I’ll be updating this post with things I learn about 3.6 as time progresses.
Change IP / Gateway / Hostname / DNS / Proxy Server
- This *could* be done within your standard Linux commands, however, Tomcat is running in the background and does require manipulations also.
- The recommended process is using a bash shell script named “vami_config_net” – this is under /opt/vmware/share/vami/
- Run the script from your console to get the menu:
- Pretty self-explanatory on what it requires after you select a sub-menu.
SSH and Root Logins
- SSHD is not started by default nor can you log in with the root credentials. IF it is required (by VMware Support), this is the process on enabling access.
- To enable root, edit /etc/ssh/sshd_config and look for line “PermitRootLogin” – change this from no to yes
- Then start (or restart) the sshd service – “service sshd restart/start”
- NOTE – This should be a TEMPORARY solution if you need to access the shell via root. Follow all security practices when possible!
Root account locked
- Yeah, don’t ask how I did this – but had to figure out the procedure on unlocking the root account.
- Simple instructions here on getting into the bash shell from GRUB – https://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2147190
- From there, you’ll need to use the “pam_tally2” command to reset the lock on the root account.
- So… “pam_tally2 –user=root –reset”
- Ensure your path is set if it errors out: “export PATH=”/sbin:/usr/sbin:/usr/local/sbin:/usr/local/bin:/usr/bin:/bin”
With our new release of vCloud Usage Meter 3.6, I have several SP’s requesting the work effort for migrating from 3.5 to 3.6 Usage Meter. I am doing this in my lab environment and showing the steps required for the data migration.
Official Instructions: https://docs.vmware.com/en/vCloud-Usage-Meter/3.6/com.vmware.vcum.usersguide.doc/GUID-88DD4D6B-B357-46D5-A6B7-AC1EDB7F423E.html
- Usage Meter 3.6 appliance stood up and IP’d – you do not need to point it to your Products (migration tool will take care of that)
- Snapshot BOTH UM appliances
- SSH turned on both 3.5 and 3.6 appliances. NOTE: 3.6 requires you to change the /etc/ssh/sshd_config to allow root logins. Change “PermitRootLogin” to yes and restart sshd
- Timezone is the SAME on both appliances
- Under Manage -> Provider, ensure the Contract, Phone, Partner ID, Contract Number, and Site ID MATCH
- SSH to both appliances as “usgmtr” – NOT root
- Run “migrateum <hostname-of-UM3.5>
- And if you forgot to SSH as the usgmtr account, you’ll get this!! 🙂
- OK, SSH now as usgmtr on the 3.6 appliance – running “migrateum usage35.corp.local”
- IF you met the pre-reqs above, you should get a confirmation screen like this:
- After confirming, you should see the copy operation start. I didn’t have much data on my UM instance, so this was pretty quick.
- Let’s log into the 3.6 instance….
- You’ll get the confirmation page again to accept the terms:
- Accept the certificate for any product (I had vROps pop up):
- vCD was not showing up for me also – I had to check the box “Show inactive” and Activate:
- What’s great is all of my Customers and Rules moved over…
- And previous Report data is there!
Once you verify everything looks good, DON’T FORGET TO REMOVE YOUR SNAPSHOTS!!!
Not a very tough migration – just ensure your 3.6 UM is configured exactly the same way as the 3.5 instance or the migration tool will error out.
Hot off the presses here – VMware has released a new content page for go-to information for install, configuration, and management guidance.
Things to point out:
- vCenter High Availability Overview – https://vspherecentral.vmware.com/#!/vcenter-server/configuration-and-day-2-operations/vcenter-high-availability-overview
- vROps Performance and Health Monitoring Guidance – https://vspherecentral.vmware.com/#!/operations-management/performance-and-health-monitoring
- Command-Line Interfaces – https://vspherecentral.vmware.com/#!/developer-and-automation-interfaces/command-line-interfaces
This is a GREAT go-to page for core functions from a lifecycle perspective. Get this out to your teams!
This is a nice little jewel available in the VMware Solution Exchange – ability to monitor vCD objects and provide potential tenant integration for monitoring their org.
More info here: https://marketplace.vmware.com/vsx/solutions/management-pack-for-vcloud-director
To install it – it’s pretty easy:
- Download the PAK file
- Toggle to Administration -> Solutions in vROps
- Hit the + Button on Solution
- Select your PAK file and click Upload
- Accept the EULA
- Let vROps do it’s thing – installing…
- Click Finish once it’s complete.
- Now find the Management Pack for vCloud Director under Solutions. Go ahead and click on the gear icon to configure your connection.
- Add your instance along with the Display Name, org you want to connect to, and credentials. Pretty similar to other connections. Note – ensure Auto Discovery is set to “True” if you want new objects to propagate to vROps!
- Test your connection – if successful, you should start seeing Data Receiving under the Collection Status
- Toggle over to Dashboards -> you will see several new vCD dashboard available from All Metrics, vApp Utilization, Alerts, etc.
- From here, one could provide tenant access to a specific dashboard and/or org from vROps that provides a vCD view.
Yet another great addition for vROps 6.6 – definitely check it out if you are a vCD user!
Installation Guide is here.
I just upgraded my current vROps 6.4 instance to 6.6 – didn’t really know what it would take to do this.
Well, I can say this was one of the easiest updates I’ve ever done. I can summarize this in five steps.
- Download the appropriate PAK update file from vmware.com – there’s a few versions you can download. I’m running the vApp, so downloaded that.
- Log into the admin console – so https://<vrops-ui>/admin
- Click on Software Update -> Install a Software Update
- Upload the PAK file – agree to the terms
- Sit back and let it do its thing.
