SCDPM 2010: Backup Machines in a Workgroup/DMZ. How to protect your Hyper-V Servers that are not domain joined

April 13, 2010 Leave a comment
 

One of the greatest features of SCDPM 2010 is the ability to backup machines that are in a workgroup/DMZ/untrusted domain. This is good for example because some of my Hyper-V serveres are in the workgroup mode.

1.  Install the DPM agent on the server you want to protect. Copy the agent folder to that server and double click the EXE and wait for the message to tell you that the agent was installed successfully.  You then might need to reboot.  

    • x86 : <installation drive>Program FilesMicrosoft DPMDPMProtectionAgentsRA3.0.7558.0i386DPMAgentInstaller_x86.exe
    • x64 : <installation drive>Program FilesMicrosoft DPMDPMProtectionAgentsRA3.0.7558.0amd64DPMAgentInstaller_x64.exe

Also, copy the SetDPMServer.exe from <installation drive>Program FilesMicrosoft Data Protection ManagerDPMbin

Once the agent is installed it needs to be configured.  This is done using SetDPMServer.exe 

2. Run SetDPMServer.exe with following arguments, you need to specify the DPM server name and a user name for a new local account to be created.

SetDPMServer.exe -DPMServerName <DPMServerName> -IsNonDomainServer -UserName <NewUserName>

You will be prompted to give a password for the new user account and to confirm it, once done the agent is configured and the relevant changes have been made to the Windows firewall.

 

3. Now the agent needs to be attached to the DPM server.  Attaching DPM agents to a DPM server can be done through the DPM GUI .  

  • To attach a non-domain server agent:
  • Open the DPM console 
  • Select the Management Pane
  • on the Actions menu, Click Install   
  • Select Attach agents,  when the Protection Agent Installation Wizard opens.
  • Type the name of the untrusted computer that the DPM agent is installed on
  • Type the user name and password specified when running SetDPMServer.exe.  
  • Click "Add >" to add the computer to the selected computers list.
  • Click Attach

 

Now, you can create a protection group to protect the data on the machine. To do that, click on Protection Pane and select Create Proection Group, as usual

SCOM 2007 R2 : The System Center Management service terminated with service-specific error 2147500037 (0x80004005).

April 9, 2010 Leave a comment
 
When upgrading from System Center 2007 R1 to SCOM R2, after removing the old agent and installing the new one inone of the servers, I got this error : The System Center Management service terminated with service-specific error 2147500037 (0x80004005).
I checked the status of the System Center Management Service and was stopped. I tried to start it fail.
 
 
Here how I fixed it :
 
1. Enable ETL Verbose Logging from the Program FilesSystem Center Operations Manager 2007Tools  directory. At the command prompt, run: 
StartTracing.cmd Verbose
2. Attempt to start the System Center Management Service. Let it fail.
3. Turn off ETL Verbose Logging from the Program FilesSystem Center Operations Manager 2007Tools directory.At the command prompt, run: 
StopTracing.cmd
4. Evaluate the ETL Logs for HealthServiceCommon
5. Open the register Key and look for HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesHealthServiceParametersState Directory
6. Verify the value that it contains. It should point to the location in which the agent is installed and the Health Service State subdirectory (Program FilesSystem Center Operations Manager 2007Health Service State), change the value to correct location if
incorrect or create a new String Value (Reg_SZ) if missing and set it to the correct path
7. Check for HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesHealthServiceParametersManagement Group<YOUR Management Group Name Here> being invalid or non-present. The easiest way to resolve the issue with the Windows AccountLockDownSD key is to export this specific registry key from another working server and then import it in to the registry of the server experiencing the problem. 
Once this is complete the System Center Management Service should start successfully

VMware to create patch to fix performance behind Hyper-V R2 and XenServer

March 26, 2010 Leave a comment

 

In a recent update of the phase II of Project VRC, VMware was behind Hyper-V R2 and XenServer.

Although XenServer and  Hyper-V R2 performed nearly identical, Vmware get behind by 10%-30%. VMware responded to the findings  and wrote a fix for VMware vSphere 4.0 to try to close the gap :

 "…What we discovered led us to create a vSphere patch that would allow users to improve performance in some benchmarking environments."

There are three specific conditions that can excite this condition:

  1. A Xeon 5500 series processor is present with Hyper-Threading enabled,
  2. CPU utilization is near saturation, and
  3. A roughly one-to-one mapping between vCPUs and logical processors.

In this scenario, VMware vSphere favors fairness over throughput and sometimes pauses one vCPU to dedicate a whole core to another vCPU, eliminating gains provided by Hyper-Threading

VIRTUALIZING Terminal Server : analyzing Terminal Services (TS) workloads running on the latest generation hardware and hypervisors

March 25, 2010 Leave a comment
 

Virtualizing Terminal Server and Citrix XenApp workloads is highly recommended, for managment and consolidation benefits and if you are thinking on x86 TS so far for more scalability.

