It’s been a while… been a while since I blogged and I’m ashamed to say been a while since I scripted! But there is nothing like a crisis to bring out the scripting guns when we had to restart a 100 odd virtual machines which were hung. Which made me realize that while I had […]
There have been numerous occasions where we were required to gather the list of VMs in the vCenter along with their OS, for audits, for support, to plan patching, etc… But its not always that easy. The vCenter gets the OS details of the VM with the aid of VM Tools in the virtual machine. […]
Consider this part 2 of my vSphere Health Check with PowerCLI series. It’s taken its sweet time, I know, but hey – better late than never eh? 😉 Part 1 is found here (Checking for hosts with alarms disabled) . In this post we’ll discuss how to check the EVC mode of each host cluster […]
In a previous write-up I discussed how to check the Alarm status of ESX hosts in a cluster. Let’s take it a step further and check how we can enable the alarms on an ESX host in order to automate it – so that alarms will be enabled on ESX hosts for eternity, as a […]
Are you planning an ESXi upgrade? or in the middle of a cluster ESXi upgrade and couldn’t track which ones you upgraded and which ones you didn’t? (which is what happened to me 😉 ) So I made a script that would output the build number and version number of ESXi hosts in a cluster […]
In a time of increased demand in web services, its our duty as Sys Admins to ensure that everything is running smoothly. Before doing any advanced optimization, the first step is ensuring that the environment is running with the correct configurations in place. To this end I dug through to the deepest bits of PowerCLI […]
The world is in crisis. A third of the world is in lockdown. The very fabrics of life has been shaken to its very core. An invisible enemy is on the prowl in the streets, bubbles of safety shattered down. An unfamiliar feeling for most generations who have lived in “relative” peace. But while the […]
Maybe you’re upgrading your hosts, maybe you’re trying to run a command on multiple ESXi Hosts, any which way one thing which you will have to do is enable SSH from the vCenter, and disable when you’re done – because annoying as it is, security is important! 😉 It would be especially annoying if you […]
Are you a vSphere Admin facing complaints of Virtual Machine slowness? Are rogue, stale and abandoned Snapshots infesting your infrastructure? Boy have I got the script for you! Sorry about the “as seen on TV” intro, but as a vSphere admin sometimes snapshots do get out of hand. Below is a simple little one-liner using […]
We recently had to check for discrepancies in configurations of ESXi hosts in a datacenter. While they should be identical, we have had issues with DNS working on some hosts while some don’t. So I developed a script that outputs the DNS servers configured on every host of the entire vCenter to a CSV file. […]
