While checking the vmkernel logs on our VMware ESX Servers today, I ran into some errors referencing luns using a vml string. It looks something like this: vml.827149017315617. I would like to know what lun this error is referencing, but I prefer the LUN Path notation, e.g.: vmhba1:2:137. So I wrote this
In an attempt to make PeetersOnline.nl even better I am adding a Script Repository. It can be accessed through the button in the main navigation bar at the top of the site.
The Script Repository will soon hold all of my published Powershell scripts, formatted in a easy-to-use way, including a [...]
I have been looking at regular expressions in Windows Powershell recently. Although it seems very complex, the power of regular expressions (regex) is worth the effort! Think about server naming conventions for example. It’s easy for a human to recognise a server name that begins with a location code and contains a status [...]
Thanks to the VMware VI Toolkit 1.5, checking the NTP settings on all your VMware ESX Servers is as easy as a oneliner:
Get-VMHost | Sort Name | Select Name, @{N=”NTP”;E={Get-VMHostNtpServer $_}}
0. Installing
Installing or upgrading the VI Toolkit 1.5 is as easy as Next, Next, Finish. And using the new VI Toolkit shortcut on your desktop allows quick and easy access to the Toolkit. But what about running these cmdlets from your scripts or integrating it with other snapins? Read [...]
Just having a bit of fun with Powershell:

Why do computer nerds mix up Halloween and Christmas? Because 31 OCT = 25 DEC
I always mix up the commands used to convert integers to and from decimal, hexadecimal and octal in Powershell. That’s why I wrote these functions and put them in my profile:
# Description: Coverts a decimal into [...]
I have promised you I would post this script, so here it is!
This Powershell script generates an overview of any items that are not available to every ESX server in a VMware cluster. These items might prevent your vm’s being vmotioned by DRS or restarted by HA. Pretty serious [...]
I showed you before how to compare the datastores for two ESX Servers using the VI Toolkit. But ideally, one would like to compare all ESX servers in a cluster to ensure VMotion and HA compatibility.
So I started scripting and it turns out to be pretty simple: only 4 lines [...]
I’ve created another way to gather and display VMware Virtual Disk information with the Powershell VI Toolkit.
The attached script generates a csv-file with all Virtual Machines’ Disks, in which Datastore they are stored, the LUN IDs of the extents that make up this Datastore (in HEX) and the [...]
