Installing hyper-v inside a vm on Windows Server 2012

4:07 pm in Uncategorized by alkin

 

For a test setup I needed to install a Hyperv inside a vm running Windows server 2012. I did some googling and found the following post http://www.aidanfinn.com/?p=10175 from Aidan saying that its possible on Win 2008.

So I wanted to give it a try but it failed saying that a Hypervisor was already running

Apparently in Windows 2012 Microsoft wont let you install the Hyper-V role inside a VM. Bummer!

So I gave it another try using Powershell and hoping to bypass the validation check by using the following command: “Install-WindowsFeature –Name Hyper-V -ComputerName hyperv01-IncludeManagementTools –Restart” but it failed as well, with same error!

The only solution was to ping my good friend Mike Resseler who told me to try the following powershell command:

“DISM /Online /Enable-Feature /FeatureName:Microsoft-Hyper-V" which let me install Hyperv just fine!

and the following will enable the Hyperv Management console: “DISM /Online /Enable-Feature /FeatureName:Microsoft-Hyper-V-Management-Clients

Thanks,

Alex

New KB for OpsMgr Management servers or assigned agents unexpectedly appear as unavailable in the Operations Manager console in Windows Server 2003 or Windows Server 2008

7:25 pm in Uncategorized by alkin

Microsoft just released a new hotfix to deal with ghost agents or agent that are grayed out for an unknown reason. Sometimes it can happen that an agent unexpectedly appear as unavailable without any real reason. We call this ghost agents

The workaround was to delete the health service state directory on the computer (root management server, management server, or agent) that is affected. That way the database will be rebuild.

But Microsoft has now identified this problem as this issue occurs because the database that is used by the health state is corrupted. This database corruption is caused by an issue in the storage engine of the jet database that is hosted on Windows. This is a problem in the Microsoft products and not in OpsMgr. So you need to apply the hotfix to fix the storage engine.

You can download the KB here http://support.microsoft.com/kb/981263 

Notice that this hotfix applies to Windows Server 2008 but not Windows Server 2008 R2.

Hope this helps,

Windows Server Operating System Management Pack for Operations Manager 2007

6:55 am in Uncategorized by alkin

Microsoft just released an update for the windows server mp. They now support Windows 2008 R2 ! Another nice thing is that finaly you can also display the logical disk size in MB’s! It was so damn stupid of Microsoft to only dispplay  the size in Bytes.

You will need to persononalize the logical disk state view because it’s not enabled by default

The September 2009 release (version 6.0.6667.0) of the Windows Server Operating System Management Pack includes the following changes:

· Support for Windows Server 2008 R2, including new classes to represent Windows Server 2008 R2 systems specifically.

· The intervals for some discoveries have been changed to reduce CPU usage. For details, see Objects the Windows Server Operating System Management Pack Discovers.

· Added Logical Disk Fragmentation Level monitors for Windows Server 2003 and Windows Server 2008.

· Disabled the following rules and monitors for Windows Server 2008 because the events needed are in Windows Server 2003 only.

· Duplicate computer name was detected

· Windows Activation State

· Disk Group Failed

· Disk Group Auto Import Failed

· Volume Not Started

· Run WMIAdap

· Fixed the summary details for the Performance History (Percent Processor Time) report to indicate that the object type is Windows Server 2003 operating system rather than Windows Server 2003 processor.

· Fixed the Performance History (Percent Interrupt Time) report to use a rule that targets the operating system rather than the processor.

· Changed the data source for discoveries from System.Scheduler to System.Discovery.Scheduler to avoid performance issues.

· Changed the Logical Disk Availability monitor to use a Run As profile with administrative privileges to enable it to run in a low-provilege environment.

· Modified logical disk discovery to exclude mount points, because numerous rules use performance counters that are not applicable to mount points.

· Fixed an issue in which an alert could be generated for Windows Activation too early.

· Addressed an issue that was causing some discoveries to not show up correctly in the authoring section of the console.

· Improved the product knowledge for the alert generated by the A Service is Misconfigured rule.

· Fixed issue in which logical disk health check could have performance problems when run against clustered servers.

· Fixed links to views in product knowledge articles.

· Added Active Alerts views for Windows Server 2003 and Windows Server 2008.

· Added retry logic to the "Probe Module: Is Feature Installed" module to avoid failures due to periodic time-outs.

· Added a new integer property named "Size (MBytes) (Numeric)" to the Logical Disk class and updated the existing property "Size (Bytes) (String)" to clarify that it is a string. The new property can now be used in formulas and views as expected.

 

Thanks,

ALexandre Verkinderen
