I will not go into full detail in this blog post. Just a basic instruction on how to resolve the issue in vRealize Orchestrator 7.6. More background information can be found over here with additional screenshots.
Note: vRealize Orchestrator 7.6 was released on 11-04-2019 and can be downloaded over here. The vRealize Orchestrator 7.6 release notes can be found over here.
No Workflow Output
Let’s start with a small introduction to the issue. After an upgrade from vRealize Orchestrator 7.5 to vRealize Orchestrator 7.6 the (legacy client) is not able to show any workflow logs after executing a workflow run.
To make it perfectly clear… the workflow is executed and is working fine. The logs are just not displayed in the vRealize Orchestrator Client.
Here is an example, the workflow has been executed and it should output information but the logs tab is empty. Keep in mind: this image is from a vRO 7.4 instance but looks identical to vRO 7.6.
Restore the workflow output
Here are the commands for resolving the issue in vRealize Orchestrator ( vRO) 7.6 . The fix can be applied in under 10 minutes by a system administrator.
Before removing the files it is good practice to make sure you have a backup or virtual machine snapshot of your vRO appliance.
### Step 01: Start an SSH session with the vRealize Orchestrator Appliance (use for example Putty).
### Step 02: Login with root credentials
### Step 03: When you run the following command multiple files will be shown:
ls -l /var/log/vco/app-server/scripting.log_lucene*
### Step 04: Stop the Orchestrator service
service vco-server stop
### Step 05: Remove the log files
rm -rf /var/log/vco/app-server/scripting.log_lucene*
### Step 06: Start the Orchestrator service
service vco-server start
### Step 07: Open the vRealize Orchestrator Client
### Step 08: Execute a workflow and logging should be working again.
I have tested it so far on two vRealize Orchestrator 7.6 appliances that were upgraded from vRealize Orchestrator 7.5. In both cases the upgrade was successful but the workflow output was not working.
There might be some vRO 7.5 to vRO 7.6 upgrades that will work without issues… like an Orchestrator that is just sitting idle or maybe a clean install that is directly upgraded from 7.5 to 7.6?
If you got any comments or tips please respond below!
At a customer, I encountered the following issue when trying to connect with PowervRA to vRealize Automation. The error message that appeared was: Invoke-RestMethod : The underlying connection was closed: An unexpected error occurred on a send.
Let go one step back: So what is PowervRA you might ask? PowervRA is a PowerShell Toolkit to manage VMware vRealize Automation (vRA). With PowervRA you can configure and manage your vRealize Automation environment, for example, create a new tenant, assigning permissions or viewing the user’s requests.
The problem started by connecting with PowervRA to vRealize Automation (vRA). There was no way to get a successful connection. I tried using the IP addresses, hostname and FQDN also different credentials didn’t make any difference. The error that returned in all cases was identical.
The customer was using the latest version of PowervRA. At this moment it was PowervRA 3.5.0. The vRealize Automation version they were using was 7.4.0.
Here is the screenshot of the error message:
Here is the full error message in plain text from the PowerShell Console:
Invoke-RestMethod : The underlying connection was closed: An unexpected error occurred on a send.
At C:\Program Files\WindowsPowerShell\Modules\PowervRA\3.5.0\PowervRA.psm1:510 char:21
+ $Response = Invoke-RestMethod @Params
+ CategoryInfo : InvalidOperation: (System.Net.HttpWebRequest:HttpWebRequest) [Invoke-RestMethod], WebException
+ FullyQualifiedErrorId : WebCmdletWebResponseException,Microsoft.PowerShell.Commands.InvokeRestMethodCommand
To validate the issue further I tried the same thing in my Lab environment. The strange thing was that everything was working fine with the identical versions.
Until this moment I am not really sure why it is working in one environment and not in the other… I suspect it has something to do with Windows Updates or Domain Security Policies? To address the issue there is only one way: force PowerShell/PowervRA to use TLS 1.2 when connecting with vRealize Automation (vRA).
Open the PowerShell command-prompt as administrator.
Run the following command before connecting to vRealize Automation. The command is listed below. No output is expected after running this command.
