Update on System Center 2012 SP1 Update Rollup 2 (UR2) for Virtual Machine Manager

Posted on behalf of Carmen Summers

Greetings All,

This is Carmen Summers and I lead System Center Cloud and Datacenter Management Sustained Engineering.  I wanted to take the time to announce we are making an addition to System Center 2012 SP1 Update Rollup 2 and convey some important information regarding this addition. 

As of April 23rd we are adding Update Rollup 2 for System Center 2012 SP1 Virtual Machine Manager to System Center 2012 SP1 Update Rollup 2 release.  I have heard your feedback in the past that you all don’t prefer when we add content to Update Rollup releases in a delayed manner like we are doing and I agree with you.  We have been working very hard to avoid this over the past year, but in this circumstance we felt compelled to make an exception and add the content as opposed to making our customers wait until the next Update Rollup release window.   Please accept my apologies for this late addition and thank you in advance for your patience and understanding.

The master KB article for  System Center 2012 SP1 Update Rollup 2 has been updated to reflect the summary of issues and installation instructions for Update Rollup 2 for System Center 2012 SP1 – VMM.  You can refer to it here

Important actions for Update Rollup 2 for System Center 2012 SP1- Virtual Machine Manager

In order to install Update Rollup 2 package for System Center 2012 SP1-  Virtual Machine Manager, you will need to uninstall Update Rollup 1 for System Center SP1 – Virtual Machine Manager package from your system. 

– If you download Update Rollup 2 package for System Center 2012 SP1 Virtual Machine Manager from Microsoft Update Catalog and install Update Rollup 2 without un-installing Update Rollup 1  you should un-install Update Rollup 2 package for Virtual Machine Manager and then un-install Update Rollup 1 for System Center 2012 SP1 – Virtual Machine Manager via control panel. 

– If you are using WSUS to update System Center 2012 SP1 – Virtual Machine Manager and you have already installed Update Rollup 1 for System Center 2012 SP1 – Virtual Machine Manager then you will not receive Update Rollup 2 notification until Update Rollup 1 is uninstalled.

Why is this necessary?

When Update Rollup 2 is applied to a system which is running System Center 2012 SP1 Virtual Machine Manager with UR1, the installer does not patch files correctly. This is caused by the way UR 1 was packaged. As such the product fixes in UR1 are correct; it is the packaging of UR1 that causes this issue. If you do not need UR2, then you should continue to operate with UR1.   However, if you choose to stay on Update Rollup 1 for System Center 2012 SP1 Virtual Machine Manager and a later Update Rollup is released that you need to implement you will still need to remove Update Rollup 1 first.

We apologize for any inconvenience this causes your organization.  We have performed root cause analysis on the issue and have processes in place to prevent future recurrences of this situation.
