Azure Stack: Patch and Update a Dell EMC VxRack.

The last blog I did on updating Azure Stack was focused around the Microsoft PNU processes.  This blog I will walk through how to update the Dell EMC Hardware LifeCycle Host (HLH) Server along with the OME and OMNM VM that runs on the HLH server.

From what I understand, firmware and drivers will be included in this process as well for all hardware included in a Del EMC scale unit.  However, between 1803 and 1804 there have only been Windows cumulative Updates.

 

Download the content

The first thing that you need to do is download the content needed to update the Dell EMC servers.   This can be done by going to the following Dell EMC Link:

Cloud for Microsoft Azure Stack 14G

You will need to download two items.  The first being the most recent update guide called “Dell EMC Cloud for Microsoft Azure Stack Powered by Dell EMC VxRack AS Patch and Update (Version Number).  The other would be the Dell EMC Tools which is also called Cloud for Microsoft Azure Stack 14G Customer Toolkit 1-0-version-x.zip.  For this blog, I am using the 1804 version that was released last month.  Dell doesn’t have an 1805 version released at this time.

I have logged into my OME-VM VM using the proper credentials provided by Dell EMC.  I have also created a directory structure to keep my updates organized.  For this update, I have created C:\Dell EMC Updates\1804\ and have downloaded and extracted the Dell EMC Tools and have also downloaded the update guide as well.

Next, you will need to extract the firmware executables.  Within that Dell EMC Updates\1804 directory there should be a file named DellEMC-VxRackASPowerEdgeR740xd-<version>.  Double click on that file and extract it into the same directory, for example, C:\Dell EMC Updates\1804

Now we are ready to update the HLH and the 2 VM’s that run on the HLH.

Updating the HLH (Hardware Lifecycle Host)

Log on to the HLH server and run the following steps to update Windows Server 2016.

  1. RDP to your HLH server.
  2. Copy the Cumulative update located in the HLH_Cumulative_Windows_Update folder which is located in the Dell EMC Tools directory on the OME VM.Note: I could not connect to the OME VM from the HLH server via a UNC path.  I had to create a share on the HLH server that I then gave everyone permission to everything on that share before I could copy this file over.  I will need to check with Dell EMC about this procedure.  The documentation I follow doesn’t mention how to move the file but only just to move it.
  3. On the HLH server, double-click the Windows Update package that was just copied over.
  4. Click on Yes when prompted to run the installer.Note:  At the time of this blog I was getting errors that the service was disabled.  I checked on the HLH and the Windows Update service was disabled.  I changed it to Manual and started the service.  Then continued with the installation of the critical update.
  5. The update may take some time to complete.  When it is completed, reboot the HLH.

 

Updating OME and OMNM VM’s

This is a repeat of how you would have updated the HLH server.

  1. RDP to the OMNM VM
  2. Copy the Cumulative update located in the HLH_Cumulative_Windows_Update folder which is located on the HLH Temp Share created earlier.
  3. On the OMNM VM, double-click the Windows Update package that was just copied over.
  4. Click Yes when prompted to run the installer.Note:  At the time of this blog I was getting errors that the service was disabled just like the HLH server.  I checked on the OMNM server and the Windows Update service was disabled.  I changed it to Manual and started the service.  Then continued with the installation of the critical update.
  5. The update takes some time to complete.  When it is completed, reboot the OMNM VM.

Now repeat the above steps for the OME-VM.  However, one thing that you do not need to do is enabled the Windows Update Service.  On this VM that is already enabled.  At least it was on my VM.  Reboot the machine when done.

 

Final Thoughts

My assumption is that this will all be automated at one point.  Also, the firmware and drivers will be included when released as well.  However, I have only had a multi-node Azure Stack for a short time period now.

Also at this point, once you have updated the HLH and the two VM’s you should start your Azure Stack update for the same release as well.
