how to get the correct Virtual Disk for a VMware vm

8. March 20188. March 2017 by Burkard Josh

Some times I have the problem, I need to resize or delete a VMware virtual disk, but I only know the guest’s drive letter. In vm’s where there are only one virtual disk, or where each virtual disk has a different size, this isn’t a problem. but if you have a vm with multiple virtual disk with exactly the same size, you can’t compare it between the guest Disk Manager and the virtual disk sizes. if your vm has more than one SCSI controller, the problem will increase.

Windows Disk Manager	VMware VM settings

I searched long time to solve this problem, but I couldn’t find an easy solution for this. so I wrote this PowerShell script:

<#
.SYNOPSIS
    This script will return informations about virtual disks and windows disk allocation

.DESCRIPTION
    This script will return informations about virtual disks and windows disk allocation

.PARAMETER vCenterName
    defines the fqdn of the vCenter

.PARAMETER vmName
    defines the name of the vm (like naming in vCenter, not the fqdn / dns name)

.PARAMETER vmCred
    enter credentials to connect to the guest vm

.EXAMPLE
    $vmCred = New-Object System.Management.Automation.PSCredential ('domain\username', ( ConvertTo-SecureString 'YourSecretPassword' -AsPlainText -Force ) )
    .\ALL-OPR-get-VMDiskInfos.ps1 -vCenterName 'vcenter.domain.local' -vmName 'VMName' -vmcred $vmCred

add domain groups to vSphere ESXi 5 with PowerCLI

12. September 201328. June 2013 by Burkard Josh

With PowerCLI, you can add AD authentication to a single managed ESXi Host. For this you need to add your ESXi-Host to the AD (line 9) and then add permissions (line 11):

$VMHost        = "hostname.domain.local"
$HostPW        = "yxz"
$DomainAdmin   = "DomainAdmin"
$DomainPW      = "yxz"
$ADGroup       = "domain\DomainGroup"
$Domain        = "domain.local"

Add-PSSnapin VMware.VimAutomation.Core

Connect-VIServer $VMHost –User root –Password $HostPW
Get-VMHostAuthentication -VMHost $VMHost | Set-VMHostAuthentication -Domain $Domain -Username $DomainAdmin -Password $DomainPW -JoinDomain -Confirm:$false

Get-VMHost $VMHost | New-VIPermission -Principal $ADGroup -Role "Admin"

Disconnect-VIServer $VMHost -Confirm:$false

$VMHost = "hostname.domain.local"

$HostPW = "yxz"

$DomainAdmin = "DomainAdmin"

$DomainPW = "yxz"

$ADGroup = "domain\DomainGroup"

$Domain = "domain.local"

Add-PSSnapin VMware.VimAutomation.Core

Connect-VIServer $VMHost –User root –Password $HostPW

Get-VMHostAuthentication -VMHost $VMHost | Set-VMHostAuthentication -Domain $Domain -Username $DomainAdmin -Password $DomainPW -JoinDomain -Confirm:$false

Get-VMHost $VMHost | New-VIPermission -Principal $ADGroup -Role "Admin"

Disconnect-VIServer $VMHost -Confirm:$false

sometimes line 11 will fail, then you have to wait for domain replication and repeat it.

List VMTools Status with vCheck

28. June 201325. February 2013 by Burkard Josh

i like vCheck to daily report my virtual environment status. But a lot of our guest systems are not in my responsibility, so the VM Tools are not uptodate or aren’t installed.

i wroted this plugin for vCheck:

$Title = "VMs by VM Tools status"
$Header = "VMs by VM Tools status : $($VMToolsVersions.count)"
$Comments = "The following Operating Systems are in use in this vCenter."
$Display = "Table"
$Author = "Josh Burkard"
$Version = 1.0

# Start of Settings
# —- VM Guest OS Pivot Table —-

$VMTools = get-vm | % { get-view $_.ID } | select Name, @{ Name="hostName"; Expression={$_.guest.hostName}}, @{ Name="ToolsStatus"; Expression={$_.guest.toolsstatus}}, @{ Name="ToolsVersion"; Expression={$_.config.tools.toolsVersion}} | sort-object ToolsVersion

$VMToolsVersions = $VMTools | Where { $_.ToolsStatus -ne "toolsOk" } | sort ToolsVersion -desc

If (($VMToolsVersions | Measure-Object).count -gt 0 -or $ShowAllHeaders) 
{
	$MyReport += Get-CustomHeader "VMs by VM Tools status : $($VMToolsVersions.count)" "The following VM Tools Status are not OK or old."
	$MyReport += Get-HTMLTable $VMToolsVersions
	$MyReport += Get-CustomHeaderClose
}

$Title = "VMs by VM Tools status"

$Header = "VMs by VM Tools status : $($VMToolsVersions.count)"

$Comments = "The following Operating Systems are in use in this vCenter."

Installing HP ESXi Offline Bundle for VMware ESXi 5.0

16. February 201216. February 2012 by Burkard Josh

The steps to install the offline bundle for VMware ESXi 5.0 has changed from VMware ESXi 4.X. The vihostupdate command used in ESXi 4.X does not work against ESXi 5.0 hosts.

