Getting Started With PowerShell andPowerCLIIn this lesson you'll learn the basics of PowerShell and PowerCLI. You'll learn how to startthe PowerCLI console and PowerShell ISE, how to list available commands and view theirhelp.

Starting PowerCLI

After installation, PowerCLI can be started by double clicking the desktop icon labeled"VMware vSphere PowerCLI". This will open the PowerShell console and load all PowerCLImodules.

HOL-SDC-1607

Page 6HOL-SDC-1607

Using Powershell ISE

As an alternative to the simple console, you can use Powershell ISE script editor, whichprovides a better user experience. You can start the editor by double clicking its icon onthe desktop (1). The upper pane (2) is for viewing/editing script files, and the lower pane(3) is for running individual commands and displaying their output (an analog of thestandard PowerShell console).

HOL-SDC-1607

Page 7HOL-SDC-1607

Using Powershell ISE

During this lab you will execute various PowerCLI commands in the lower pane ofPowerShell ISE or in the PowerShell console. You can either type the commands yourselfor copy-paste them from the "Module7.ps1" files located on the desktop. The mostconvenient way to go through the lab is to open Module7.ps1 in the upper pane ofPowershell ISE. This file contains all commands you will call in this module. Eachcommand can be selected (1) and executed by pressing F8 (or "Run Selection" button(2)). Before executing a new command make sure the previous one is completed - youwill see "Completed" message (3) at the bottom of the console.

Listing Available Commands

Let's explore what we can do with PowerCLI. PowerCLI's snapins provide more than 500commands (called cmdlets in PowerShell) for managing vSphere, vCloud Air, SRM, vROps, and VUM. You can view the available PowerCLI commands by typing:

Get-VICommand

HOL-SDC-1607

Page 8HOL-SDC-1607

This will list all PowerCLI commands. As the list is quite large, you may want to narrow itdown to something more specific, for example all commands for managing VMs:

Get-VICommand *VM

Hint: You can use autocomplete for faster typing - just start typing the beginning of thecommand/parameter and press "Tab".

Connecting to vSphere

The first thing we need to do in order to manage our vCenter Server is to connect to it.This is done by using the Connect-VIServer command. Our vCenter is named "vcsa-01a"and here's how to connect to it:

Connect-VIServer vcsa-01a -User corp\administrator -Password VMware1!

The command will connect to the vCenter with the specified user's credentials.

Getting Help

If you are unsure how to use a specific cmdlet, you can easily view its help by typingGet-Help (or for short - just "help") and the name of the cmdlet:

help Connect-VIServer

If you want to see the full help with example usages of the cmdlet and parameterdescriptions you should open the full help of the cmdlet:

help Connect-VIServer -Full

If you want to see only the examples, you can use -examples switch like this:

help Connect-VIServer -Examples

You can also search for a specific word in the entire help archive. Let's try searching fora cmdlet that vmotions VMs:

HOL-SDC-1607

Page 9HOL-SDC-1607

help vmotion

The result contains the cmdlet we need - Move-VM. We'll use it later in this module.

Feel free to check the help of any cmdlet we demonstrate in this lab.

HOL-SDC-1607

Page 10HOL-SDC-1607

Using PowerCLI for reportingWith more than 100 Get-* cmdlets PowerCLI is also a powerful reporting tool. In thislesson, you'll learn more about this usage of PowerCLI.

Retrieving VMs

One of the most common things to do is list the VMs in your vCenter Server. This isuseful for browsing the inventory and reporting as well as for further processing ofspecific VMs (e.g. batch modification of VMs). You can retrieve all VMs with:

Get-VM

You can also retrieve one or more VMs by name. Try out the following:

Get-VM linux-CPU-Load-01a

Get-VM linux*

HOL-SDC-1607

Page 11HOL-SDC-1607

Retrieving specific properties of an object

When you call a cmdlet (like Get-VM) the result you get is an object or array of objects(in this case it's a VM object). To see what properties the object(s) have you can useGet-Member cmdlet like this:

Get-VM linux-CPU-Load-01a | Get-Member -MemberType property

This will list all the available properties of the VM object.

