First VMbook published

Filed under: Disaster Recovery,VMbook — A. Mikkelsen @ 9:59 am

“This first VMware® VMbook focuses on Business Continuity and Disaster Recovery (BCDR) and is intended to guide the reader through the step-by-step process to set-up a multisite VMware Infrastructure that is capable of supporting BCDR services.

The VMbook will provide very valuable insight into the considerations and design principles for a multisite virtual infrastructure data center that leverages array based replication for the replication of VMFS datastores; which is one of the prerequisites for Site Recovery Manager 1.0. The VMbook authors suggest your customers leverage this VMbook as a reference even if they are planning to implement a Site Recovery Manager based BCDR solution day one, as the BCDR solution detailed in this VMbook provides design principle guidance for a successful multisite virtual infrastructure data center deployment which is the underpinnings for a successful SRM deployment.”

The VMbook is available for download from: http://www.vmware.com/resources/techresources/1063

Automate the installation of multi ESX hosts

Filed under: Scripting,Tools,vSphere (ESX) — A. Mikkelsen @ 21:20 pm

A Danish VSP instructor (Tommy) told me about a cool looking tool to deploy ESX hosts with a consistent standard.

V-Ployment comes in two versions.

  • A free version for deploying up to two servers.
    The free version is limited in features but gives you the basic.
  • The full version offers a lot more features.

This tool is easy to use and configure.

Problems with WSUS. Fails or Not Working

Filed under: Microsoft,Tools — A. Mikkelsen @ 17:59 pm

Today my WSUS stopped working, every time i tried to install a new update it failed.
I googled a bit and found a few guides to get it working.

I have had the best luck with Method 2.

Here is what you need to do:
Method 1:

  1. Open a command prompt. (If you don’t know how please contact a technical support person)
  2. net stop wuauserv
  3. regsvr32 /u wuaueng.dll
  4. del C:\WINDOWS\SOFTWAREDISTRIBUTION
  5. del C:\WINDOWSUPDATE.log (if this tells you that it is in use just go to the next step).
  6. regsvr32 wuaueng.dll
  7. net start wuauserv
  8. wuauclt.exe /resetauthorization /detectnow

Method 2:

  1. Open a command prompt. (If you don’t know how please contact a technical support person)
  2. net stop wuauserv
  3. regsvr32 %windir%\system32\wups2.dll
  4. net start wuauserv

Method 3:

  1. Download the relevant version of Windows Update for your system
    AgentWindows, x86-baserede systemer

  2. From Start -> Run click Browse and browse to wher you downloaded the Windows Update installation.
  3. Add the following /wuforce to the end of the path.
    C:\WindowsUpdateAgent30-x86.exe”/wuforce
  4. Click OK
  5. Follow the installation guide

There you go, you should be able to request Windows Updates and they will download and install as you expect.