There’s 9 steps during the upgrade process. The admin page will time out during the appliance reboot. Once it comes up, the new GUI is evident.
Once it hits 9 of 9 – click on System Status on the left. You’ll see your applicable nodes and the current state.
I love the new interface, but also the immediate usability of 6.6. On the left side, I can see immediate recommended actions and workload balance.
Just incredible for a “minor” release.
So new SBR build has been completed and tested at the range.
Here’s my build specs:
- PSA Stripped Lower (engraved for SBR Form 1)
- Aero Precision Upper
- Aero Precision 10.5″ Barrel
- Magpul SLK stock and grip
- Trijicon MRO with LaRue QD Mount
- Geissele MK8 Rail 9″
- AAC 51T Mount
- Using a AAC 7.62SDN can currently
- Streamlight Rail-Mount HLX
So function was great, even suppressed. Things I noticed however:
- Wow, the rail gets HOT after 20 to 30 rounds. Hot enough I could not hold it. After researching it, it seems these slim-lined rails are known for that. Plus, I wasn’t using gloves on a 95+ degree day.
- I’ll probably install the larger plastic MLOK guards to help with this heat issue.
- This was to be expected, but was getting some gas blowback after heavy sustained fire. I’ll need to install an adjustable gas block to contain this. Moreover, I noticed ejection at 2 o’clock when running suppressed. I want this down slightly to 3 o’clock.
Love SBR’s and after some slight tweaks, this will be my go-to rifle!
I took the new 2v0-642 NSX certification on Tuesday and lo and behold, I passed!
I am going to very careful so I do not violate any NDA, but I wanted to provide an updated perspective on the 2v0-642 test. As many of you know, 2v0-641 test has been around for several years and has been recently retired.
Moreover, many of the study guides available are on 641 – my understanding is 642 was quite different.
642 focuses on NSX 6.2x feature-set – one of the biggest changes is the addition of cross-vCenter vMotion.
So what did I do to prepare for this?
- I took the VMware NSX for Internetworking Experts Fast Track [V6.1] Class. Yes, that’s right – I took the older class. Why? Well, I wanted to take a remote class and this was the closest thing available. I also don’t believe the Fast Track class is updated to 6.2, but I could be wrong.
- However, this was a VERY good class that laid out many of the fundamentals I needed.
- My instructor was good and even went over cross-vCenter vMotion and some of the changes for 6.2, which was not in the curriculum but very valuable.
- Moreover, when I take any kind of class, I screenshot EVERY slide and write notes the instructor states. I reviewed ALL of this material for my exam preparation.
- Labs, labs, labs. I can’t stress this enough – PLUS IT’S FREE!!!
- A few labs I did over and over again – mostly focused on the 1725 labs:
- HOL-1725-SDC-1 – VMware NSX Advanced Consumption
- HOL-1725-USE-2 – VMware NSX Multi-Site DR with SRM
- HOL-1703-SDC-1 – VMware NSX: Introduction and Feature Tour (while I did this in my class, it was a good refresher)
- HOL-1703-USE-2 – VMware NSX: Distributed Firewall with Micro-Segmentation
- VMware Hands on Lab Link: http://labs.hol.vmware.com/HOL/catalogs/catalog/681
- Since I deal with vCloud Director, I had a prebuilt vCD/NSX environment so I tested several scenarios also. However, the HOL give great guidance
- I used Gregg Robertson’s blog as an addition to my overview – I went through the podcasts but did not read the book he referenced. Many thanks to Gregg for this insight.
- Link: Gregg Robertson’s Blog on VCP-NV Test
- READ THE DANG PRODUCT DOCUMENTATION!
- This can’t be stressed enough. Even though it is long, some parts boring, there was some VERY VALUABLE insight, especially on the cross-vCenter vMotion setup and considerations.
- Docs I really focused on:
- VMware NSX Network Virtualization Design Guide – VERY IMPORTANT
- NSX Installation Guide
- NSX Administration Guide
- Cross-vCenter NSX Installation Guide
- Furthermore, with the admin guides – I took the labs and went through the basic administrative functions so I’m aware of steps.
- VMware VCP6-NV (2v0-642) 6.2 Practice Exam
- This was good – but obviously take it with a grain of salt. You can’t just take this expect to pass the test.
- Link to VMware myLearn VCP6-NV 6.2 Practice Exam
- I’m someone that needs to write/type things out and make a mental map of the technology and components. Therefore, I created this note sheet that I typed up a few days before the test: 2v0-642-UNOFFICIAL-StudyNotes
- PLEASE take these notes as they are – it’s my (weird) way of studying for a test and how I interpret NSX.
- I went through the test and flagged questions I was not entirely sure.
- First pass took me maybe 35 minutes to complete – then I went to the beginning and went through the test again, focusing on the flagged questions I wasn’t too sure of.
- Read each question CAREFULLY and eliminate the ones you know aren’t true.
- Overall, I think I finished up with 45 to 50 minutes to spare.
Overall, I thought the test was challenging and asked very fair questions. It also made me kick myself on things I should have reviewed further – but that’s what a test is!
I’ll be working on my VCAP next – TBD if I’ll switch over to DCV or stay on NV. But I truly enjoyed the experience and look forward to the next test preparation.
Thank you for visiting my new fangled blog. I’ll be discussing quite a few things in the tech and firearms industry.
Stay posted for a vCloud Availability for vCloud Director post soon – getting quite a bit of exciting feedback. I also recently passed my VCP6-NV so I’d like to discuss my study curriculum and what I believe it took to pass the test.
