vSAN Locator LEDs – HPE

vSAN Locator LEDs – HPE Short tidbit of knowledge today. vSAN includes the functionality to turn locator LEDs on vSAN storage devices on or off to help identify the location of a specific storage device, perfect for a visual indication of a failed drive. I wasn’t aware until recently that to get this working with HPE servers there is a prerequisite requirement to install the HP Smart Storage Administrator CLI – good information to know… Read More »vSAN Locator LEDs – HPE

VMware Cloud Foundation – Can’t deploy vRealize as no AVN is available

VMware Cloud Foundation – Can’t deploy vRealize as no AVN is available For reasons entirely of my own making when I deployed my current lab, I did not create the VCF AVN networks during deployment.  This wasn’t a problem at the time as I was focused on vSphere with kubernetes.  However, I did come to regret this just recently as in particular I wanted to deploy vROPs and explore the kubernetes integration that is available… Read More »VMware Cloud Foundation – Can’t deploy vRealize as no AVN is available

Project Octant – Graphical User Interface for Kubernetes

Project Octant – Graphical User Interface for Kubernetes By introducing new layers of abstraction through kubernetes, it is possible that this comes with additional complexity. Project Octant is a useful tool to add to the arsenal when trying to navigate how resources within a kubernetes cluster hang together, to describe kubernetes clusters in a manner that is perhaps more friendly to existing operation teams. Octant is a tool for developers to understand how applications run… Read More »Project Octant – Graphical User Interface for Kubernetes

Tanzu Kubernetes Cluster ‘default’ storage class not persisting

  • simon 

Tanzu Kubernetes Cluster ‘default’ storage class not persisting In my last post, when I was deploying kubernetes resources via kubeapps I came across what seemed to be an issue where the default storage class I was passing to the cluster wasn’t persevering.  To try and resolve the issue I’d been passing the below from within my Tanzu Kubernetes Cluster but it wasn’t remaining in place; “kubectl patch storageclass vi-cluster1-vsan-storage-policy -p ‘{“metadata”: {“annotations”:{“storageclass.kubernetes.io/is-default-class”:”true”}}}’” I flagged it… Read More »Tanzu Kubernetes Cluster ‘default’ storage class not persisting

vSphere Kubernetes – Force deleting stuck ‘terminating’ namespaces and contexts

  • simon 

Like many vSphere administrators and architects following the release of vSphere 7 and VMware Cloud Foundation 4 I’ve been upgrading my lab and starting to play with the VMware Tanzu Portfolio.  I’m not going to detail how to get that working, Cormac Hogan and David Stamen have put together great guides for that.  This post is just posting a fix for a problem that I’ve encountered in the lab Namespaces and Contexts stuck ‘terminating’ Something… Read More »vSphere Kubernetes – Force deleting stuck ‘terminating’ namespaces and contexts

vSAN Orphaned Objects

  • simon 

I recently got asked a question about how to managed orphaned objects in vSAN, previously with VMFS this was being managed with a PowerShell script, but the customer couldn’t get it to work with vSAN.  Which is expected behaviour as managing these vSAN namespace associations/objects is not possible via the GUI or script. Instead these namespaces can be managed using RVC or the Ruby vSphere Console if required. The following blog details the use of… Read More »vSAN Orphaned Objects

Extending Simple Network Mapping – TCP Port Descriptions

  • simon 

Simple Network Mapping In an earlier post I demonstrated how you could use a very simple toolset such as VMware tools and Netstat to create visualisations for what devices are talking to each other on a network.  I had a few thoughts of my own on some additional simple steps that could be taken to improve the data and visualisation still further. A few conversations on Twitter and LinkedIn, convinced me to pull them together… Read More »Extending Simple Network Mapping – TCP Port Descriptions

Simple Network Mapping using VMware tools and Netstat

  • simon 

Network Mapping I had fun working out a simple way to extend application discovery using VMware tools,  following a retweet or two (or 17) it seems like a lot of folks enjoyed reading about it too.  So fresh from putting together a simple method to interrogate application data, helped by some very clever engineering from the VMware tools team and the function from William Lam, I thought I’d write up how we can reuse the… Read More »Simple Network Mapping using VMware tools and Netstat

Extending Application Discovery in vSphere with VMware Tools 11

  • simon 

Application Discovery I read with great interest the recent article from William Lam regarding application discovery being included in VMware Tools version 11.  I’ve worked for many organisations in the past where having access to this information has been crucial for both strategic planning and operational activities.  Previously to get that information to support those activities I’ve used tools such as invoke-script or agents already installed on servers to run scripts that return the required… Read More »Extending Application Discovery in vSphere with VMware Tools 11

UK VMUG UserCon 2019

  • simon 

One of the highlights of last year was the VMUG National user conference held at the space centre in Leicester.  A fantastic venue for not only the conference event but for the pre event vCurry and quiz, so it’s no surprise that it’s being held there again this year.  The vCurry on the 26th and the conference on the 27th. There is a great agenda covering a huge range of topics.  From a technical standpoint… Read More »UK VMUG UserCon 2019
