with a temporary customization spec to deploy and do the initial config (IP settings and domain join). The key commands to use here to get the IP settings are Get-OScustomizationNicMapping Set-OSCustomizationNicMapping Only started playing with these recently...