Note: Here we use a PowerShell functionality called "pipeline" (or "piping"). Get-Membercmdlet actually has a parameter called "InputObject" that accepts VM objects (as wellas all other PowerShell objects). Instead of retrieving our VMs, storing them in a variableand passing them to that parameter of Get-Member, we simply "pipe" the output of Get-VM to Get-Member. This way the output of the first cmdlet becomes the input of thesecond.

Then you can use PowerShell's 'select' command to retrieve only the properties youneed from resulting object:

Get-VM linux-CPU-Load-01a | Select Name, NumCPU, MemoryMB, PowerState, VMHost

HOL-SDC-1607

Page 12HOL-SDC-1607

Filtering report results

When the Get-* cmdlet has no parameter to filter the objects by the property you need,you can use PowerShell's 'where' command to filter the results from a cmdlet call:

Get-VM | Where {$_.Powerstate -eq "PoweredOn"} | Select Name, NumCPU, MemoryMB, PowerState, VMHost

Hint: $_ is a reserved powershell variable that holds the current object from the pipeline

HOL-SDC-1607

Page 13HOL-SDC-1607

Exporting report results to variousformatsTo present the data to your manager or another team or to transfer them to anothersystem that your company uses you need them formatted in some way.In this lessonyou'll learn how to export the data, generated by your PowerCLI reports to variousdifferent formats (txt, csv, xml, html).

HOL-SDC-1607

Page 14HOL-SDC-1607

Exporting to txt

Let's start with the most basic export - to txt file. To export your report to txt use Out-File PowerShell cmdlet:

Get-VM | Select Name, NumCPU, MemoryMB, PowerState, VMHost | Out-File c:\myPowerCLIReport.txt

Open the text file to check the result.

HOL-SDC-1607

Page 15HOL-SDC-1607

Exporting to csv

Now let's export the same data to csv format. We'll use Export-Csv cmdlet to do that:

Get-VM | Select Name, NumCPU, MemoryMB, PowerState, VMHost | Export-Csv c:\myPowerCLIReport.csv -NoTypeInformation

Check the result in the csv file

HOL-SDC-1607

Page 16HOL-SDC-1607

Exporting to xml

The next format that you'll export to is XML. The PowerShell cmdlet we'll use isConvertTo-Xml. Since this cmdlet returns XMLDocument object we need to call its Savemethod to write formatted data to file:

(Get-VM | Select Name, NumCPU, MemoryMB, PowerState, VMHost | ConvertTo-Xml -NoTypeInformation).Save("c:\myPowerCLIReport.xml")

Check the result in the xml file

HOL-SDC-1607

Page 17HOL-SDC-1607

Exporting to HTML

You can also export the data in HTML format by using ConvertTo-Html cmdlet. Since thiscommand just formats the data in HTML you also need Set-Content cmdlet to writeformatted data to file:

Get-VM | Select Name, NumCPU, MemoryMB, PowerState, VMHost | ConvertTo-Html | Set-Content "c:\myPowerCLIReport.html"

Now go to 'c:\' folder and open the report.

HOL-SDC-1607

Page 18HOL-SDC-1607

Adding formatting to the HTML page

If we want to make our HTML report look a bit better we can apply some styles on it likethis:

$a = "<style>"$a = $a + "BODY{background-color:Gainsboro;}"$a = $a + "TABLE{border-width: 1px;border-style: solid;border-color: black;border-collapse: collapse;}"$a = $a + "TH{border-width: 1px;padding: 5px;border-style: solid;border-color: black;background-color:SkyBlue}"$a = $a + "TD{border-width: 1px;padding: 5px;border-style: solid;border-color: black;background-color:PaleTurquoise}"$a = $a + "</style>"Get-VM | Select Name, NumCPU, MemoryMB, PowerState, VMHost | ConvertTo-Html -head $a | Set-Content "c:\myPowerCLIReport.html"

If you open the report now you'll see that it looks much better

Setting up and configuring a clusterIn the next few lessons you'll setup a small virtual environment of a fictional company -Nephosoft. You'll start with creating and configuring a cluster. Then you'll setupnetworking by creating and configuring a virtual distributed switch (VDS). At the endyou'll create several virtual machines based on a predefined specification, tag themaccordingly and then do a batch update of multiple VM specifications, based on theirtag. In this lesson we'll start with information on how to create and configure a clusterwith PowerCLI. You'll setup its EVC, HA and DRS settings.