Run the Connect-vRAServer PowerShell command to start a session with vRealize Automation. Everything should be working and authentication should be possible.
Copy and paste the code into your PowerShell console before connecting to vRealize Automation:
I ran into an error message today with vRealize Automation (vRA). The error message that came up was: Failed to convert external resource Prod-Fin-00012. The issue occurred in vRA version 7.3.1.
Inside the vRealize Automation portal, I tried to upgrade virtual machine hardware but it failed directly when issuing the request. Strange thing was it was working a couple of day ago. After some investigating the error also came back on other day-2 tasks. So it was time to dive deeper into the issue.
Here is a screenshot of the issue:
So let us think about what vRealize Automation is performing, it is executing a task on a virtual machine. To perform this it needs to talk to vCenter Server and to talk to vCenter Server it uses vRealize Orchestrator.
Here is a simple overview of the communication that happens in this case. vRealize Automation is communicating to vRealize Orchestrator and vRealize Orchestrator is communicating to vCenter Server.
The following error messages were found on the following systems:
https://LAB-VC-A.Lab.local:443/sdk (unusable: java.lang.ClassCastException: com.vmware.vcac.authentication.http.spring.oauth2.OAuthToken cannot be cast to com.vmware.vim.sso.client.SamlToken)
As you can see here vRealize Orchestrator has communication issues with VMware vCenter Server. This issue needs to be addressed for vRealize Automation.
After finding the vRealize Orchestrator vSphere endpoints in an error state it was clear that this was the issue. vRealize Orchestrator is not successfully communicating with vCenter Server so this needs to be addressed.
Open the vRealize Orchestrator Client (https://%vro-node-fqdn%).
Login with administrative credentials (example: firstname.lastname@example.org).
Navigate to the following location “Library > vCenter > Configuration“.
Run the following workflow “Remove a vCenter Server instance” (screenshot 01 & screenshot 02).
Run the following workflow “Add a vCenter Server instance” (screenshot 03 & screenshot 04).
Validate the vRealize Orchestrator Endpoint Status (screenshots 05).
Lately, I encountered some issues related to VMware vSAN in my Lab environment. The error message that was popping up all the time was “PBM error occurred during PreCloneCheckCallback“.
So how did the problem occur? First, we start with some background information. My Lab environment is powered-on when needed and powered-off when not needed. This is, of course, a little bit different than a production 24×7 environment that you have in your datacenters worldwide.
The environment was booted successfully at first glance. We are talking about Domain Controllers, vCenter Server, VMware NSX-V, nested ESXi Hosts and vRealize Automation. When I started deploying virtual machines with a vRealize Automation (vRA) based on blueprints with vSphere Templates issues started to occur.
vRealize Automation was failing on the provisioning task and was cleaning up the deployment because of the failed state (default behavior). So it was time to dig into the underlying infrastructure.
When the issue occurred the following software versions were used in my lab environment:
VMware vCenter 6.5 Update 2B
VMware vRealize Automation 7.3.1
VMware ESXi 6.5 Update 2
VMware vSAN 6.6
Here is all the information that can be found in various locations surrounding the issue.
Error message: Screenshots
Here are the screenshots, the first one is from VMware vCenter and the second one is from vRealize Automation. As you can see there is clearly a problem.
Error message: vRealize Automation
Here is the vRealize Automation log entry related to the VMware vSAN issue:
Error in Execute DynamicOps.Common.Client.HtmlResponseException: Service Unavailable (503)
Error message: vCenter Server
Here is the VMware vCenter log entry related to the VMware vSAN issue:
A general system error occurred - PBM error occurred during PreCloneCheckCallback (2118557)
The solution is quick but is more like a quick fix because it comes back every time I start up my lab environment.
Open a web browser.
Navigate to your vCenter Server URL (https://%vc%/vsphere-client).
Login with a user that has administrator credentials (email@example.com).
Navigate to Hosts & Clusters > Select the vCenter Object.
Click on the Configure tab.
Click on the Storage Providers.
