#Quick On-liner to look through all VMs in a vCenter and unmount all of the connected CDs.

This is a quick script that will check your entire vcenter for VMs with the VMware tools ISO mounted and then attempt to unmounts that installer.
** Some Linux VMs will not successfully unmounts the tools installer so using the “eject” command inside the OS is needed.

#####Quick one-liner script
Import-Module -Name VMware.VimAutomation.Core
Connect-VIServer “my.vcenter.me -User “administrator@vsphere.local” -password “password”
get-view -viewtype virtualmachine -property ‘name’ -Filter @{‘Runtime.ToolsInstallerMounted’=’True’} | foreach{$_.UnmountToolsInstaller()}
Disconnect-VIServer -confirm:$false

#####Long method: This script will log into your vcenter, use a View command to instantly check all your VMs for the mounted installer and then uninstall it. If any VMs are found it will add the name to a “report” array. I left this $report array open ended so  you can add more fields like OS or cluster ID etc for additional references.   I ran this script on a vcenter with 6,000 VMs and it completed in under a second.  It took an additional three seconds to run the unmount command on five detected VMs.

$vcenter = “my.vcenter.me
$vcu = “administrator@vsphere.local”
$vcp = “password”

Connect-VIServer  $vcenter -User $vcu -password $vcp

$vmlist = get-view -viewtype virtualmachine -property ‘name’ -Filter @{‘Runtime.ToolsInstallerMounted’=’True’}
$report = @()
foreach ($vm in $vmlist) {
#unmount command
$vm.UnmountToolsInstaller()

#add to report with vcenter
$row = “” | select name,vcenter
$row.name = $vm.name
$row.vcenter = $vcenter
$report += $row
}

Disconnect-VIServer -confirm:$false

First: Thank you Mick Short for the idea.  When we think about adding vCPUs to a VM, we instantly think of the default, “adding sockets” and leaving core set to one.  This is “best practice” if you ask VMware and it allows DRS to make automatic decisions for CPU scheduling.

Unfortunately, software companies like to create weird licenses based on socket vs core of a server. Thus, comes the requirement of assigning more cores to our VM instead of sockets.

Here is a quick method to use to make this happen:  (VM has two sockets, three cores for six total vCPUs.)
$VMname= get-vm “VM1”
$TotalvCPU=6
$Cores=3

$spec=New-Object –Type VMware.Vim.VirtualMAchineConfigSpec –Property @{“NumCoresPerSocket” = $cores}
($VMname).ExtensionData.ReconfigVM_Task($spec)
$VMname | set-vm -numcpu $TotalvCPU

Next step is getting Set-VM updated to support Socket and Core values.

Quick Notes***
Ram and HardDisk Capacity numbers are in GB.   The bottom code to increase a VMs existing HardDisk has a WMI call to get the Drive letters (For Windows VMs).  This will help match Hard Disk to Drive letter before you issue the last command to expand it.

####### Edit your VM name here #######
$theVM = get-vm “MySuperCoolVM”

######Increase vCPU#######
$thevm | set-vm -numcpu “3” -confirm:$false

#######Increase RAM#######
$thevm | set-vm -memoryGB “8” -confirm:$false

#######Rename to old_X and move to old folder
$thevm | set-vm -name (“old_”+($thevm.name)) -confirm:$false
$thevm | move-vm -destination (get-folder “old”)

#######add new Drive to VM#######
$thevm |new-harddisk -capacityGB “50”

#######increase drive on VM#######
$thevm | get-harddisk | select name,capacityGB,filename

$report = @()
$temp = get-WmiObject win32_logicaldisk -Computername ($thevm.name)
foreach($b in ($temp | where {$_.drivetype -eq “3”})){
$reportrow = “” | select VMname, DriveLetter, VolumeName,CapacityGB, FreespaceGB,percentFree
$reportrow.vmname = $thevm.name
$reportrow.driveletter = $b.DeviceID
$reportrow.VolumeName = $b.VolumeName
$reportrow.capacityGB = “{0:N3}” -f ($b.Size / 1073741824)
$reportrow.freespaceGB = “{0:N3}” -f ($b.FreeSpace / 1073741824)
$reportrow.percentfree = [System.Math]::floor(($b.FreeSpace / $b.Size)*100)
$report += $reportrow
}