Creating a cluster

To create a new cluster we'll use the New-Cluster cmdlet. We have to specify the nameand the location of the new cluster:

$cluster1 = New-Cluster -Name "Nephosoft Cluster 1" -Location "Datacenter Site A"

HOL-SDC-1607

Page 20HOL-SDC-1607

Configuring cluster's Enhanced vMotion CompatibilityMode

Now let's configure the cluster's enhanced vMotion compatibility mode to ensure CPUcompatibility for vMotion. To do that we'll first determine what EVC modes are supportedby our hosts:

$evcModes = Get-VMHost | Select MaxEVCMode

Now inspect the content of the $evcModes variable. Just type the name of the variable($evcModes) and its value will be printed to the screen. You'll notice that both hostshave the same evc mode.

Note: The EVC mode might be different from the one on the screenshot above, becauseit depends on the physical hardware that your lab environment runs on.

Let's set that EVC mode to the cluster to make sure that any other hosts that might beadded to the cluster in the future will have to match this EVC mode:

Set-Cluster $cluster1 -EVCMode $evcModes[0].MaxEVCMode

When you are prompted for confirmation - click yes.

Hint: Prompting for confirmation is good for interactive usage, however it is undesired inscripts since it will halt them. You can automatically confirm the operation by appending"-Confirm:$false" parameter to your cmdlet call.

HOL-SDC-1607

Page 21HOL-SDC-1607

Enabling HA on the cluster

The next step is to enable HA on our cluster to ensure that our VMs are protected incase of host failure:

Set-Cluster $cluster1 -HAEnabled:$true -Confirm:$false

Enabling DRS on the cluster and configuring DRS settings

Now let's enable DRS on this cluster and set its automation level to "manual" to make itgenerate recommendations for VM placement and migration (you can retrieve and apply

HOL-SDC-1607

Page 22HOL-SDC-1607

those recommendations with Get-DrsRecommendation and Apply-DrsRecommendationcmdlets):

Set-Cluster $cluster1 -DRSEnabled:$true -DRSAutomationLevel "Manual" -Confirm:$false

HOL-SDC-1607

Page 23HOL-SDC-1607

Moving hosts to the clusterIn this lesson you'll learn how to move our hosts to the already created cluster.

Moving hosts to the cluster

To move the hosts into the new cluster we need to put them in maintenance mode first.To put them in maintenance mode we have to shut down all the running VMs beforethat. So, let's retrieve all the running VMs and then stop them:

$vmsToStop = Get-VM | Where {$_.Powerstate -eq "PoweredOn"}

Stop-VM $vmsToStop -Confirm:$false

Now let's put the hosts in maintenance mode:

Get-VMHost | Set-VMHost -State Maintenance

Next we'll use the Move-Host cmdlet to move the hosts to the cluster:

Get-VMHost | Move-VMHost -Destination $cluster1

And at the end let's take the hosts out of maintenance mode:

Get-VMHost | Set-VMHost -State Connected

HOL-SDC-1607

Page 24HOL-SDC-1607

Setting up and configuring virtualdistributed switchIn this lesson you'll learn how to create a distributed switch and migrate hostnetworking to the distributed switch.

Creating a VDS (virtual distributed switch)

We'll start by creating a VDS with the New-VDSwitch cmdlet:

$vds = New-VDSwitch -Name "Nephosoft VDS" -Location "Datacenter Site A"

You can check the content of the $vds variable.

