VM's with Snapshots Running
Be aware that there's a bug in the way Get-Snapshot handles VM's in VI4, in that for the snapshot size it tends to report the maximum size a snapshot file could become, not the actual size that it is. As a result there is a workaround to found here - http://blogs.vmware.com/vipowershell/2010/09/snapshot-size.html. I've found that this reports smaller sizes for VI3 snapshots as well (which match the actual disk usage in the few occasions I've bothered to check).

To implement the Get-Snapshot size bug, download the workaround file from the link above. I've placed it in a sub-folder called lib, hence I've included it into my main script by using...
. .\lib\getsnapshotsize-1.ps1
...then I've just replaced Get-Snapshot with CalculateVMSnapshotsSizeMB

VM's Recently Created
I run the following script twice a week (via a scheduled task), to generate a report of VM's recently created, as a catch-all reminder to check VM backup's, monitoring, etc etc have been set-up as required. The number of days history it searches through can either be altered in the script (the $days parameter), or passed as a command line parameter when run as a scheduled task.
The script borrows heavily from http://get-admin.com/blog/how-to/vmware/powercli-get-every-vm-added-to-vcenter-in-the-last-30-days/, which is where the real genius of the script comes from.
I use a username and password file for credentials, see Store Password Securely for more info, plus a CSV with a list of vCentres in (one column with a heading of "vc").
$UserFile = "User.fil"
$PassFile = "Pass.fil" # Encrypted file to store password in

Add Attributes to VMs from CSV
You have the option in vCentre to create your own custom attributes to any of the standard objects. This can be incredibly useful if you have a sprawling estate of VM's to manage for various different parts of your company, as you can record information like Owning Dept., Product Family etc against your VM's. The only problem is that you then have fields that have to be manually updated (that and the fact that the info is only held in a VM's vCentre database records, not its VMX, so if you have to re-add a machine to vCentre, you'll lose the custom attributes you populated.
The following script allows you to update VM attributes from a CSV file (which can be very convenient if you've just deployed 20 VM's for a project).

ESX Discovered Networks Hint
This function provides the discovered network hints for the network interface its passed. Bear in mind that its just a hint, for an ESX to be aware of a particular vLAN it needs to see traffic. If there's no traffic it will show nothing.

ESX BIOS, NIC and HBA Driver Versions
Getting BIOS, NIC and HBA driver versions is dependant on what's reported to the ESX by the hardware vendor's CIM provider. This script was written using various HP servers and may well only work for them.

Daily ESX Up/Down Check
Simple script that runs every morning just before I start work to provide a basic sanity check email to glance through over the first tea of the day.
See the following page for details on how to Store Password Securely (as I have done, loaded though the files specified by $UserFile and $PassFile in the script below).

# ESX Checker
#
#############################################################################################
#
# By Simon Strutt
#
# Version 1 - Aug 10
# - Initial creation
#
# Version 2 - Oct 10
# - Fixed VIServer handling (was never good but stuffed by upgrade to PowerCLI 4.1)
# - Improved email in case of vCentre connection failure
#
# Version 2.1 - Nov 10
# - Minor text changes
#
# Version 2.2 - Nov 10
# - Added InvalidLogon catch to vCentre logon to prevent a/c lockout
#
# Version 3 - Dec 10
# - Truncated displayed ESX hostname (stripped domain)
# - Added "since <datetime>" info to ESX's that aren't in a good state
# - Bugfix: Incorrect email config used when VC list config file load failed
#
# Version 3.1 Jan 11
# - Workaround: Powershell/MS DateTime object returns incorrect (US) date format
#
# Version 3.2 Jan 11
# - Bugfix: Extraneous " hrs" on end of v3.1 fixed datetimes

ESX Storage Events
Creates a CSV of storage events (eg path up/downs). Useful in order to be analyse storage events, for example if you need to tally up to SAN logs etc. Note the get-VIEvent is limited to 1000 results, which will typically get 1 - 2 days worth depending on your infrastructure. To get a longer history would require multiple calls to get-VIEvent using the -Start and -Finish parameters

ESX Datastore to LUN Mapping (ESX3)
Its bizarrely difficult to be able to map VMware presented datastore names to the underlying LUN's, despite the fact that its readily available via the VI Client. The following was adapted from the work of Catman found in this forum thread - http://communities.vmware.com/thread/240466#240466. As I expect to maybe want some of the other fields available during the working my notes from working through this are to be found here
# Thieved and adapted from the good work by catman...
# http://communities.vmware.com/thread/240466#240466
$objESX = Get-VMHost "My_ESX*"
# Get .NET views for host and storage system
$objViewESX = Get-View -id $objESX.id
$objViewESXstorageSys = Get-View -id $objViewESX.ConfigManager.StorageSystem
# Get FC HBAs
$HBAs = $objViewESXstorageSys.StorageDeviceInfo.HostBusAdapter | Where-Object {$_.Key -like "*FibreChannelHba*"}
foreach ($hba in $HBAs) {
# Enumerate LUNs
$LUNcount = $objViewESXstorageSys.StorageDeviceInfo.MultiPathInfo.Lun.Length
for ($LUNidx = 0; $LUNidx -lt $LUNcount; $LUNidx++ ) {
$objScsiLUN = $objViewESXstorageSys.StorageDeviceInfo.MultiPathInfo.Lun[$LUNidx]
# Enumerate paths on LUN
$PathCount = $objScsiLUN.Path.Length
for ($PathIdx = 0; $PathIdx -lt $PathCount; $PathIdx++) {
$objSCSIpath = $objViewESXstorageSys.StorageDeviceInfo.MultiPathInfo.Lun[$LUNidx].Path[$PathIdx]
# Only care about one path, active on current HBA
if (($objSCSIpath.PathState -eq "active") -and ($objSCSIpath.Adapter -eq $hba.Key)) {
# Now get the disk that we want
$objSCSIdisk = $objViewESXstorageSys.StorageDeviceInfo.ScsiLun | Where-Object{ ($_.CanonicalName -eq $objScsiLUN.Id) -and ($_.DeviceType -eq "disk") }
# Now get the datastore info for disk
$MountCount = $objViewESXstorageSys.FileSystemVolumeInfo.MountInfo.Length
for ($MountIdx = 0; $MountIdx -lt $MountCount; $MountIdx++ ) {
if ($objViewESXstorageSys.FileSystemVolumeInfo.MountInfo[$MountIdx].Volume.Type -eq "VMFS" ) {
$objVolume = $objViewESXstorageSys.FileSystemVolumeInfo.MountInfo[$MountIdx].Volume
$ExtentCount = $objVolume.Extent.Length
for ($ExtentIdx = 0; $ExtentIdx -lt $ExtentCount; $ExtentIdx++ ) {
$objExtent = $objVolume.Extent[$ExtentIdx]
# Match extent name to disk name
if ($objExtent.DiskName -eq $objSCSIdisk.CanonicalName) {
