VMware vRealize Operations 2017 Specialist Exam (2VB-602)

“Specialist Exams”….Wait, what?

I have a requirement to essentially get more up to speed with vRealize Operations Manager. As I was digging through some of the reading material I came across the specialist exam. The details for which can be found here.

I wasn’t actually aware up until this point VMware actually offer specialist exams. At time of writing vRealize Operations and vSAN are the only two specialist certifications you can take.

I can understand the logic behind it – vRealize is becoming a very comprehensive suite of applications and with the VCP7-CMA certification primarily focused on vRealize Automation, it makes sense to separate out certain technologies into their own curriculum.

2VB-602 (vRealize Operations)

For a couple of weeks or so I’ve been messing around with / reading up on / watching videos of vRealize Operations primarily focused on 6.6 without even knowing about the certification. The exam, however, is based on 6.0 – 6.5 and 6.6 brings some rather substantial changes. Therefore don’t expect to see 6.6 related questions in the exam.

Resources

Although I wasn’t actually focused on passing this specific test, Here’s what I’ve used so far in an attempt to get up to speed:

 

Pluralsight’s training course on vRealize Operations (created March 2017) – https://www.pluralsight.com/courses/vmware-vrealize-operations-manager

VMware’s documentation center – https://docs.vmware.com/en/vRealize-Operations-Manager/index.html

vApp Deployment and Configuration Guide – https://docs.vmware.com/en/vRealize-Operations-Manager/6.6/vrealize-operations-manager-66-vapp-deploy-guide.pdf

VMware training videos – http://players.brightcove.net/1534342432001/S1xUFpuYwx_default/index.html?playlistId=5446534362001

Exam Experience

The exam can be taken anywhere unlike the VCP or VCAP exams which require you to attend a training center. The questions were pretty tough, but that may have come down to my lack of experience with the product.

Overall, it was a interesting experience. I probably would have preferred vRealize Operations to have it’s own VCP level exam being proctored etc. It’s a nice-to-have, but I still have a lot to learn about vRealize Operations but it’s given me some confidence that I’ve probably understood the fundamentals.

 

NSX Livefire Course

 

Recently I was lucky enough to attend a NSX livefire course hosted at the VMware EMEA HQ in Staines, It’s designed to facilitate a intensive knowledge transfer of NSX related subject matter. All participants are bound by NDA, however most of the information is GA with the exception of roadmap information.

 

Day One

Day one was focused on introducing all the participants, laying a foundation for the course objectives as well as some background info on NSX. In addition the following topics were covered:

  • Lab intro
  • Dynamic routing and operations
  • Integrating NSX with phyiscal infrastructure

Day Two

We covered:

  • Security
  • Multi site implementations
  • Business continuity and disaster recovery

Day Three

We covered:

  • Operations and Troubleshooting
  • Cloud management integration

Day Four

We covered:

  • VDI
  • Best practice

Overall, it was a very packed few days but an extremely valuable and positive experience. I would strongly recommend  attending if given the chance.

 

Homelab – Nested ESXi with NSX and vSAN

The Rebuild

I decided to trash and rebuild my nested homelab to include both NSX and vSAN. When I attempted to prepare the hosts for NSX I received the following message:

 

 

I’ve not had this issue before so I conducted some research. I found a lot of blog posts / comments / KB articles linking this issue to VUM. For example : https://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2053782

However, after following the instructions I couldn’t set the “bypassVumEnabled” setting. Nor could I manually install the NSX vibs and was presented with the following:

 

[root@ESXi4:~] esxcli software vib install -v /vmfs/volumes/vsanDatastore/VIB/vib20/esx-nsxv/VMware_bootbank_esx-nsxv_6.5.0-0.0.6244264.vib –force

It is not safe to continue. Please reboot the host immediately to discard the unfinished update.
Please refer to the log file for more details.
[root@ESXi4:~]

In particular I was intrigued by the “Failed to release memory reservation for vsfwd” message. I decided to increase the memory configuration of my ESXi VM’s from 6GB to 8GB and I was then able to prepare the hosts from the UI.

TLDR; If you’re running  ESXi 6.5, NSX 6.3.3 and vSAN 6.6.1 and experiencing issues preparing hosts for NSX, increase the ESXi memory configuration to at least 8GB.
