Steps to Kick- Start Your VMware Automation with Power. CLIVirtualised environments can range pretty wildly in size; from one physical server in a small business or test lab with a few VMs, right up to large enterprises with hundreds or thousands of physical servers and seemingly limitless VMs. Whatever the size of your environment, as a good system administrator, you know that it’s important to configure it in a consistent manner, and automate as much as is reasonably possible. If you’re using VMware ESX / ESXi hypervisors and v. Center as the management software, then you already have access to a number of automation tools to assist with making your infrastructure function as smoothly as possible. These include VMware v. Sphere Power. CLI, VMware v. Sphere CLI and VMware v. Sphere SDK for Perl. In this article, I will be focusing on VMware v. Sphere Power. CLI, the automation tool supplied as a snapin for Microsoft’s Windows Power. Shell command line tool and scripting language, as well as 1. Getting Started. As I just mentioned, v. Sphere Power. CLI is provided as a snapin for Microsoft’s Windows Power. Shell, and so to use it you will need. NET Framework 2. 0 SP1 Windows Power. ![]() ![]() As mentioned in the previous section, an Integrated Development Environment (IDE) contains all of the things you need to develop, compile, link, and debug your programs.

You could get a pretty solid start just from this collection of writing advice from. Shell 1. 0 or 2. 0. Note. If you have Windows Power. Shell 2. 0, then I’d advise installing . NET Framework 3. 5 SP1, since you’ll then have access to the built- in Power. Shell ISE and cmdlets (such as Out- Grid. View). Of course, you should always refer to the VMware website for up- to- date system requirements. At the time of writing, Power. ![]() CLI is currently in version 4. Update 1, and is supported on the following 3. Windows Vista Windows XP SP2 Windows 2. Server SP2. Power. CLI itself will connect to and manage: VMware ESX 4. Update 1/v. Center Server 4. Update 1 VMware ESX 4. VMware ESX 4. 0/v. Center Server 4. 0 VMware ESX 3. VMware ESX 3i VMware Virtual. Center 2. 5 VMware ESX 3. Virtual. Center 2. There is also a separate Power. ![]() Shell snapin available for VMware Update Manager, which is the tool provided as an accompaniment to VMware v. Center to centrally manage the patching of ESX / ESXi hosts and guest virtual machines. This snapin has similar system requirements to the main Power. CLI tools, although it must be noted that these cmdlets require VMware v. Sphere Power. CLI 4. Update 1, and will only work with VMware Update Manager 4. U1. So, if your v. ![]() Center is the base 4. Both of the above sets of cmdlets can be found and downloaded from the VMware Power. CLI site, which is a great reference site for everything needed to get started with Power. CLI. If you really get stuck, there are experts waiting in the forums to answer any queries you may have. Bear in mind that when you’re getting started, it is likely that the majority of your questions will already have been answered in these forums, and a simple search will find those answers. Once all of the system requirements have been installed, the Power. CLI cmdlets can easily be accessed via the shortcut which the installer places on the desktop. Alternatively, if you’re already familiar with Windows Power. Shell, you may simply want to add the VMware snapins to your own session. If you’re unsure how to do this, you can just use the Add- PSSnapin cmdlet to make these cmdlets available to the current session, as shown below: Standard. Power. CLIcmdlets. Add- PSSnapin. VMware. Vim. Automation. Core. VMware. Update. Managercmdlets. Add- PSSnapin. VMware. Vum. Automation. For regular use, it would make sense to add these to your default Power.