Click on the following two buttons:
Synchronizes all Storage Providers with the current state of the environment.
Rescan the storage provider for new storage systems and storage capabilities.
After pressing the buttons, you don’t see any tasks running on the vCenter Server (expected behavior). After 5 seconds everything should be working and provisioning should be possible.
This time I decided to do a blog post about the HPE Smart Array RAID controllers with their wonderful ssacli tool. The tooling of HPE is very powerful because you can online manage a VMware ESXi host and migrate for example from a RAID 1 volume to a RAID 10 without downtime or change the read and write cache ratio.
So far as I know I haven’t seen an identical tool yet from the other server hardware vendors like Cisco, Dell EMC, IBM, and Supermicro. The main difference has always been that the HPE tool can perform the operation live without downtime.
So far as I can remember it has been there for ages. It was already available for VMware ESX 4.0 and is still available in VMware ESXi 6.7. So thumbs-up for HPE :).
Let’s talk about controller support. The tool supports the most HPE SmartArray controllers over the last 10 to 15 years, for example, the Smart Array P400 was released in 2005 and is still working fine today.
Here is an overview of supported controllers:
HPE Smart Array P2XX
HPE Smart Array P4XX
HPE Smart Array P7XX
HPE Smart Array P8XX
HPE SSACLI – Location
In case you are using the HPE VMware ESXi custom images. The tool is already pre-installed when installing ESXi. The tool is installed as a VIB (vSphere Installable Bundle). This means it can also be updated with vSphere Update Manager.
Over the years the name of the HPE Storage Controller Tool has been changed and so has the location. Here is a list of locations that have been used for the last ten years for VMware ESXi:
I have collected some screenshots over the years. Screenshots were taken by doing maintenance on VMware ESXi servers. The give you an idea what valuable information can be shown.
HPE SSACLI – Abréviation
All commands have a short name to reduce the length of the total input provided to the ssacli tool:
- chassisname = ch
- controller = ctrl
- logicaldrive = ld
- physicaldrive = pd
- drivewritecache = dwc
- licensekey = lk
### Specify drives:
- A range of drives (one to three): 1E:1:1-1E:1:3
- Drives that are unassigned: allunassigned
HPE SSACLI – Status
To view the status of the controller, disks or volumes you can run all sorts of commands to get information about what is going on in your VMware ESXi server. The extensive detail is very useful for troubleshooting and gathering information about the system.
# Show - Controller Slot 1 Controller configuration basic
./ssacli ctrl slot=1 show config
# Show - Controller Slot 1 Controller configuration detailed
./ssacli ctrl slot=1 show detail
# Show - Controller Slot 1 full configuration
./ssacli ctrl slot=1 show config detail
# Show - Controller Slot 1 Status
./ssacli ctrl slot=1 show status
# Show - All Controllers Configuration
./ssacli ctrl all show config
# Show - Controller slot 1 logical drive 1 status
./ssacli ctrl slot=1 ld 1 show status
# Show - Physical Disks status basic
./ssacli ctrl slot=1 pd all show status
# Show - Physical Disk status detailed
./ssacli ctrl slot=1 pd all show status
# Show - Logical Disk status basic
./ssacli ctrl slot=1 ld all show status
# Show - Logical Disk status detailed
./ssacli ctrl slot=1 ld all show detail
HPE SSACLI – Creating
Creating a new logical drive can be done online with the HPE Smart Array controllers. I have displayed some basic examples.
# Create - New single disk volume
./ssacli ctrl slot=1 create type=ld drives=2I:0:8 raid=0 forced
# Create - New spare disk (two defined)
./ssacli ctrl slot=1 array all add spares=2I:1:6,2I:1:7
# Create - New RAID 1 volume
./ssacli ctrl slot=1 create type=ld drives=1I:0:1,1I:0:2 raid=1 forced
# Create - New RAID 5 volume
./ssacli ctrl slot=1 create type=ld drives=1I:0:1,1I:0:2,1I:0:3 raid=5 forced
HPE SSACLI – Adding drives to logical drive
Adding drives to an already created logical drive is possible with the following commands. You need to perform two actions: adding the drive(s) and expanding the logical drive. Keep in mind: make a backup before performing the procedure.
