DISM GUI moved to GitHub

February 19, 2018 2 comments

With the shutdown of Codeplex I have moved the source code and download for DISM GUI to GitHub.  No changes have been made to the source code and only the last release of DISM GUI is available.

I have not had time to update DISM GUI in the past few years due to other responsibilities.  Maybe I will be able to get back to it someday but right now I don’t see that happening soon.

Finding which LUN a datastore is on

January 25, 2018 Leave a comment

Recently we were doing some reconfiguration of our SAN and need to consolidate our VMFS datastores.  This required us to remove some LUNs and datastores.  While I was pretty confident our naming convention was correct between VMWare and one of our SAN arrays I wanted to be extra careful when removing the LUNs.  To my surprise I could not find a way to see which LUN a datastore was on in VMWare vCenter (6.0).  I checked everywhere I could think of but could not find any mapping.

Even though this information is not exposed in vCenter you can easily find it with PowerCLI with a simple one liner.

get-datastore “Datastore Name” | Get-SCSILun | ft CanonicalName

This finds the VMFS datastore and pipes the object over to Get-SCSILun which returns the LUN it’s store on.  You can do this for all datastores but the Get-SCSILun cmdlet is very slow so if you have dozens or hundreds of datastores this can take a while to run.

DISM GUI 4.0 Beta Available

September 25, 2014 48 comments

It’s been a long time coming but I finally got around to updating my DISM GUI program to version 4.0.  I am treating this release as a beta as I have not had a chance to fully test everything yet.  You can find the download on the DISM GUI GitHub site.

A few of the changes I implemented in this version

  • The .NET framework 4.0 is now required.  The previous version required 2.0.
  • Updated for DISM 6.3.  This version may work with older releases of DISM but some feature may not be available.
  • Added Capture and Apply tabs – This was the single most requested feature.  Requires DISM 6.2 or higher
  • Added a Read Only option to the mount control tab
  • Corrected some spelling errors

This version *should* run under WinPE however I have not tested it yet.  If anyone has success running it under WinPE make sure to leave a comment.

Upgrading iLO 2 Firmware through SSH

May 12, 2014 4 comments

Recently I had a problem upgrading the iLO firmware on one of our servers through the GUI.  This particular server did not have an OS on it at the time so normally I would update through the web interface.  However since the firmware on this machine would not work with IE 11 I had no choice but to upgrade through SSH.

Before you start copy your firmware file (ilo2_225.bin in my case) to a local web server and make note of the URL.

  • Login to the iLO with your favorite SSH client.
  • Once connected type “cd map1/firmware1”
  • Now type the following command replacing the URL with your own URL.

         “load –source

  • The update will now begin.  It can take up to 10 minutes for the process to complete.  You will be disconnected from your session during the upgrade. 
  • Login to iLO again and type “version” to verify the update has been completed.

HP iLO Reset

May 9, 2014 2 comments

Resetting an HP iLO2 using SSH or Telnet isn’t the most obvious thing to do. Recently I had one where the web interface wasn’t responding and I didn’t want to power down the server to reset iLO.

  1. Connect to the iLO IP address using your favorite SSH client. I prefer Putty.
  2. Login with your Administrator account. Don’t forget bother username and password are case sensitive.
  3. Once logged in you need to go to the map1 directory. type cd map1
  4. The type reset. The iLO card will restart immediately after that.

Easy as pie!

Preinstalling IE10 on Windows 2008 R2/Windows 7 could cause issues in MDT 2012

August 2, 2013 Leave a comment

I was updating our current Windows 2008 R2 image for MDT with all the latest security updates and ran into an annoying issue. After capturing the image and deploying it to VM (or a physical machine) I kept getting the error “Windows could not parse or process the unattend answer file for pass [specialize]”. I thought this was really odd because MDT created the Unattend.XML file for me. The same process has worked for me for over a year, why all of a sudden did it stop working?

I found my answer at this link. I must of accidently installed IE10 when doing my security updates. In the unattend.xml file there is a line for IE9 called . This does not existing in IE10 so it causes the specialize phase of Sysprep to fail. Below is a excerpt from the unattend.xml file that was causing the issue. You just need to comment out the line  <IEWelcomeMsg>  and you should be all set.

SQL 2008 R2 Edition Upgrade Architecture Mismatch

August 2, 2013 5 comments

Recently I had to upgrade a SQL 2008 R2 Express edition to Standard.  I knew with SQL 2008 R2 this was very easy to do using the wizard.  However on the server I was trying to change the edition on I kept getting an error during the checks about architecture mismatch.  I thought this was weird since the installer includes both x86 and x64 versions and choose the correct version based on the OS.

Well it turns out the application that installed SQL Express installed the x86 version even though the OS is x64.  When starting the SQL installer it automatically chose the x64 version to match the OS.  No matter what I did it would not find my x86 version of SQL Express already installed.  I found lots of other people on the Internet with the same issue but it looks like most people just gave up and installed SQL over again.

I knew there had to be a way and after messing with the SQL installer I found it.  Buried in the Options of the SQL installer is a way to choose your processor type. 


Changed it to x86, started the installer over again and bam instantly recognized the Express version installed.  5 minutes later I was happy camper.  Hopefully this help out someone else that was having the same issue!
