Why New-VIProperty Matters!

Tweet
As you may have noticed, PowerCLI 4.1 has some cool new features for accessing the underlying SDK objects from within the PowerCLI objects.

Collect VMware ESX Host PCI Device Information

Tweet
Whenever you need to install a new box with ESX, there’s the struggle with matching physical ports to VMware devices.

PowerCLI: Reset CPU and Memory Limits

Tweet
Today I noticed a memory limit on a vm. After investigating my environment using the vEcoShell and the Community PowerPack, I found more vms with memory limits set. It turned out that there was a template which had the limit set. I could easily reset all limits using the GUI, but I thought I rather do it [...]

PowerCLI: Disable/Enable HA and DRS

Tweet
Before upgrading my Virtual Center 2.5 server to vCenter Server 4.0, I decided to temporarily disable HA and DRS. This is just a precaution taken to avoid waiting for cluster reconfigurations right after the upgrade. Because I hate doing things more than once by hand, I used PowerCLI for this.

Unattended upgrade of HP mgmt agents – Part 2

It’s been a year since I blogged about my script to perform an unattended upgrade of the HP management agents 8.1.1 on ESX 3.5 U3. After HP upgraded their management agents to version 8.2.0 some things changed. The installation procedure is now a 2 step process. First there’s a PreInstall_Setup.sh script which modifies some startup [...]

PowerCLI: Match VM and Windows harddisks – Part 2

Tweet
This is a follow up on a post I did a couple of weeks ago to create a mapping table between Windows- and VMware hard disks. In another previous post PowerCLI: Get WMI info from isolated guests, I showed you how to get WMI info from a guest without using the guest’s network. I used this [...]

PowerShell / PowerCLI linkage

Tweet
Since I started looking into PowerShell and PowerCLI, I gathered a couple of links which I found interesting and useful. I needed a way for them to be accessible anytime anywhere. Obviously the first thing that came across my mind was putting them on my blog somewhere.