Shell: This will open a text file containing the custom configuration to run each time a Power. Shell session is opened. If you receive an error that the profile file does not exist (i. Use the Connect- VIServer cmdlet to make the connection to VMware v. Center: 1. Connect- VIServerv. ![]() Center. Server. Name. Alternative credentials can be specified with the - Username and - Password parameters, if necessary. If the current credentials are not sufficient, then you may be prompted to enter more appropriate credentials via a standard Windows dialogue box. Steps to Kick Start Automation. Now that you’ve got your VMware automation tools configured and connected, it’s time to look at how to use them to get as much of your VM maintenance automated as possible. As you’ll see, I’ve broken this kick- start process down into bite- sized steps to make it easier to follow. These steps are individual stand alone operations, although they can be scripted to make powerful combinations. Taken together, all 1. Before you get started, I recommend downloading Alan Renouf’s excellent Quick Reference Guide (PDF), just in case you want to look up the details of any of the cmdlets I’ll be discussing. Reviewing and Configuring Virtual Machines. ![]() The reason virtual infrastructures are put together is primarily (and unsurprisingly) to run virtual machines, so a good place to start is with the Get- VM cmdlet, which can produce a simple inventory of all VMs currently found within VMware v. Center . Using the Get- VM cmdlet, and the standard Power. Shell Select- Object cmdlet, you can retrieve the particular properties that are of interest and use Export- CSV to export that data into the ever- useful CSV file format for further manipulation and distribution. Get- VM. There are a number of reasons why a virtual machine might not be permitted to VMotion; one of the most common is because it has a local CD- Rom drive attached. The below set of commands will iterate through all virtual machines, filter them based on whether the connection state of their CD- Rom drive is true, and return the name of the offending virtual machine(s): Get- VM. This means it becomes possible to both review and appropriately configure your VMs in a single step. In this instance, as well as retrieving the list of virtual machines where the CD- Rom is connected, it is very simple to extend the above command to automatically disconnect these CD- Roms, rather than carry out that task manually. Simply use the Set- CDDrive cmdlet to change the connection status of any connected CD- Roms which have been found: Get- VM. You can find out more about what cmdlets are available to adjust your VMs’ settings from the Power. CLI website, as mentioned earlier. Basic Capacity Information. The Power. CLI cmdlets can be used to give a quick overview of the number of hosts and VMs that exist within the Virtual Center; it could be useful to record these figures on a monthly basis so that the growth of the environment can be tracked over time. How about finding the average number of VMs per host in a cluster? Again, a useful figure to regularly record so as to observe what consolidation ratios are being achieved and to plan for future capacity needs, and a figure which Power. CLI can help you find. In the code below, we retrieve the ESX / ESXi hosts & VMs and observe their count; note the use of the $Default. VIServer variable, which is updated each time a connection is made to a v. Center. For the average number of VMs in each cluster, we find the total number of ESX / ESXi hosts and VMs and perform some basic maths to arrive at a figure. Note the use of some basic . NET . This would require individually selecting each host within the cluster, scanning it for new storage, and then moving on to the next host until all were complete – a process which quickly becomes frustrating. Thankfully, in v. Sphere 4. 0, VMware added a new option when right- clicking a cluster – Rescan for Datastores. Once initiated, this task would work through each host in the cluster and scan for new storage. However, if you are running a VMware version prior to version 4. Get- VMHost. Storage cmdlet has two parameters which you’ll find useful: - Rescan. All. Hba and - Rescan. Vmfs. Used in combination with the Get- Cluster and Get- VMHosts cmdlets, Get- VMHost. Storage can quickly become very powerful; for example, the command below will rescan for new storage on all of the hosts in Cluster 1: Get- Cluster'Cluster 1'. As I’ve already alluded to, VMware provide some fantastic VMotion technology within ESX and v. Center, which enables virtual machines to be transferred from one physical host to another with no downtime incurred for the virtual machine. To move all VMs from one host to another, use this simple one liner: 1. Get- VMHostesx. 01. Wrapping all that lovely technology into just one elegant step, the short script below will VMotion all of the virtual machines from one host in a cluster to random other hosts within the same cluster. Then we retrieve all of the hosts within Cluster 1, drop the source host from that list, and store the results in $clusterhosts. Next, we retrieve all of the virtual machines on the source host, storing them in $vms, and finally we cycle through each virtual machine, generate a random target host and move the VM to that target host. Storage VMotion Virtual Machines to a New SAN In a similar way to how the VMotion technology migrates a virtual machine from one physical host to another, it is also possible to move the disks for a virtual machine between datastores whilst the virtual machine remains online – this technology is known as Storage VMotion. This is even possible between different SANs, provided the hosts are configured to see storage on both old and new SANs and there is sufficient bandwidth to transfer the necessary data. Let’s say you have mapped out in, a CSV file, which datastore the disks for each virtual machine are moving to: We can bring that data into the Power. Shell session with the Import- CSV cmdlet, and then feed it into the Get- VM and Move- VM cmdlets to Storage VMotion those virtual machines to the new SAN. If you wanted to be really smart, you could use the Send- Mail. Message Power. Shell cmdlet to have it email you each time a Storage VMotion completes. Deploying Virtual Machines from a Template.