# Add - All unassigned drives to logical drive 1
./ssacli ctrl slot=1 ld 1 add drives=allunassigned
# Modify - Extend logical drive 2 size to maximum (must be run with the "forced" flag)
./ssacli ctrl slot=1 ld 2 modify size=max forced
HPE SSACLI – Rescan controller
To issue a controller rescan, you can run the following command. This can be interesting for when you add new drives in hot swap bays.
### Rescan all controllers
HPE SSACLI – Drive Led Status
The LED status of the drives can also be controlled by the ssacli utility. An example is displayed below how to enable and disable a LED.
# Led - Activate LEDs on logical drive 2 disks
./ssacli ctrl slot=1 ld 2 modify led=on
# Led - Deactivate LEDs on logical drive 2 disks
./ssacli ctrl slot=1 ld 2 modify led=off
# Led - Activate LED on physical drive
ctrl slot=0 pd 1I:0:1 modify led=on
# Led - Deactivate LED on physical drive
ctrl slot=0 pd 1I:0:1 modify led=off
HPE SSACLI – Modify Cache Ratio
Modify the cache ratio on a running system can be interesting for troubleshooting and performance beanchmarking.
# Show - Cache Ratio Status
./ssacli ctrl slot=1 modify cacheratio=?
# Modify - Cache Ratio read: 25% / write: 75%
./ssacli ctrl slot=1 modify cacheratio=25/75
# Modify - Cache Ratio read: 50% / write: 50%
./ssacli ctrl slot=1 modify cacheratio=50/50
# Modify - Cache Ratio read: 0% / Write: 100%
./ssacli ctrl slot=1 modify cacheratio=0/100
HPE SSACLI – Modify Write Cache
Changing the write cache settings on the storage controller can be done with the following commands:
Viewing or changing the rebuild priority can be done on the fly. Even when the rebuild is already active. Used it myself a couple of times to lower the impact on production.
# Show - Rebuild Priority Status
./ssacli ctrl slot=1 modify rp=?
# Modify - Set rebuildpriority to Low
./ssacli ctrl slot=1 modify rebuildpriority=low
# Modify - Set rebuildpriority to Medium
./ssacli ctrl slot=1 modify rebuildpriority=medium
# Modify - Set rebuildpriority to High
./ssacli ctrl slot=1 modify rebuildpriority=high
HPE SSACLI – Modify SSD Smart Path
You can modify the HPE SDD Smart Path feature by disabling or enabling. To make clear what the HPE SDD Smart Path includes, here is a officialstatement by HPE:
“HP SmartCache feature is a controller-based read and write caching solution that caches the most frequently accessed data (“hot” data) onto lower latency SSDs to dynamically accelerate application workloads. This can be implemented on direct-attached storage and SAN storage.”
In this post, we are going to change the Virtual Storage Controller from LSI Logic Parallel to VMware Paravirtual for a CentOS 7 based Virtual Machine that is running on VMware vSphere. This blog post will contain step by step guidance for performing the operation.
In my case the virtual machine was build in VMware Workstation and after some time migrated to VMware ESXi. The VMware Paravirtual Storage Controller is not supported in VMware Workstation. That is why the virtual machine came over with the “wrong” storage controller.
My 24×7 Lab environment is running shared iSCSI based storage and all virtual machines are thin provisioned. The Virtual Machine that came over from VMware Workstation is installed with CentOS 7.
Why VMware Paravirtual?
Why should you want to migrate from an LSI Logic Parallel to a VMware Paravirtual SCSI Controller? Two simple reasons and they are two good ones:
Lower CPU utilization
Personally, I have a third reason to add… compliance. All my virtual machines should be compliant with the VMware Best Practice and my personal Home Lab standard. In my Lab environment, this means using the VMware Paravirtual where ever possible/supported.
Assign disks to the new storage controller and remove the old storage controller (screenshot 03).
Power-on the virtual machine.
Validate that everything is working and disks are mounted (screenshot 04).
