VMware PowerCLI and ESXi Shell scripts

Small collection of VMware PowerCLI / Powershell scripts and onliners to save time re-typing them:

1. Get a list of all virtual machines with snapshots and save it to a csv file;

   #
   Get-VM | Get-Snapshot | Select-Object VM, Name, SizeMB, Created, Description | Export-Csv c:snapshots.csv
   #

2. Get a list of virtual machines, guest IP address, Datacenter, Cluster and Datastore they are running on;

   #
   Get-VM | select @{ Name = "Datacenter"; Expression = {Get-Datacenter -VM $_ }},`
                   @{ Name = "Cluster"; Expression = {Get-Cluster -VM $_ }},`
                   Name,`
                   @{ Name = "IPAddress"; Expression = { $_.Guest.IPAddress }},`
                   NumCPU, MemoryMb, ResourcePool, ProvisionedSpaceGB, UsedSpaceGB,`
                   @{ Name = "Datastore"; Expression = {Get-Datastore -VM $_ }},`
                   PowerState, Notes | Sort Name`
                   | Export-Csv "c:DC1.csv"
   #

3. Change Port Group on multiple VMs;

    $OldPortGroup = 'OLD_PG'
    $NewPortGroup = 'New_PG'
    Get-VM | Get-NetworkAdapter | where {$_.NetworkName -eq $OldPortGroup} | Set-NetworkAdapter -NetworkName $NewPortGroup -Confirm:$false

4. Enter/Exit Maintenance Mode;
   To enter Maintenance Mode, at the ESX console type:

   vim-cmd  /hostsvc/maintenance_mode_enter

   To exit Maintenance Mode type:

   vim-cmd /hostsvc/maintenance_mode_exit

5. Get a list of all virtual machines with a specific vNIC type, export to csv file;
   where {$_.Type -eq 'Vmxnet3'} – all VMs with VMXNET3 network adapter type
   where {$_.Type -eq 'e1000'} – all VMs with Intel E1000 network adapter type
   where {$_.Type -eq 'Flexible'} – all VMs with AMD 79C970 PCnet32 – LANCE NIC network adapter type
   where {$_.Type -ne 'Vmxnet3'} – any nic but VMXNET3

   #
   Get-VM | Get-NetworkAdapter | where {$_.Type -eq 'Vmxnet3'} | foreach ($_) {Write-Host $_.parent.name, $_.Name, $_.Type}
   OR
   Get-VM | Get-NetworkAdapter | where {$_.Type -eq 'Vmxnet3'} | Select @{N="VM";E={$_.parent.name}}, Name, Type | Export-Csv -Path c:nic.csv
   #

6. Find virtual machines with disks that need consolidation;

   Find VMs:
   Get-VM | where {$_.ExtensionData.Runtime.consolidationNeeded} | Select Name
   Find VMs and consolidate all:
   Get-VM | where {$_.ExtensionData.Runtime.consolidationNeeded} | %{$_.consolidatevmdisks_task()}
   #
   

7. List vmnic and vmkernel MAC addresses of the host;

   Get-VMHostNetworkAdapter | Select @{Name = "ESXi"; Expression = {$_.VMHost.Name}}, Name, Mac
   ESXi                         Name           Mac
   ----                         ----           ---
   host1.vstrong.info           vmnic0         00:25:b5:01:01:07
   host1.vstrong.info           vmnic1         00:25:b5:01:01:06
   host1.vstrong.info           vmk0           00:25:b5:01:01:07
   host1.vstrong.info           vmk1           00:50:56:71:1d:b9
   host1.vstrong.info           vmk2           00:50:56:7c:2a:d6
