Getting ready for my first Open ConfigMgr 2012 class

8:40 pm in ConfigMgr 2012 by Kenny Buntinx [MVP]

Hi All,

I am preparing for my very first teach in an open class of ConfigMgr 2012. The material we’ll be using is the manual me and Kent Agerlund (Danish ConfigMgr MVP) wrote. We started writing at beta2 and have updated the material over the months up until RC1.

I am Busy updating it to RC2 as I am typing this, the course is nearly sold out, but still has a couple of seats (literally) left.

The course will take place at the JCAcademy in Louvain, if you want you can still register here: http://www.jcacademy.be/jca/be-en/course-details.page?Short=MOC213&r=freesearch&q=sccm&i=1

the course will cover Site installation, as well as migration. Followed by all the novelties of ConfigMgr 2012.

The course is open to new and seasoned ConfigMgr admins alike, but you’ll probably benefit the most from it if you already havea ConfigMg 2007 background.

Best regards,

Kim Oppalfens

SQL 2008 R2 failover cluster for system center: Lessons Learned (the hard way)

12:22 pm in SQL, SQL Reporting services, System Center by Kenny Buntinx [MVP]

I had assigned a task to install 5 SQL 2008 R2 cluster instances and on one of them had Analysis Services installed on a two node SQL Server 2008 R2 cluster (along with db engine).

Now I discovered that Analysis Services was not needed on one of the instances.

I thought : “No Problem , let’s remove” .

How do I remove this service from the cluster?

I tried the add/remove programs and command line option and both end up with the message: "The selected instance is clustered and cannot be removed as specified. To remove the selected instance, select "Remove Node" on the Installation Center or specify /Action=RemoveNode from the command line."

I tried removing one node hoping I could then uninstall from the only remaining node but still could not remove Analysis Services.

I’ve searched Google  Bing and discovered this article that explained that “You cannot add or remove features to a SQL Server 2008 or SQL Server 2008 R2 failover cluster”: Http://support.microsoft.com/kb/2547273

So I learned it the hard way. Think before you install a feature on a SQL Cluster , because once it is installed , there is no way back !!

Hope it Helps ,

SCVMM 2012 : Adding ESX 4.1(i) hosts will fail when using root account

10:23 am in SCVMM, SCVMM 2012, System Center, Vmware by Kenny Buntinx [MVP]

Maybe this is a very small blog post , but I think it could help some people out Smile

When you want to add your physical ESX 4.1 hosts with the root account and it does not succeed ( getting an access denied ) , it means that your hosts are in lockdown mode !

Switching off “Lockdown mode” gives you back the possibility to add your hosts with your root account.

Hope it Helps ,

CM12 : Issue with ASP.Net when installing the Application Catalog Website Point Role

7:24 am in CM12, ConfigMgr 2012, ConfigMgr V.next, dotnet, IIS, SCCM 2012, SCCM v.Next, System Center by Kenny Buntinx [MVP]

Yesterday I faced an issue at one of my customers when installing CM12 in a lab environment. I wanted to install the Application Catalog Website Point Role .

Scenario :

  • My CM12 site is installed and running
  • I am adding the necessary roles such as Fallback status point , Application Catalog website point and the Application Web Service Point.

To do that I added in IIS the ASP.net component as stated in the prerequisites here :

http://technet.microsoft.com/en-us/library/gg682077.aspx

SCCMprim018

Then I added the necessary roles and after looking in the appropriate log file , I discovered an error : “ Error: IIS Asp.net is NOT registered . Setup failed – Error 126. “

SCCMprim020

To solve this , you will need to navigate to "%systemroot%\Microsoft.NET\Framework\v.4.0\” and run “aspnet_regiis.exe –i “

Make sure that you register the latest version of Dot.net framework . In this case it is would be version 4 of dot net framework.

SCCMprim021

After restarting the CM12 services , the role reinstalled correctly without any issues .

Hope it Helps ,

Managing XenServer 6.0 with System Center Virtual Machine Manager (SCVMM) 2012 RC

9:21 am in Private Cloud, SCVMM, SCVMM 2012, XEN, XENSERVER by Kenny Buntinx [MVP]

I promised you that I will start blogging again more often. Here is a first series of blog posts.

At my current customer we will use hypervisors from VMware , Hyper-V and Xenserver  used in parallel because of various reasons. As we are in Private Cloud TAP and moving away from VMware the challenge will be the management (i.e. operational procedures and support). The management will be done by Microsoft’s System Center Virtual Machine Manager 2012.

SCVMM 2012 will be able to manage hypervisors all these different hypervisors from VMware , Hyper-V and Xenserver.

For that customer we are rolling out more or less 20 Citrix XenServers and therefore one of the platforms that will be managed by SCVMM2012.

The intention of this blog, is that you will be able to install and configure a Xenserver and hook it up to your SCVMM 2012 console .

1. Requirements

To allow Microsoft System Center Virtual Machine Manager 2012 managing a XenServer 6.0 or XenServer 6.0 Resource Pool, it is necessary to install the “SCVMM Integration Suite Supplemental Pack” within the XenServer(s).

SCVMM 2012 RC will support the following versions of XenServer by my knowledge:

2. Installation

The easiest way of installing the supplemental pack was during the initial XenServer setup. During the installation procedure the wizards asks if further supplemental packs should be installed. All you need to do is to insert the Supplemental Pack CD (or ISO) and follow the on-screen instructions.

Remark / Tip  : ** Do not try to install the pack afterwards as you get a lot of issues **

SupPack_1-300x225

SupPack_2-300x225

SupPack_3-300x225

3. Adding Citrix XenServers into SCVMM 2012

After install you can do the following checks from the SCVMM 2012 Machine to make sure it works before trying and connecting.

  1. Make sure that you can ping the host by the computer name or IP address. If you specified a computer name, make sure that the computer name is resolvable by DNS.
  2. Verify that the supplemental pack is installed correctly on the XenServer host. To do this, open a command prompt with Administrator privileges on the VMM management server, type the following command, where <HOSTNAME> is the name of the host, <ROOT USER> is the root user on the XenServer host, and <PASSWORD> is the password of the root user, and then press ENTER:
    winrm enum http://schemas.citrix.com/wbem/wscim/1/cim-schema/2/Xen_HostComputerSystem -r:https://<HOSTNAME>:5989 -encoding:utf-8 -a:basic -u:<ROOT USER> -p:<PASSWORD> -skipcacheck –skipcncheck
  3. If it is successful, the command returns information about the host computer. If the command is unsuccessful, the supplemental pack is either not installed or is not functioning correctly.

After the installation completed successfully we need to switch to the SCVMM Admin Console.The first part is to create a “Run As Account” within the “Create Run As Account Wizard”, as shown on the screenshot below.

The next step is to actually add and integrate the XenServer(s) with SCVMM 2012 using the following wizard: “Fabric Workspace ⇒ Servers ⇒ Add Resources (Ribbon) ⇒ Citrix XenServer Hosts and Clusters”, as shown on the screenshot below:

The XenServer(s) should now be listed as a available resource(s) within the “Fabric Workspace”, as shown below:

The only pity is that we cannot select an icon when it it’s a VMware or Xenserver ! Now there is no differentiation …

Hope it Helps ,