So, If you are planning to run Terminal Server in a Virtual Environment, you shoud read the The Project VRC phase 2 whitepaper, that focuses completely on analyzing Terminal Services (TS) workloads running on the latest generation hardware and hypervisors.

Here is a brief summary :

"When comparing hypervisors, performance is close to equal throughout when no Hyper-threading is used by the VM’s. In all test the hypervisors perform with a 5% range with the Terminal Server workloads, with a slight edge for vSphere 4.0. Utilizing Hyper-Threading, on all platforms a performance increase in seen, but vSphere 4.0 trailing slightly by 15% in comparison to XenServer 5.5 and Hyper-V 2.0. These differences are only visible under full load.

Strikingly, XenServer 5.5 and Hyper-V 2.0 perform almost identical in all tests. The only differentiator between these two is that XenServer 5.5 (and vSphere 4.0) support 8vCPU’s, where Hyper-V 2.0 has a maximum of 4vCPU per VM" 

if you are curious about the impact of different hypervisors and the performance differences with various hardware and if you are searching for best practices for your virtual Desktops … Project VRC whitepapers are a must read!

Dynamic Memory Coming to Hyper-V

March 25, 2010 Leave a comment
 
Most of the time, we overprovision our hardware not using it efficiently which in turn raises the TCO. Sometimes because we use vendor recommedations, minimum system requirements, or either if our users complain. So far, this is not the solution
Wouldn’t it be great if your workloads automatically and dynamically allocated memory based on workload requirements and you were provided a flexible policy mechanism to control how these resources are balanced across the system?

Microsoft System Center Virtual Machine Manager Agent — WS-Management service is either not installed or disabled.

March 22, 2010 Leave a comment
 
If you are trying to ADD a MS Virtual Server 2005 R2 SP1 Host, running under Windows 2003 SP2,  to the System Center Virtual Machine manager and are getting this error:


"Product: Microsoft System Center Virtual Machine Manager Agent — WS-Management service is either not installed or disabled. Verify that Windows Hardware Management is installed and the Windows Remote Management service is enabled. Refer to the FAQ for more information."

You should install the KB 936059.  This update adds a new feature to Windows Remote Management (WinRM). This update also updates the version of Windows Remote Management that is included with Windows Server 2003 R2

 

 

Post-installation instructions

On a Windows Server 2003 R2-based computer that has the Windows Hardware Management optional component installed, the WsmanSelRg collector-initiated subscription collects events form the BMC. This subscription has a URI property that is set to wsman:microsoft/logrecord/sel. After you apply this hotfix, the WsmanSelRg subscription will not work until you set the URI property to the following:

To set the URI property, run the following command at a command prompt:

IMPORTANT NOTE:
 
if you are not running the Virtual Server 2005 R2 SP1 version, the you will get the error 10418. Virtual Machine Manager cannot add host xxx.xxx.xxx.xxx because this version of Virtual Server installed on the host is not supported.

Windows 2008 R2 : No Restrictions for Network adapter teaming in cluster environment

March 16, 2010 Leave a comment
 
Network Teaming, allowing us to group network adapter ports for a connection to a single physical , are available from some hardware manufacturers to provide fault tolerance. It means that if connectivity through one port is not working, another port is activated automatically. This operation is transparent to the operating system and other devices on the network.

In Windows Server 2008 and Windows Server 2008 R2, there are no restrictions that are associated with NIC Teaming and the Failover Clustering feature and allows it to be used on any network interface in a Failover Cluster.

 

The following table details the recommended, supported, and not recommended network configurations for live migration, and is organized in the order in which each network configuration is commonly used. Before reviewing the table, note the following:

  • When a network adapter is connected to a virtual switch, it is referred to as a virtual network adapter.

  • Network access for virtual machines can be on either a public or private network. To allow virtual machines access to computers on the physical network, they must be on a public network. The requirements for virtual machine access vary depending on network I/O needs and the number of virtual machines you are running on a single physical server.

  • In addition to the preferred network for the cluster and the Cluster Shared Volumes, a cluster can utilize at least one additional network for communication. This increases the high availability of the cluster. The cluster should also be on a private network.

  • If a network configuration is listed as “not recommended” in the following table, it should not be used because the performance of live migrations declines and cluster nodes might crash. Add another network adapter to separate traffic between live migration and Cluster Shared Volumes.

Hyper-V : The system time runs too fast on a Linux-based vm

March 8, 2010 Leave a comment
 
If you create a Linux VM on 2.6 Kernel and if you are experiencing the system time in the Linux guest operating system running too fast, this is the step to fix:
 
1. Open the Linux console
2.  Edit boot menu
   vi /boot/grub/menu.lst 
 
3. In the title Linux area of this file, add the clock=pit parameter to the kernel entry
 
 
4. Edit the NTP.CONF file
   vi /etc/ntp.conf
   
5. Add the NTP server ( click here to know more about NTP Server in windows 2008 )

 
6. Edit the CRONTAB:
 crontab -e
 
7. Type : 30  *  *  *  * /usr/sbin/ntpdate -su
 
Done. Now, every 30 minutes, the Linux VM will sync with the NTP server.
