VMware View Scheduled Recompose

In this post we’ll go over writing a View PowerCLI script to schedule a recompose of a desktop pool.

If your like most VMware View administrators you’ll probably use linked clones, and know that now and again these clones will need recomposing to keep up to date with operating system patches or updates for embedded applications. If your organisation is like mine and operates on a 24 hours basis, getting downtime to perform a recompose can end up being headache and is usually scheduled for a unsavory hour.

Unfortunately scheduled tasks was not part of the View v5 release which i imagine left many people in my situation slightly disappointed. To get around this need for functionality, i turned to the View PowerCLI extensions and wrote a script to perform my desired tasks.

Below you will fine my script, along with one of my working examples that allows you to specify a linked clone pool to be recomposed from a specific virtual machine and snapshot at a defined time and date.

 

Script: Get-Pool -pool_id your-pool-id | Get-DesktopVM | Send-LinkedCloneRecompose -schedule ‘yyyy-MM-dd-23 hh:mm’ -parentVMPath “your-parent-vm-path” -parentSnapshotPath “your-snapshot-path

 

Example: Get-Pool -pool_id LC-EXT-H2F | Get-DesktopVM | Send-LinkedCloneRecompose -schedule ’2012-01-23 11:42′ -parentVMPath “/Hangar 1/vm/VMware View/Linked Clones/viewpocmlc” -parentSnapshotPath “/Base Windows 7 Image/Base Windows 7 Tweaked/Windows 7 with Basic Apps”

 

Below is an example desktop pool’s options which details the paths for -parentVMPath shown under Parent VM, and -parentSnapshotPath shown under Image.

VMware View Scheduled Refresh

In this post I will detail how to make use of the VMware View PowerCLI extensions. One feature I has hoping to see in the release of VMware View 5 was the ability to schedule tasks such as refreshing desktops or recomposing entire pools. Unfortunately this feature wasn’t added to View so i seeked my own solution. With View PowerCLI you can perform most if not all main functionality and better still, schedule when you went these commands to run. In this post the relevant commands for scheduling the refresh of a pool at a defined time are outlined.

Script: Get-Pool -pool_id your-pool-id | Get-DesktopVM | Send-LinkedCloneRefresh -schedule ‘yyyy-MM-dd hh:mm’

Example: Get-Pool -pool_id LC-EXT-H2F | Get-DesktopVM | Send-LinkedCloneRefresh -schedule ’2012-01-23 09:12′
