Using vSphere Tags with PowerCLI

imageWith the new 5.5 R2 release of PowerCLI we introduced end-to-end support for the vSphere Tagging functionality. You can now automate Tag and TagCategory management, assign tags on objects and search for objects by tag. This blog post will give you an overview of the new functionalities and a couple of useful scripts:

  • One for exporting/importing of tags
  • One for converting the legacy custom attributes to tags

EVC with PowerCLI 5.5 R2–Part 2

In this previous post we talked about one of the great new features introduced in PowerCLI 5.5 R2 for configuring EVC, in this post we will continue to show how we can make configuring and using EVC easier with PowerCLI.

Compatibility checks

While configuring EVC on a cluster you will probably need to perform some compatibility checks. Here’s how you can automate them with a script.

Check host’s compatibility with a target EVC mode

EVC with PowerCLI 5.5 R2–Part 1

What is EVC?

Enhanced vMotion Compatibility (EVC) is a vSphere feature that you can enable on a specific cluster to maximize the vMotion compatibility of hosts within that cluster. EVC will make sure that all hosts in the cluster present the same CPU feature set to their virtual machines, even if the actual CPUs on the hosts differ. An EVC-enabled cluster can contain hosts with CPUs of different generations but only from a single CPU vendor.

What about performance?

EVC masks only those processor features that affect vMotion compatibility. Enabling EVC does not prevent a virtual machine from taking advantage of faster processor speeds, increased numbers of CPU cores, or hardware virtualization support that might be available on newer hosts.

What is “EVC mode”?

The EVC mode of a cluster reflects the minimum CPU generation that is supported by all hosts in that cluster. Continue reading

Enhancing the cmdlets from the previous version of PowerCLI we are now able to use PowerCLI for complete Tag management with the added New/Set/Remove Tag and TagCategory cmdlets.

Enable/Retrieve information on EVC Mode for Clusters

Adjustments to the Host and Cluster Cmdlets now allow for enabling, disabling and retrieving information for EVC Mode making automated build environments one step easier to accomplish.

Security policies for vSphere standard switch and port groups

Security policies can now be easily adjusted on vSphere standard switches and portgoups using the Get/Set-SecurityPolicy cmdelts.

Added support for PowerShell 4.0

PowerCLI can now be installed and used with the latest version of PowerShell at this time, PowerShell 4.0

Added support for IPv6

PowerCLI has now been updated to support vSphere servers configured with IPv6

Added statistical information

PowerCLI has been updated and we have added the ability to specify all supported types including clusters, datastores, etc and retrieve more statistical information via the Get-Stat and Get-StatType cmdlets.

64 bit Support

The New/Set-OSCustomizationSpec cmdlets have been updated to work in 64-bit PowerShell and no longer require running in a 32-bit PowerShell environment.

Even more updates

The above list is a high level list of the updates made to vSphere PowerCLI, for a more comprehensive list including all parameter and functional improvements, security enhancements, and deprecated features, see the vSphere PowerCLI Release Notes and the vSphere PowerCLI Change Log.