Adding ESX hosts to the VDS

Next step is to add both our ESX hosts to the distributed switch:

Add-VDSwitchVMHost -VDSwitch $vds -VMHost esx-01a.corp.local, esx-02a.corp.local

You can verify ESX hosts are successfully added in the distributed switch:

Get-VMHost -DistributedSwitch $vds

Creating distributed portgroups

Now let's create portgroups for the management, storage, vMotion and VM networkswith the New-VDPortGroup cmdlets:

HOL-SDC-1607

Page 25HOL-SDC-1607

$pgManagement = New-VDPortGroup $vds -Name "management"$pgvMotion = New-VDPortGroup $vds -Name "vMotion"$pgStorage = New-VDPortGroup $vds -Name "storage"$pgVM = New-VDPortGroup $vds -Name "VM"

You can verify that portgroups are successfully created:

Get-VDPortGroup -VDSwitch $vds

Migrating host networking to the VDS

We'll migrate our hosts' networking host by host. First we'll save both our hosts in avariable:

$hosts = Get-VMHost esx-01a.corp.local, esx-02a.corp.local

Then we'll migrate the networking for each one of them by using PowerShell's foreachloop. For each host we'll first retrieve its physical nics and then its management,storage, and vMotion VMKernel nics. Then we'll migrate them together by using the Add-VDSwitchPhysicalNetworkAdapter cmdlet, while specifying the distributed portgroups foreach VMKernel nic with the VirtualNicPortGroup parameter:

foreach ($vmhost in $hosts) {$pNics = Get-VMHostNetworkAdapter -VMHost $vmhost -Physical$vNicManagement = Get-VMHostNetworkAdapter -VMHost $vmhost -Name vmk0$vNicStorage = Get-VMHostNetworkAdapter -VMHost $vmhost -Name vmk1$vNicvMotion = Get-VMHostNetworkAdapter -VMHost $vmhost -Name vmk2Add-VDSwitchPhysicalNetworkAdapter -DistributedSwitch $vds -VMHostPhysicalNic $pNics -VMHostVirtualNic $vNicManagement,$vNicStorage,$vNicvMotion -VirtualNicPortGroup $pgManagement,$pgStorage,$pgvMotion -Confirm:$false

}

HOL-SDC-1607

Page 26HOL-SDC-1607

Migrating VM networking to the VDS

In the end let's migrate the VM networking as well. First we'll get the network adaptersof all the VMs:

$vmNetworkAdapters = Get-VM | Get-NetworkAdapter

Next we'll migrate these network adapters to the "VM" portgroup that we created in theprevious step:

Set-NetworkAdapter -NetworkAdapter $vmNetworkAdapters -Portgroup $pgVM -Confirm:$false

Now the network traffic of all the VMs is going through the VDSwitch.

HOL-SDC-1607

Page 27HOL-SDC-1607

Creating a VM and vMotioning itbetween the hostsIn this lesson you'll learn how to create a VM and vMotion it between the two hosts inthe cluster.

Creating a VM from scratch

Let's start by creating a VM with the New-VM cmdlet. We'll specify the VM's name, harddisk and memory size, the host and the datastore, on which we want to create it. Alsowe'll specify the portgroup for the VM network to be in the distributed switch, createdearlier. We'll place the VM on our NFS datastore, which is shared between our two hosts.

$vm = New-VM -Name 'jsmith' -VMHost esx-01a.corp.local -DiskGB 10 -MemoryMB 512 -Datastore ds-site-a-nfs01 -Portgroup $pgVM

Let's start that VM:

$vm | Start-VM

vMotioning the VM between the host

Now let's move the VM to the other host to make the workload more equally distributed:

Move-VM $vm -Destination esx-02a.corp.local

Note: If this is not the first module you're doing in this session, there is a chance thatyou may have some disconnected datastores in your environment. In this case you'llreceive an error that Move-VM is unable to access the virtual machine configuration. Ifthis happens you'll have to reconnect the NFS datastore on one of your hosts. To do sowe'll use Get-EsxCli cmdlet:

Retrieve EsxCLli for esx-02a.corp.local:

$esxCli = Get-EsxCli -VMhost esx-02a.corp.local

Verify NFS datastore isn't accessible:

$esxCli.storage.nfs.list()

HOL-SDC-1607

Page 28HOL-SDC-1607

...Accessible : false...