1. Download the bundle.zip.

Either Google “HP ESXi Offline Bundle for VMware ESXi 5.0” or go to www.hp.com → Support & Drivers → Drivers & Software → Search for the server model (e.g. ProLiant BL640c) → Select the server series → Select operating system = VMware ESXi 5.0 → Find “* RECOMMENDED* HP ESXi Offline Bundle for VMware ESXi 5.0 → Download read more

Clone your Active Directory in 18 minutes using VMware

10. October 201110. October 2011 by Burkard Josh

Anyone out there who runs a successful Microsoft Windows Active Directory, knows that it is pre-eminently useful to have a test environment that very nearly represents your production environment…to do…you know…testing!

I thought I would give that a try, and here’s what I came up with:

Shutdown and clone a Virtual Domain Controller with a 50GB disk drive, 10 minutes.
Attach the virtual DC to a totally private network, visible only to other virtual machines on the same box, 15 seconds.
Restart the cloned DC, 1 minute.
Seizing FSMO roles from Domain Controllers that aren’t in this private network, 3 minutes.
Sit back in wonder, 45 seconds.

These simple steps aren’t completely error free. Because the DC I chose was a replication partner with a bunch of other DCs and Active Directory Sites, it was necessary to do some tweaking to remove the “defunct” Domain Controller properties from the Active Directory. That process is documented well, here: Remove old Domain Controller Settings from FRS and the Domain. If you have a lot of Remote Domain Controllers and you only need your clon e for a little test, it may be to expensive to remove all remote DC’s. In this case you can create this registry value, so your clone isn’t waiting anymore for replication partner: read more

Shutdown full VMware datacenter on UPS failure

13. August 201111. July 2011 by Burkard Josh

To shutdown a VMware datacenter on UPS failure i found a PowerShell script, which i modified:

The script will shutdown the desired VMware datacenter, but it will ask you first, if you are sure. If you like to run the script in silent mode, you can run it with parameter yes.

You have to define the hostname of your VirtualCenter and the name of the datacenter. To run the script, you will need, to have VMware PowerCLI installed.

You can dowload the script shutdownESX.ps1 (right-click -> Save As) or copy/paste it from here:

# ===========================================================================================

#                      .\shutdownESX.ps1 yes   --&gt;   shutdown the datacenter
#					                                 without any question
#
#  Description:        - Shutdown the defined VMware Datacenter
#                      - you have to set this variables:
#                          - VirtualCenter
#                          - DataCenter
#
#  The script will not run well, if the VirtualCenter server is running as VM in the same
#  data center.
#
#  I’m sure I don’t need to tell you that you need to be extremely careful when testing
#  this script as one false move could shut down everything !
#  Please test this to make sure it works first !

# Script Information

# Title: shutdownESX.ps1

# Author: Josh Burkard

# Date: 11.07.2011

# Requirements: Windows Powershell and the VI Toolkit

# Usage: .\shutdownESX.ps1

# .\shutdownESX.ps1 yes --> shutdown the datacenter

# without any question

# Description: - Shutdown the defined VMware Datacenter

# - you have to set this variables:

# - VirtualCenter

# - DataCenter

# The script will not run well, if the VirtualCenter server is running as VM in the same

# data center.

# I’m sure I don’t need to tell you that you need to be extremely careful when testing

# this script as one false move could shut down everything !

# Please test this to make sure it works first !

ESXi 4.x: change the blocksize for a partition

1. June 201111. May 2011 by Burkard Josh

The ESXi 4.x installer utilizes the default blocksize of 1MB when creating VMFS volumes, allowing for storage of files 256GB and under. This default VMFS Datastore cannot be easily reformatted with a higher blocksize as it contains the Service Console VMDK file. But to store files greather than 256 GB (ex. VMDK), you have to use a blocksize greather than 1 MB on your partition. If you use your system-partition for saving VMDK-Files greather than 256 GB, you have to change the blocksize of your system-partition. Unfortunately VMware doesn’t give you the possibilty to do this during the installation. So you have to do this with a trick after the installation: Install the VMware ESXi 4.x host as always. After the installation follow this steps:

Press the Funktion-Key F2

Logon with your root-account.

Select Troubleshooting Options.

Select Enable Local Tech Support. After you enabled the local Tech Support, press two times the Key ESC, to exit to the Default Screen.

Press the Key-Combination ALT+F1 to enter the local Tech Support. You have to logon again on the console screen. After you loged in, run the follow command:

esxcfg-scsidevs –m

1	esxcfg-scsidevs –m

You will receive the informations about all installed Drives:

Now run this command:

vmkfstools –C vmfs3 –b &lt;BLOCKSIZE&gt; datastore &lt;DRIVE-ID&gt;

1	vmkfstools –C vmfs3 –b <BLOCKSIZE> datastore <DRIVE-ID>

For <BLOCKSIZE> use the value from the next table. For <DRIVE-ID> use the value received from the last command (marked yellow in example):

block size	maximum file-size on vmfs3
1 MB	256 GB
2 MB	512 GB
4 MB	1 TB
8 MB	2 TB

The process did run for around 20 seconds on my 1 TB disk. After succesfull running, press the Key-combination ALT+F2, to exit to the default window. Please disable now the Local Tech Support and make a reboot.
