PowerCli One-liners for VMware.

This post covers some powercli "One Liners" which will help the VMware admin's to make the day smooth and simplify their day-to-day tasks on VMware.

Here we go... 

Query the vmware tools on all virtual machines

get-vm |% { get-view $_.id } | select Name, @{ Name=”Tools Status”; Expression={$_.guest.toolsstatus}}, @{ Name=”Tools Running Status”; E=$_.guest.toolsrunningstatus}}

Query the nic type of all virtual machines

Get-VM | Get-NetworkAdapter | Select-Object Parent,Type

Query the disk type of all virtual machines

get-vm | foreach-object -process {get-harddisk $_} | select-object storageformat | format-list

Get VMs with Memory Reservations

Get-VM | Get-VMResourceConfiguration | Where {$_.MemReservationMB -ne 0} | Select VM,MemReservationMBGet-VM | Get-VMResourceConfiguration | Where {$_.MemReservationMB -ne 0} | Select VM,MemReservationMB

Get VMs with CPU Reservations:
Get-VM | Get-VMResourceConfiguration | Where {$_.CpuReservationMhz -ne 0} | Select VM,CpuReservationMhz

Get VMs with Memory Reservations
Get-VM | Get-VMResourceConfiguration | Where {$_.MemReservationMB -ne 0} | Select VM,MemReservationMB

Get VMs with CPU Reservations:
Get-VM | Get-VMResourceConfiguration | Where {$_.CpuReservationMhz -ne 0} | Select VM,CpuReservationMhz

Retrieve VM snapshots older than three months

Get-VM | Get-Snapshot | Where {$_.Created -lt (Get-Date).AddDays(-90)} | Select-Object VM, Name, Created, SizeMB

Remove-Snapshot older snapshot
Get-VM | Get-Snapshot | Where {$_.Created -lt (Get-Date).AddDays(-120)} | Remove-Snapshot -Confirm:$false

VM-snapshot count
Get-VM | Where {(Get-SnapShot -VM $_ | Measure-Object).Count -gt 2} | Format-Table Name | Export-CSV C:\snapshot_counts.csv 

Get-VM | Format-Table Name, @{Label="NumSnapshots";Expression={(Get-Snapshot -VM $_ | Measure-Object).Count}}  

Find  RDMs in your environment

Get-VM | Get-HardDisk -DiskType "RawPhysical","RawVirtual" | SelectParent,Name,ScsiCanonicalName,DiskType

Mass storage Vmotion

Get-VM -Datastore <SourceDatastore1> | Move-VM -Datastore<TargetDatastore> -runasync

Take multiple vm's snapshots using single command 

Here all the VM's need to be dragged into single folder before running this on liner.

get-vm -location “floder_name” | New-Snapshot -Memory -Quiesce -Name <snapshot_name> -Description "Created $(Get-Date)"

 Disabling CDrom for Vmotions

(Get-VM -Location:(Get-Datacenter "NMC Tools")) | Get-CDDrive | Where { $_.IsoPath } | Set-CDDrive -NoMedia -Confirm:$false

 Find the VM's disk location by datacenter's.

get-datacenter "datacenter_name" | Get-VM | Select Name, @{N="Cluster";E={Get-Cluster -VM $_}}, `@{N="ESX Host";E={Get-VMHost -VM $_}}, `@{N="Datastore";E={Get-Datastore -VM $_}}

Check VMWare Tools Version

get-vm |% { get-view $_.id } | select Name, @{ Name=";ToolsVersion";; Expression={$_.config.tools.toolsVersion}}

Multipath status per Host within ClusterGet-Cluster "Acceptance" | Get-VMHost | where {$_.State -eq "Connected"} | Select Name, @{N="TotalPaths";E={($_ | Get-ScsiLun | Get-ScsiLunPath | Measure-Object).Count}}

Find all Dead Paths In a Datacenter
ForEach ($vmhost in (Get-Datacenter "The Netherlands" | Get-Vmhost | Sort)){ $deadpaths = Get-ScsiLun -vmhost $vmhost | Get-ScsiLunPath | where {$_.State -eq "Dead"} | Select ScsiLun,State; Write-Host $vmhost $deadpaths}

Find All LUN IDs in use on an ESX Server
Get-ScsiLun -vmhost esx01 -luntype disk | select runtimename | sort runtimename