Remove the virtual machine snapshot or backup after you are done.
Here are some screenshots from the procedure:
At this point, I have swapped out three virtual machines from the LSI controller to the VMware Paravirtual SCSI Controller. The machines have been running now for about two weeks without any problems. So everything is compliant again ;).

Here are some interesting related articles that I used for creating this blog post:
In this blog post, we are going to deploy VMware vCenter 6.7 Update 1 in my Lab environment. The deployment is fully covered with all the additional notes required to perform a successful installation, migration or upgrade. I also added some guidelines for designing your environment.
If you are familiar with the VMware vCenter 6.5 graphical deployment it has been improved in VMware vCenter 6.7. In the past it was a web-based wizard, with 6.7 it is a binary executable. This means a lot faster and better-responding interface and it removes the browser dependency and browser plug-in on your workstation.
The checklist items can be verified, days or hours before the initial deployment. If you don’t have a plan before installing, migrating or upgrading things will turn out ugly…
With the checklist, you can determine if your environment is ready for vSphere 6.7 Update 1. It’s about checking and validation your current software and hardware and talking to your vendors about compatibility.
I have also added some design decision ideas. Because you can choose to install, upgrade or migrate without looking at your current architecture but maybe it is time to update your current architecture (design).
Make sure that all connected/used VMware products are compatible like (vRealize Automation / vRealize Orchestrator / vRealize Operations Manager / VMware Horizon and the list goes on). This can be verified on the VMware Product Interoperability Matrices page.
Make sure that all third-party products are compatible like (Backup & Replication software / Storage vendor software).
Determine the correct sizing for your environment. How many virtual machines and ESXi Hosts are going to be running underneath this vCenter Server. These figures determine your vCenter Server size.
Download the latest release from the VMware website.
Create firewall rules for your new vCenter Server.
Create forward and reverse DNS records in your DNS Server.
Register your IP information in your IPAM system.
Save your passwords in your Password Management system (Appliance password / SSO password).
Have a workstation ready to perform the deployment with sufficient network access and administrative rights.
Let’s start the deployment of VMware vCenter 6.7 Update 1. I have chosen for a clean installation of VMware vCenter 6.7 Update 1. I have chosen for an embedded Platform Services Controller (PSC). Based on my total amount of virtual machines and ESXi Hosts I have selected a “Small” installation footprint.
The new deployment process for vCenter Server 6.7 Update 1 consists out of two stages, one is the deployment stage and one is the setup stage.
The first part is mainly responsible for delivering the full appliance with the operation system, network settings, and installation application bundles. The second part is configuring the applications that are running on the vCenter Server. A total installation takes about 45 minutes to complete.
Mount the vCenter Server media (iso file).
Navigate to the following path “X:\vcsa-ui-installer\win32\” (X stands for the CD-ROM drive label).
Run the following application “installer.exe“.
Follow the wizard, I have uploadedall screenshots for reference.
Stage 01 – Deployment
Here are the images of the first stage of the deployment of VMware vCenter 6.7 Update 1. I have no issues to report everything was working fine on the first try!
Stage 02 – Setup
Here are the images of the second stage of the deployment of VMware vCenter 6.7 Update 1. This part was also bug-free, so it was a good deployment.
After a successful deployment of the VCSA appliance, you need to configure at least some items to get vCenter Server production ready. The items listed below are a basic set of the most common items I see in the field:
Install the vCenter Server License.
Assign rights & permissions.
Generate and installation of SSL Certificates.
Connect the required VMware products and third-party systems.
VMware vCenter 6.5.0 Update 2. The target for the vCenter 6.7.0 Update 1 deployment.
VMware ESXi 6.5.0 Update 2 in the 24×7 environment. Known as the production cluster.
VMware ESXi 6.5.0 Update 2 in the Lab environment. Known as the lab cluster.
You might ask… why don’t you upgrade the current vCenter Server? Good question! The machine has been converted/upgraded multiple times. It started out in life as a VMware vCenter 5.5 machine, that was on the Windows Server 2012 platform. So it was a good moment to start clean after this many years.
