Top 10 DevOps Myths

As I’m exploring Open Source more and more, DevOps is a common, and key element in play. Jason Hand (@jasonhand) has a great write up on the myths of #DevOps, check it out here:

Top 10 DevOps Myths Debunked


Windows Server 2012 R2 VMs and the Network Location wizard

With Win2012 R2 VMs deployed with vCloud Director there was the annoyance of having the Network Location Wizard popup on 1st Login, asking to discover new networks. Answer ‘Yes’ and things were fine, answer ‘No’, and *BAM* not RDP.

A quick search points to a TechNet article for turning this off for Windows 2008 R2 and Windows Server 7 for all users or current user. As there maybe multiple users logging in I wanted the ‘all users’ option, which called for the following steps:

  1. Click Start, and then click Run.
  2. In the Open box, type regedit, and then click OK.

    Registry Editor opens.

  3. In Registry Editor, click Edit, click New, and then click Key.
  4. Type the following registry entry:


1st things first, there’s no Start in Windows 2012 R2. OK, you can just open a cmd window and type in regedit, that’s not a problem. Once in regedit I tried steps 3 & 4 and was greeted by:

I next tried just drilling down to the location specified and was of course able to create a key there as there were no “\” in the name.

#Success, right?

I thought so, and went about a reboot, clean shutdown, adding it back to the Catalog, and then deploying back to ‘My Cloud’. Guess what I saw on my 1st Login?


Now what? I went back to my search and checked a few other sites and most of them pointed me back to the same TechNet page or something similar. There were a few pointers to Forums that wanted me to download a Reg Key, umm, that would be ‘No’. I did find something that looked promising here, that looked interesting.

Just using a simple ‘reg add HKLM\System\CurrentControlSet\Control\Network\NewNetworkWindowOff’

It was the same desired result the TechNet article alluded to, but Windows being Windows, I thought giving this method a try was worth the time, the little it would take to open cmd and paste that puppy straight in.

Turns out that it did the trick, after the reboot, shutdown, add to catalog, and add to ‘My Cloud’ shuffle I’ve not seen the Network Location wizard again…back to OZ/Redmond with you sir!

My Pre-EMC World 2015 Workout Challenge

After a tough New England Winter it’s time for some personal change!

As a a preparation for this years EMC World I’m starting a personal challenge, and anybody’s welcome to join me!
Here’s my plan for the next 30 days prior to departing for EMC World in Las Vegas on April 30th:
2x 7-Minute Workouts everyday (Courtesy of ‘The 7 Minute Workout’ App on my iPhone)
1x 10-minute Yoga everyday (A YouTube Search yields lots of results for this)
10,000 Steps everyday (Courtesy of my iPhone and UP24 App)
64 oz of Water consumed everyday (Guidelines from WebMD are 125 oz for men, so I’m going for 64 oz of just water and my coffee intake should take care of the rest)

I’ll be working on eating better too to fuel my endeavor.( I’m tracking calories via ‘My Fitness Pal’ App on my iPhone)

Brushing away the Cobwebs

Life’s been busy since my last post and this place is all dusty and full of cobwebs…time for a little spring cleaning and a return to writing. 

Some of the changes since my last post include a new role for me, EMC vLab Technical Program Manager. That’s a mouthful to say and the job itself is just as big. To condense it down to its simplest meaning you could say that I now herd cats. 


More on that to come… 

VNXe 3150 OE Upgrade Process

The VNXe 3150 is a tidy little array that packs quite a punch, and I’m happy that I have access to one.


It handles my CIFS and NFS storage as well as running a small vSphere VM load. I’m running my VMs over NFS as that’s what I work with in vLab and want a similar setup as a playground.

I handle all the management over it and try to keep up with the OE Upgrades. I saw an internal post recently looking for info on the OE upgrade steps and remembered I had taken some screen shots during my last upgrade. So for your reading pleasure let’s take a stroll through the process.

  1. Locating the latest release, or older releases for that matter couldn’t be easier. Pull up your favorite inter webs browser and point it at Login with your credentials, you do have an account right? Select your product, and then click the Download section. You’ll see a list of all the great stuff available for that product, VNXe in our case, and select it to start the download to an appropriate location. I’ve just saved mine to the Download directory on the Server I use for management: Image
  2. Next I’ll point my browser to the Unisphere address of my VNXe and login. Navigate into ‘Settings->More configuration…->Update Software’. This is also where you can connect to download updates using ‘Obtain Candidate Version Online’ option in the lower left. I like browsing through the Support Download area just to see if there is something I missed…LOOK! Squirrel! :Image
  3. You’ll want to run a Health Check to make sure things are in good order, and Unisphere will let you know if not. Click on ‘Perform Health Check’ and then ‘Run’:Image
  4. If you come up a winner now you can upload the update, if not…fix that thing!
    Head back over to Support or ECN Forums and get some help if needed. Once you’re in the winners circle, click on ‘Upload Candidate Version’: Image
  5. It shouldn’t take too long and you’ll have the latest and greatest ready to go: Image
  6. Once uploaded the system checks the file integrity: Image
  7. Then lets you know things are in place: Image
  8. Clicking ‘Install Candidate Version’, and I know you want to, will bring up this handy little reminder, and you should follow the advice given: Image
  9. Now I would normally due this over a weekend, after backups completed, or during some other low usage window, but since I was taking some screen shots I ran this during the day with most of my VM’s suspended.
    **Read the Guides. Make sure you have good backups. Low or no I/O on the array and the Health Check was run without errors reported. And you have enough free space to run the upgrade. Read the Guides**
    Now we are ready to click ‘Install’ and watch the progress: Image
  10. In the Dual SP arrays the Peer SP gets the update applied first, and rebooted. Anything running on the Peer SP gets failed over to the Master SP, this is one reason you don’t want a load running when upgrading as you’ll see degraded performance: Image
  11. Once the Peer SP comes back up, the upgrade gets finalized, and the Master SP load moves to the Peer SP so the Master gets a turn for the upgrade reboot:Image
  12. Once the Master SP is back online and the load is shifted back to your original config the upgrade is complete! Woo Hoo! You’ll have to logout and back in to load the changes in Unisphere: Image
  13. Once logged back in you’ll see any changes in Unisphere, if there are new features that you are licensed for they will be available for use and nows a good time to check them out before you get busy… Image

I hope that was helpful, and maybe took away some of the intimidation of performing the upgrade. I can’t stress enough to read the guides, and check out the ECN Forums to post any questions or read what others have already posted…LOOK! Squirrel!
