In my work environment we have made strives to simply our VMware environment. One of them is using the content library for templates and ISO files. We do this so we make sure the everyone is using the most current golden image. Also with the content library you can sync them from primary site to secondary site without issues.… Continue reading
Automate Removal of VM Snapshots
When I come up with an idea for a blog post, normally I don’t review what ideas I have already wrote about. I should because I would have noticed another post about snapshots I wrote earlier this year. This post is different as it has more cowbell, err automation. Everybody loves automation right? … 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
This task sounds very simple. Target the VM, then import to the primary content library for replication to the subordinate libraries. This task can be accomplished right now with a few clicks in the GUI. I’m not a GUI kind of person, I like the mash the keys to get stuff done. So after a lot of research, I found that the PowerCLI commands to perform this function just don’t exist at this point.… Continue reading
Generating VM Tags with PowerCLI
With the our new infrastructure upgrade it also included an upgrade to our backup solution. So we now have EMC Avamar for backups, and with this it means a chance to architect the backup solution the best possible way. So during the initial stage, I worked closely with our storage team to get the method that they chose to work. … Continue reading
PowerCLI to Generate Nested VM Folder Structure
We are currently starting to plan for a disaster recovery test, and the first part is configuring Site Recovery Manager (SRM). We are still in the middle of the infrastructure replacement, so we are starting from scratch with everything. So for SRM to work the best we need to have identical folder structures in both locations.… Continue reading
Cisco UCS PowerTools and PowerShell
As I mentioned in a previous post, we are upgrading our infrastructure and we are using Dell EMC VxBlock. So far this upgrade is going fairly smooth, but we are still at the very beginning of the process. So once I found out that the VxBlock was configured to contain UCS hardware, I began looking to see what Cisco had to offer for PowerShell modules to help manage the new hardware that we are getting. … Continue reading
The Prompt of a Different Color
In my work environment we are undertaking a major infrastructure upgrade. We are doing a total refresh of all of the virtual environment, and with this we are also setting up a new vCenter. With this it can get confusing with having multiple PowerShell ISE apps open and which vCenter I’m currently connected. … Continue reading
PowerCLI to get Virtual to Physical CPU Ratio
I was in a meeting today, and was asked, “What is the current virtual to physical CPU ratio?” I didn’t have an answer for this question, so I asked PowerCLI for the answer.
(get-cluster $ClusterName | Get-vm | Where Powerstate -eq “PoweredOn” | Measure NumCpu -sum).sum / (((Get-cluster $ClusterName | Get-vmhost).extensiondata.summary.hardware | Measure -Property numCpuCores -Sum).sum)
This will be a handy script that can be ran rather quickly. … Continue reading
What’s your (host)name?
While digging through Log Insight on a problem, I found a new one. A large majority of VMhosts were not configured with a proper hostname. This was also backup by the vCheck report that gets generated weekly. The hosts were configured with ‘localhost’ as the hostname, which makes this a huge pain when trying to follow the logs.… Continue reading
