Using PowerShell to enumerate Log Insight events

When using the VMware NSX Distributed firewall, it’s common to use vRealize Log Insight for firewall rule analyses but there is a little problem with it, which I will try to explain and resolve. The great thing about the VMware NSX Distributed Firewall is that you can assign vSphere objects directly to the firewall rules. VMware NSX takes care of the translation of these objects … Lees verder Using PowerShell to enumerate Log Insight events

LACP and vSphere (ESXi) hosts: not a very good marriage

I receive a lot of questions from customers if they should implement LACP rather or not, so without further ado: In this blog I’m going to talk about if it is a good idea to configure LACP between your ESXi hosts and the physical switched network? The Link Aggregation Control Protocol delivers enhanced features for a Link Aggregation Group (LAG), ensuring a stable connection between … Lees verder LACP and vSphere (ESXi) hosts: not a very good marriage

PowerCLI: Enable VSAN on existing (stretched) vSphere clusters as autonomously as possible

Introduction During my career I’ve done quite some vSphere and VSAN implementations . The hardest part of implementing VSAN on a vSphere cluster is (usually) the network part. Especially in a stretched VSAN cluster configuration, there are some specific network requirements/best practices which should be followed, but because you don’t implement them on a daily basis you forgot some of the settings: you usually keep … Lees verder PowerCLI: Enable VSAN on existing (stretched) vSphere clusters as autonomously as possible

PowerCli: Creating VMK-if on the vmotion netstack on a DVS (with the correct gateway IP configured)

Good scripts are created out of frustration: And here’s a good example of this statement! I wasn’t able to find a script which was able to create a VMK-interface connected to a DVS, being a part of the vmotion netstack AND with a default gateway configured at the netstack-level (and not the VMK-if. The majority of the scripts (which I stole shameless from my collegeau … Lees verder PowerCli: Creating VMK-if on the vmotion netstack on a DVS (with the correct gateway IP configured)

PowerCLI: retrieve VMhost routes used for stretched VSAN clusters.

When configuring a stretched VSAN cluster, the VSAN VMkernel interface is connected to the “default” netstack and manual routes must be added which point to VSAN subnet gateways, which enables VSAN communication in a stretched cluster configuration. Without the additional routes add to the ESXi-hosts, communication to the witness appliance and the remote site is not working. This script below shows the manual added routes … Lees verder PowerCLI: retrieve VMhost routes used for stretched VSAN clusters.

PowerCli: bulk change ESXi root passwords with vCenter

sometimes you have to change the root password for all ESXi hosts.You can use the PowerCLI Set-VMHostAccount cmdlet. But this requires you to connect to each individual ESXi host, it cannot be run when connected to the vCenter server. So, I’ve created a (rather small) script which changes the root passwords for all (or a subset) of the ESXi hosts, which are connected to a … Lees verder PowerCli: bulk change ESXi root passwords with vCenter
