Register powershell snapin manually

I wanted to use the VMWare.vimautomation.core psssnapin in my scom discovery script.
But the snapin would not show up.
Earlier i had installed Powercli 6.0 and it does not have this snapin
So i uninstalled it and installed Powercli 5.5. But when the vcenter powershell was started it still showed 6.0 and the snapins would not show up.


 








 These are the steps I followed to manually register the snapin

As an example I will use the VMWare.VimAutomation.Core powershell snapin for .net 2.0.
Add the following registry key to your server.

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1\PowerShellSnapIns\VMware.VimAutomation.Core]
"PowerShellVersion"="2.0"
"Vendor"="VMware Inc."
"Description"="This Windows PowerShell snap-in contains Windows PowerShell cmdlets for managing vSphere."
"Version"="5.5.0.0"
"ApplicationBase"="C:\\Program Files (x86)\\VMware\\Infrastructure\\vSphere PowerCLI"
"AssemblyName"="VMware.VimAutomation.ViCore.Cmdlets, Version=5.5.0.0, Culture=neutral, PublicKeyToken=null"
"ModuleName"="C:\\Program Files (x86)\\VMware\\Infrastructure\\vSphere PowerCLI\\VMware.VimAutomation.ViCore.Cmdlets.dll"
"CustomPSSnapInType"="VMware.VimAutomation.ViCore.Cmdlets.Vim4PSSnapIn"

Copy the assembly files in modulename for powercli 5.0 to location

C:\\Program Files (x86)\\VMware\\Infrastructure\\vSphere PowerCLI

Open powershell and run command Add-PSSnapin Vmware.vimautomation.Core

Regular expression checker powershell

Simple powershell script to check your regular expression strings.

Increase VMware Vcenter server disk space using powershell

Increasing virtual disks in VMware is pretty easy and straightforward.
Mapping them to the right disk in your computer is hard. They have not direct correlation seen in the Vmware ui.
So its pretty much guesswork after checking the available diskspace in computer and matching it with the diskspace seen in VMWare.

This script matches the disks in VMware with the one in computer.
Increases the space
Extends all the partitions in your computer which have free diskspace.You shouldn't have diskpace lying around unused anyway ;)

Things you need.
Account which has rights on the VMware server. Account with rights on your computer.
VMware assemblies or powercli installed.

 If your script fails with and exception for SoapInterceptor
find the dll VMware.VimAutomation.Logging.SoapInterceptor.dll in your powercli install directory.
and add this line to your script after placing it in the right location.

[System.Reflection.Assembly]::LoadFrom("c:\temp\VMware.VimAutomation.Logging.SoapInterceptor.dll")

SQL server Reporting Services configuration manager does not open

This can happen due a corrupted wmi repository. If that is the case in your installation.

Find the file sqlmgmproviderxpsp2up.mof in your SQL installation directory on your server.

 In my case it was located in

C:\Program Files (x86)\Microsoft SQL Server\110\Shared

Then open command prompt as admin and navigate to the directory.

Then execute

mofcomp.exe sqlmgmproviderxpsp2up.mof

This will repair your repository  and you should be able to open the console.
