Powershell Diagram vCenter

by Skylar PearcePowershell / vCenter - VMWare PowerCLI

This is a script that I got from someone else but have modified pretty heavily. This will use Powershell to diagram vCenter. This will connect to vCenter, pull a list of clusters and for each cluster it will create a Visio diagram and detail host, datastore and VM info. For this to run you need to have Visio installed. You also need these templates which apparently I’m not allowed to link to but you can find them pretty easy. The two non-standard ones I use are “EUC Visio Stencils 2018” and “Security and Systems Stencil.” You don’t NEED to use mine just make sure you update the section of the script that ties a stencil to a type of system. (its commented in there starting at line 69). The last thing needed is the PowerCLI module installed. You can see how that works here.

Script:

#Check for Creds and ask for them if they aren't found
if (!($Creds)) {$creds = get-credential -Message "Enter your vCenter Creds"}

$vCenter_Server = "vCenter_Server_Name"
Connect-VIServer -server $vCenter_Server -Credential $creds -force
$allclusters = Get-Cluster

    #// Connect its Begin to the 'From' shape:  
    $connectBegin = $shpConn.CellsU("BeginX").GlueTo($firstObj.CellsU("PinX"))  
    #// Connect its End to the 'To' shape:  
    $connectEnd = $shpConn.CellsU("EndX").GlueTo($secondObj.CellsU("PinX"))  
}

Powershell Install SCCM Client

by Skylar PearcePowershell / SCCM

There have been times where I have run into issues where the SCCM client doesn’t install on a new server or I am trying to finish a server setup quickly and I don’t want to wait for SCCM to do it automatically. Here is a little snip that will let you put a list of server or workstions into an array and it will copy the client locally and then run user powershell to install SCCM client.

Script:

#Check for Creds and ask for them if they aren't found
if (!($Creds)) {$creds = get-credential -Message "Enter your Domain Admin Creds"}

#Change this path, this should be pretty close to yours
$ClientPath = "\\SCCM_Server_Name\SMS_SITE\Client\ccmsetup.exe"

#List of Servers goes here
$servers = (
    "Server1",
    "Server2",
    "Server3" 
)

#This will clear any PSSessions
Remove-PSSession *

#Creates a PSSession for each server defined above and copies the most current client .exe locally
foreach ($server in $servers) {
    $s = New-PSSession -ComputerName $server -Credential $Creds
    Copy-Item $ClientPath -Destination "C:\ccmsetup.exe" -ToSession $s -Force
    Remove-PSSession $s
}

#Runs the client installer
$s = New-PSSession -ComputerName $servers -Credential $Creds
Invoke-Command -Session $s -ScriptBlock {
    cd C:\ ;
    .\ccmsetup.exe /mp:SCCM_Server_Name /logon SMSSITECODE=AUTO FSP=SCCM_Server_Name;
}