Disconnect NFS datastore:

$esxCli.storage.nfs.remove('ds-site-a-nfs01')

Reconnect NFS datastore:

$esxCli.storage.nfs.add('10.10.20.60', $false, $false, '/mnt/NFSA', 'ds-site-a-nfs01')

If needed repeat the same procedure for esx-01a.corp.local

Tip: Since Move-VM operation could take significantly long time, you may want to movethe VMs asynchronously and continue your work in the meantime. You can do that byspecifying -RunAsync parameter of Move-VM. Many other cmdlets that may take longtime to complete also support -RunAsync.

HOL-SDC-1607

Page 29HOL-SDC-1607

Creating multiple VMs and taggingthem appropriatelyIn this lesson you'll learn how to create multiple VMs with PowerCLI by a specificationsaved in csv file. You'll also tag the VMs according to the same specification.

Reviewing the specification

First of all let's review the specification that we'll follow when creating the VMs. Openthe 'vmspec.csv' file located on your desktop. For every VM we have the name, memorysize (in MB), disk size (in GB), department and type (user or server VM).

Reading the information from the csv file to an array

Now let's import that file to a PowerShell variable:

$spec = Import-Csv 'C:\Users\Administrator\Desktop\vmspec.csv'

Inspect the content of the $spec variable. You'll find out that it contains an array ofobjects (one object for each VM) and each one of these objects has a correspondingproperty for name, memory size, disk size, department and type.

HOL-SDC-1607

Page 30HOL-SDC-1607

Creating VMs based on the specification

Now let's create the VMs based on the specification. We'll use the foreach PowerShellloop again:

foreach ($vmSpec in $spec){

New-VM -Name $vmSpec.Name -MemoryMB $vmSpec."Memory size" -DiskGB $vmSpec."Disk size" -VMHost esx-01a.corp.local -Portgroup $pgVM}

Creating tag categories

Our next task is to tag our newly created VMs appropriately. To do that we'll start bycreating two different tag categories - "Department" and "Type":

New-TagCategory -Name DepartmentNew-TagCategory -Name Type

Creating tags based on the specification

Let's retrieve the unique department names first:

$departmentTagNames = $spec | select -Unique Department

Now let's create tag for each department:

HOL-SDC-1607

Page 31HOL-SDC-1607

foreach ($departmentTagName in $departmentTagNames){

New-Tag -Name $departmentTagName.Department -Category Department}

Next we have to do the same for the VM types:

$vmTypes = $spec | select -Unique Typeforeach ($vmType in $vmTypes){

New-Tag -Name $vmType.Type -Category Type}

You can check what tags were defined as a result by calling:

Get-Tag

HOL-SDC-1607

Page 32HOL-SDC-1607

Assigning tags to the VMs based on the specification

Now when we have the tags and tag categories properly defined it's time to tag the VMsappropriately. We'll use the New-TagAssignment to assign a tag to a VM:

foreach ($vmSpec in $spec){

$departmentTag = Get-Tag $vmSpec.Department$typeTag = Get-Tag $vmSpec.Type$vm = Get-VM -Name $vmSpec.NameNew-TagAssignment -Entity $vm -Tag $departmentTagNew-TagAssignment -Entity $vm -Tag $typeTag

}

HOL-SDC-1607

Page 33HOL-SDC-1607

Modifying multiple VMs based on theirtagIn this lesson you'll learn how to modify multiple VMs simultaneously with PowerCLI,based on their tags.

Updating VMs memory capacity based on their tags

A new application will be deployed in the Nephosoft sales department and that requiresthe memory on the user machines to be updated to 1GB. Now that we have our VMsproperly tagged it's easier to make a mass update of the VMs. Let's retrieve all the VMsfrom the sales department first:

$salesVMs = Get-VM -Tag sales

Next let's retrieve all the user VMs:

$userVMs = Get-VM -Tag user

Note: We cannot use "Get-VM -Tag sales, user", because that will return all the VMs areeither from the sales department, or user VMs and what we actually want is to get theVMs that are both from the sales department and are user VMs

Now let's select all VMs that have both tags assigned. For that purpose we'll useCompare-Object Powershell cmdlet:

