At work we recently had a health check performed on our virtual environment. When the results came back, and I noticed a trend with our legacy VM hosts. Particularly where we didn’t follow the same standards as we did on the newer hosts. The issue I’ll be talking about, is renaming the local datastores. So now is the time to apply the same standards across the entire environment.… Continue reading
We are starting to decommission the legacy VMware hosts in my work environment. Normally not a big deal or script for a task like this, but give me enough time I found a need. Templates. So you can easily find templates either using the H5 client or PowerCLI.
This cmdlet displays a list of the template VMs that are in the environment, but it doesn’t say where they are located.… Continue reading
PowerCLI to Find Datastore with missing VM
During the last maintenance window at work, we starting having issues with vCenter, so to resolve the issues vCenter services were restarted. After the vCenter services came back up, I noticed one of the servers on a host had lost it connection. To make things worse, the datastore for the VM changed from the human readable format to location name.… Continue reading
With the changes to how VMware Tools will be released, we finally decided to setup Product Locker. These changes were released in September 2015 VMware decided that the tools would be no longer depended on vSphere releases or ESXi builds.
My first script that I ever wrote was a script to build VMs. I was the newest member on the team, and i was giving the task of building 50 VMs for a new project that was getting started. It was a very daunting task, due to the completion date to have these 50 VMs to be completed.… Continue reading
In my environment at work we have a policy that we thin provision all new VMs. We had an issue with a datastore that was running out of space, so I starting looking into it and found that several of the VMs on this datastore were set with thick provisioning on the hard drives.
This outputs a list of VMs with the storageformat that is set to thick. … Continue reading
From time to time, I get tasked with generating a report of production VMs with specs. This normally wouldn’t be an issue, but we have changed our server naming standard a few times, so we have machines with all sorts of names. The one thing in out environment that hasn’t changed is the datastore naming. We have our datastores split up between non-production and production, and each department has their own.… Continue reading
Before I spin up a new VM, I like to check which datastore has the most free space. This can be completed with a PowerCLI command.
The problem with this, it it is too broad. This gets all of the datastores in vSphere, they are not in any sort of order, and it is also getting datastores that i wouldn’t normal use to put a VM on. … Continue reading
