Citrix has released an update on the cool tool XenDesktop site checker.
The XenDesktop site checker uses the XenDesktop Powershell SDK to enumerate XenDesktop 5 site brokers, services, hosts, assignments, catalogs, and provisioning tasks and schemes. It checks whether or not services are running and service instances are registered, and provides the ability to enable logging for each service. It also provides advanced management tasks that aren’t available in Desktop Studio, and provides detailed information about each component that it checks, and logs any script that is executed by the tool.
New Features in this release
Microsoft has released last week Update Rollup #3 for its System Center 2012 suite.
Here are the fixes they have solved in this update rollup pack:
What’s New in Personal vDisk 5.6.5
Citrix personal vDisk 5.6.5 includes a new registry and file-system architecture for
personal vDisks, which ensures better usability and application compatibility.
In previous releases, the part of a personal vDisk that stores applications, the .vhd file,
was mapped by default to the V: drive. In personal vDisk 5.6.5, the .vhd file no longer
requires a drive letter, so only one drive letter is used. By default, this is still P: and
stores the profile and other user data.
In addition, a new algorithm automatically adjusts the relative sizes of the two parts of
the vDisk (the space for applications and the space on P:) depending on how the vDisk
is used. For example, if a user installs several big applications on the personal vDisk so
space becomes limited, the application space is increased relative to the space on P:.
The overall size of the personal vDisk does not change. You can configure this feature.

I watched a webinar tonight about “Provisioning Services 6.0’s Coolest New Feature – vDisk Versioning” brought by Richard Nash. At the end of this great webinar (will post the link to the video and presentation when it comes available) Richard spent a few moments on how to update the drivers for the Provisioning Services target device.

When you have XenServer 6.0.2 installed before they pulled it from the download site (like me) you can choose to either re-install the new version (188.8.131.52) or to download the 2 hotfixes Citrix has released. I choose the latter and I‘ll show you how you can install and upload the hotfixes to your XenServer.
First of all download the 2 hotfixes (XS602E001 and XS602E002) from the Citrix download page. Save the 2 files to a location of your choice.
For the best results and the least problems it’s best to update the XenServer 1 update at a time. So select 1 update per run.
Open XenCenter and go to “Tools’ and “Install software update”.
Click “Next” on the first screen to select the update. Continue reading “Installing Citrix XenServer 6.0.2 hotfixes”