$salesUserVMs = Compare-Object $salesVMs $userVMs -IncludeEqual -ExcludeDifferent -PassThru

Before we can update the VMs memory we need to make sure that they are all stopped:

$salesUserVMs | where {$_.PowerState -eq "PoweredOn"} | Stop-VM -Confirm:$false

Finally we'll update the VM's memory capacity with the Set-VM cmdlet:

Set-VM $salesUserVMs -MemoryGB 1 -Confirm:$false

HOL-SDC-1607

Page 34HOL-SDC-1607

Configuring and deploying an OFVtemplateIn this lesson you'll learn how you can apply configuration to an OVF template, whendeploying one.

Retrieve OvfConfiguration object

The OVF configuration in PowerCLI is represented as an OvfConfiguration object, whichcan be retrieved from an ovf file by Get-OvfConfiguration cmdlet. Note that you have tobe connected to a vCenter server in order to use this cmdlet, as it needs the connectionto parse the OVA properties.

$linuxMicroConfig = Get-OvfConfiguration -Ovf C:\OVF\linux-micro-01a\linux-micro-01a.ovf

Take a look at the object inside the $linuxMicroConfig variable. It contains one property,which points to the source ovf file and second, which is the actual configurable propertyfor the selected ovf file - NetworkMapping. When we take a look inside theNetworkMapping object we'll see that it contains single property VM_Network, which isthe only configuration that can be applied to that ovf tempalte.

Update OVF configuration

You can update the retrieved configuration just by assigning values to the objectproperties, matching the configurations you want to apply. In our case we will assignvalue to the "VM_Network"

$linuxMicroConfig.NetworkMapping.VM_Network.Value = 'VM'

Import vApp applying configuration

When you import your vApp you can apply its configuration using the new Import-VAppparameter "OvfConfiguration".

HOL-SDC-1607

Page 35HOL-SDC-1607

Import-VApp -Source 'C:\linux-micro-01a\linux-micro-01a.ovf' -OvfConfiguration $linuxMicroConfig -Name 'LinuxMicro' -VMHost 'esx-01a.corp.local'

Let's verify that configuration has been applied:

$linuxMicroVM = Get-VM 'LinuxMicro'$linuxMicroVM | Get-NetworkAdapter

As you can see, the vApp has been deployed with the correct network mapping.

Further ReadingThis lesson is for information purpose only and lists some of the more advanced featuresof PowerCLI, useful reading materials for both novice and advanced users as well asinformation for other PowerCLI related labs. Feel free to experiment with these if youlike.

Other PowerCLI related labs

HOL-SDC-1602 vSphere with Operations Management - Advanced Topics: Module 8 willintroduce you to the new PowerCLI cmdlets for managing vRealize Operation Manager.

HOL-HBD-1683 Managing Your Hybrid Cloud: Module 3 is all about managing vCloud Airwith VMware vSphere PowerCLI.

Accessing the entire vSphere API

Although PowerCLI offers more than 300 cmdlets for managing vSphere they don't coverthe entire functionality of the platform. Despite that you are still able to access all of thefunctionality by using the Get-View cmdlet. This special cmdlet is an access point to theentire vSphere API. The objects returned by the cmdlet are known as "Views" andrepresent an exact copy of the vSphere API objects. You can find more information aboutthese objects in the vSphere API Reference

Documentation:

http://pubs.vmware.com/vsphere-60/index.jsp

Using this cmdlet you will be able to write scripts directly against the API in an object-oriented manner.

Onyx for the Web Client

Onyx for the Web Client is a Fling that translates actions taken in the vSphere WebClient to PowerCLI.Net code. This Fling was the winning entry in last year’s 2014 FlingContest. It’s an update, of sorts, to the Onyx fling, as it allows for similar functionality inthe web client.

The Onyx for the Web Client Fling provides the ability to record actions taken in thevSphere Web Client and turn these actions into PowerCLI.Net code. The resulting codecan then be used to understand how VMware performs an action in the API and alsobetter define functions. You could also input the resulting code into search engines tofind the API documentation and information on how to use this area of the vSphere API.
