How to create new portgroups in a VD Switch from a CSV-file. Very handy when adding several portgroups at one time.
$file = Import-Csv -path "c:\vlan.csv"
foreach ($row in $file)
{
New-VDPortgroup -VDSwitch dvSwitch_LAB1 -Name $row.name -VlanId $row.vlanid
}
This example uses invoke-webrequest to retrieve computer information from a company reporting webpage. Only text inside TD elements are stored in a array for future use and added to a PSObject.
function Get-ComputerInfo
{
[CmdletBinding()]
param
(
[parameter(
ValueFromPipeline = $true,
position = 0,
Mandatory = $true)]
[string]$computername
)
process
{
$Request = @{
'domain' = 'domain1.company.net'
'name' = $computername
}
$lab = Invoke-WebRequest -Uri https://reporting.company.net/searchcomputer.php -Body $Request -Method Post
$output = $lab.ParsedHtml.body.getElementsBytagname('TD') | select -expand innerhtml
if ($output[7] -match '\D\d\d\d\d\d\d\d')
{
$user = Get-ADUser -Identity $output[7] | select -ExpandProperty name
}
else
{
$user = "Unknown"
$output[7]= "Unknown"
}
$result = New-Object PSObject -Property @{
Computername = $output[0];
OU = $output[2];
IP = $output[6];
OS = $output[3];
LastUser = $output[7];
LastUSerFullName = $user;
LastSeen = $output[5];
Master = $output[4];
}
Write-Output $result | select computername, ou, ip, os, master, lastuser, lastuserfullname, lastseen
}#End Process

A short script to migrate VMs to a new cluster or host. Migrates one vm at a time to save network bandwith. After migration it upgrades Vmware tools to match current host version.
Takes a CSV file as input with VMs to migrate.

$file
)
$vms = Import-Csv $file
foreach ($vm in $vms)

I had some trouble with VMwaretools stopping on some machines and decided to automate restart och vmware tools. I wrote this script which takes a view parameter to view current status. If you start the script whitout the view parameter it will try to restart vmware tools.

(
[parameter(Mandatory = $false)]
[switch]
$view
)

if ($toolsvm -eq $null)
{
Write-Host "Nothing to fix"
Disconnect-VIServer vcenter -Confirm:$false
exit
}

If you need to create a new host with OP5 api you can use something like this.
Template, hostgroups and contactgroups are not mandatory and can be removed from hash table.
function new-op5host
(
[parameter(Mandatory = $true)]
[string]$hostname,
[parameter(Mandatory = $true)]
[string]$alias
)
{
$username = 'api_user$Default'
$password = "password"
$base64AuthInfo = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(("{0}:{1}" -f $username, $password)))
$hash = @{
file_id = "etc/hosts.cfg";
host_name = "$hostname";
address = "$hostname.domain.com";
alias = "$alias";
max_check_attempts = "3";
notification_interval = "5";
notification_options = "d", "r";
notification_period = "24x7";
template = "Win_hosts";
hostgroups = "Windows servers";
contact_groups = "Windowsservrar"
}
$jsonData = $hash | convertto-json
$result = Invoke-RestMethod -Method POST -ContentType "application/json" -Uri "https://op5.domain.com/api/config/host" -Body $jsonData -Headers @{ Authorization = ("Basic {0}" -f $base64AuthInfo) }

I needed a script to change desktop wallpaper for all users using the default one with an outdated company logo on. I came up with this startup script as a solution. Set $filesize to the size of the old wallpaper to only change wallpapers with same filesize. Use as logon script.
$filesize = 100593
$bg = Get-Item ("$env:USERPROFILE\appdata\Roaming\Microsoft\Windows\Themes\TranscodedWallpaper.jpg)
if ($bg.length -eq $filesize)
{
Copy-item "\\fileserver\UsrLogon\wallpaper\img0.jpg" "$env:USERPROFILE\appdata\Roaming\Microsoft\Windows\Themes\img0.jpg" -Force
Set-ItemProperty -path 'HKCU:\Control Panel\Desktop\' -name wallpaper -value "$env:USERPROFILE\appdata\Roaming\Microsoft\Windows\Themes\img0.jpg"
rundll32.exe user32.dll, UpdatePerUserSystemParameters
}