How to upgrade vRealize Orchestrator 7.4 to vRealize Orchestrator 7.5 or to be more precise… migrate! Since the release of vRealize Orchestrator 7.5 a couple of weeks ago the update/upgrade option with the vamicli and appliance management interface is not available (to my surprise).
A quick introduction to how I got in that situation: In my Home Lab my main vRealize Orchestrator appliance is running version 7.4.0 and is responsible for some day-to-day Orchestration of my multiple environments.
For the people that are is still running way older versions: Upgrading vRealize Orchestrator Appliance from version 5.5.x to 7.5 is not supported. You must upgrade your vRealize Orchestrator Appliance 5.5.x to 6.0.x first and then migrate to 7.5.
The following components were running in my environment and have been tested. Note: this part of my Lab environment is not running vRealize Automation. So I have not tested the migration with external vRO nodes in combination with vRealize Automation.
A single vCenter Server 6.5.0 Update 2 (with an embedded PSC)
A single vRealize Orchestrator 7.4.0 (external)
There are two options available. The first option is moving all data between the old and new vRealize Orchestrator. The second option is to migrate vRealize Orchestrator with the migration wizard. The second option is the one VMware recommends. The first option can be easier in some cases, some advantages are you retain your IP address, hostname and SSL certificates.
Both options are written down on this page.
vRO export data and redeploy
I have chosen for this scenario because this machine is only connected to a vCenter Server and can be reastablished very fast. Another reason is that the current vRO instance has been running since version vRO 7.0 and has been upgraded more than seven times in about 2.5 years. So a new clean install ain’t a bad thing!
Create a package in the vRealize Orchestrator Client with all your created workflows, actions and resource elements.
Save the package on a save place.
Remove the registration from vCenter Server (if they are connected). Workflows “Unregister a vCenter Server extension” & “Remove a vCenter Server instance“.
Poweroff the current vRO appliance.
Rename the appliance to %vm-name%.old (for example).
Deploy a new vRealize Orchestrator Appliance on the same IP address and FQDN.
Upgrade the virtual hardware.
Walkthrough the vRealize Orchestrator configuration wizard.
(Optional) install the SSL certificates.
Import the package.
Register with vCenter Server. Workflows “Add a vCenter Server instance” & “Register vCenter Orchestrator as a vCenter Server Extension“.
The migration path is performed in the following way (the official documentation is extensive, the link is listed below). The migration is a good option for an Orchestrator that is connected to a lot of extensibility and has a lot of plugins installed. The biggest issue for me was the new IP address, FQDN and new certificates required.
Note: Migrations with vRealize Orchestrator Clusters are not described here. There are a couple of small items you need to check in the migration manual.
Your source Orchestrator is running at least version 6.X.
Make sure no workflows are running.
Stop the Orchestrator services on the source Orchestrator.
Make sure SSH is enabled on both the source and destination Orchestrator.
Make sure no firewall is blocking traffic for the migration.
Create backups from the source and destination Orchestrator.
Register a new vRealize Orchestrator appliance in your IPAM solution.
Deploy a new vRealize Orchestrator next to the currently running.
Upgrade Virtual Machine Hardware
Power-on the vRealize Orchestrator appliance.
(Optional) Install new SSL Certificates.
Navigate with a browser to the Appliance Management interface (https://%FQDN%:5480).
This year VMworld 2018 Europe is held in Barcelona Spain from 5 November until 8 November. This has been the location for some time now. Only the date shifted a couple months backward compared to last year (September > November). This page will be updated multiple time in the coming days. I will add additional information and announcements multiple times a day.
I was able to attend myself in person thanks to my employer ITQ. This year we traveled with 33 ITQ colleagues to VMworld 2018 Europe. In total 12000 people attended VMworld 2018 Europe in Barcelona.
VMworld 2018 EU – Product Announcements
On VMworld 2018 in Europe, the following products and/or services were announced.
VMware Cloud Foundation (VCF) 3.5
In the opening keynote VMware Cloud Foundation (VCF) 3.5 has been released.
