How to update base Ardence VDisks

Sunil Kumar posted a good walkthrough of how you can update your base Provisioning Server images.

And i think alot of us struggled with a good way to perform this task. I think it is a pretty good guide i will however try to find the time to make a Video explaining the procedure.

This is Sunil Kumar’s howto:

To accomplish this perform the following steps in the Provisioning Server (PVS) console in XenDesktop.

Create a group for the client target devices in PVS and move target devices in the PVS group. We created a group called "Sales". The PVS target devices will have been created by the XenDesktop Setup Tool. Note this step is mostly for convenience.
In the vDisk create a class name and a type name. In our case we used a classname of "SalesClass" and a type name of "SalesType". These names can be whatever you want but must match the names used in later steps.
In one of the target devices in the PVS group set the class name as the name listed above. In our case the name is "SalesClass". Note that the client target devices do not have a type name.
Copy and Paste the class name for all the other target devices in the PVS group. Right-click on the target device and select Copy. Be sure to only copy the class name as selecting and pasting other choices could cause problems.
Make copy of the vDisk and rename it. Put this vDisk in the same vDisk repository already configured. This should be done from Windows Explorer and not the PVS console.
Add the new vDisk in the PVS console by right clicking on the PVS host, selecting "New vdisk" and select "Existing" to add this new vDisk.
In the copied vDisk set the class and type to the values used above. In our case it was "SalesClass" and "SalesType".
Increment the build number in the new vDisk. The build number is how PVS knows which vDisk is newer.
Set the new vDisk to private image mode. This is required to make changes to the vDisk.
Assign a desktop VM (target device) to the new vDisk. Be sure the new desktop VM is set to boot from virtual disk.
Boot the desktop VM and make updates. In this step you will make any updates you desire to the base image.
Shutdown the desktop VM and set to standard mode. We need to set the mode back to standard so it can be shared across multiple virtual desktops.
In the PVS console enable "Check for new versions of a virtual disk" in the PVS host "Options" tab. This will require the PVS streaming service to be restarted. This step only needs to be done once as this is set for each PVS host.
In the old and new vDisk check "Enable automatic updates" in the Disk Mode tab. This step only needs to be done once per vDisk.
To check for an update immediately, right click on PVS host and select "Check for disk updates" followed by "Check for updated virtual disks".
When the virtual desktop VMs boot they will be assigned the new vDisk. When users log off their virtual desktop, the virtual desktop VM will be restarted and will pull down the new updated vDisk image.