VMware Cloud Foundation is an automated release of the Software-Defined Datacenter with vSphere, NSX, and vSAN in the core. On top VMware is using there vRealize Suite for creating an entire Cloud Management Platform.
The VCF 3.5 release includes the following new features:
Clarity UI as for all VMware products.
More intuitive end-to-end UI driven workflows
Improved UI responsiveness and performance
Dashboard with widgets to more easily surface important SDDC information
Updated navigation and consistency between workflows
Extendable platform to ensure that we can incorporate new releases and functionality (ex. New workflow wizards, dashboard widgets)
Just like every year, William Lam from the website virtuallyGhetto creates a GIT repository with all the VMworld sessions. For each session, a recording and presentation is provided on his Git Repository. It will probably be a couple of days till weeks until all sessions become available:
This week we (Vincent van Vierzen and myself) attended the vRO Master Class that was offered to us by our employee ITQ. It is a three-day course on-site in the VMware UK HQ in Staines. The class was attended by seventeen people from all over the EMEA region. Keep in mind: the Livefire courses are only available to VMware employees and VMware partners. The information shared at the Livefire is protected by the VMware NDA, so no information is covered here that will break the NDA.
Before we went to the vRO Master Class course we didn’t know what to expect. A couple of questions that went through our heads were: What would the expected technical level be? What items would be discussed and explained? Is it a theoretical or hands-on course?
On the first day, we got access to a dedicated HOL environment that has been build for the vRO Master Class and the vRealize Orchestrator history and architecture is explained. There was also a lot of talk about the new and coming features for vRealize Automation (vRA) and vRealize Orchestrator (vRO).
Day two was about Dynamic Types and the APIs available in vRealize Automation & vRealize Orchestrator. Christophe explained some projects he has done and blogged on his one website. There was just a lot of information available first hand.
Day three was about vRealize Orchestrator best practices. The best practices slides were extensive and were covering all the aspects. Examples were workflow performance and troubleshooting. They also covered workflow and action development. In the afternoon Spas covered the integration with Microsoft PowerShell and his first-hand experience.
The vRO Master Class course covered the following use cases that were relevant for in the real world:
Create a bunch of VMs (vCenter plug-in)
Resume a failed workflow
Leverage the vAPI
Create a Dynamic Types plug-in from scratch
Create a plug-in with the Dynamic Types plug-in generator
Extend the vRealize Automation Lifecycle with Event Broker
vRA 7.4 – Create a blueprint with an IP input field (Custom Forms & Iaas plug-in)
vRA 7.3 – Create a blueprint with an IP input field (CBP, XaaS, vRA CAFE & IaaS plug-in)
Leverage Dynamic Types Microsoft DNS plug-in with XaaS and XaaS Blueprint components
Create scalable Photon Swarm Blueprint
Use vRA Scalable XaaS components
Simple Database Integration (SQL Plug-in)
Using PowerShell Credential Delegation in vRO
Leverage Guest Operations with Script Manager
Use the vRO REST API
As consultants, we were also interested in vCloud Director use cases and real-world examples but they will be included in the new vRO Master Class in 2019. So in case you are going for vCD stuff wait for 2019.
The following instructors can be available for the vRO Master Class. We were lucky to have Spas Kaloferov and Christophe Decanini available for the three days. Here is an overview of the vRO Master Class instructors:
The vRO Master Class is really focused on vRealize Orchestrator. You have to be a vRO guy definitely to join this class. We think it is a good thing that there is a course available that is purely focused on vRO because VMware Education is more or less focused on the entire CMP.
The instructors were really qualified and experts on vRealize Orchestrator. Christophe is one of the original Dunes Technologies employees that came over to VMware when the product was acquired in 2007. He knows all the ins and outs about the Orchestrator product and the history related to chooses that have been made over time.
The balance between talking about the material and spending time in the lab environment could be improved. The course should be extended with an additional day to a total of four days (at least). This will bring the course more into balance and it introduces more time for the attendees to spend time on the labs and get more hands-on experience out of the course.
Here is a list of interesting sources related to the vRO Master Class course:
