Just this week I had to create a JSON object that contained all of the workflow input parameters and their respective values. While I can’t guarantee this is the best way to do it, it definitely works. I’ve tried to keep the comments succinct so if you have any questions please ask. Code // Get all input parameters for the parent workflow var inParamsArray = workflow.rootWorkflow.inParameters; // Get all input parameters for the current workflow to search through later var paramFinder = workflow.

One of the core pre-requisites for vCloud Availability for vCloud Director 2.0 is CassandraDB. This database service stores replication state and storage information and is used by the HCS (vSphere Replication Cloud Service) appliance. As part of my strained vCloud Availability deployment I needed to build a simple CassandraDB server. VMware Docs and the vCloud Architecture blog have some great information to get you started: vCloud Architecture blog - Deploying CassandraDB VMware Docs - vCloud Availability for vCloud Director Installation Guide Symptom I built the CassandraDB server as described in the blog post and Docs pages above, but when I would try to connect to the database using the Cassandra shell (cqlsh {ip-address} 9042) I would get the following error:

After a short break over Christmas and New Year’s I threw myself into the latest version of vCloud Availability for vCloud Director (2.0). The installation of vCloud Availability for vCloud Director (vCAv) is all done through an “installer appliance”, a CLI and a configuration file called a ‘registry’. I opted for the ‘automated’ installation using a registry file and had all of my configuration and VM deployment specs in there.

Here are some of the resources that I worked through as study material for the VCAP6-Design exam. A lot of these links and the discovery of these links can be attributed to a lot of others, and I’ll try to credit them where I can. vBrownBag EMEA - VCAP6-DCV Design - vBrownBag YouTube channel Some great presenters here that highlight some of the key concepts and follow up with discussions vThing - VCAP Study Resources - Andres Herceg’s blog https://vthing.

After months of studying and a Design and Deploy course for good measure, I passed the incredible VCAP6-DCV Design exam! This certification in combination with my VCAP5-DCA from 18 months ago has awarded me the VCIX6 title which I’m incredibly proud of. Here’s the official link from VMware about the certification: https://mylearn.vmware.com/mgrReg/plan.cfm?plan=89125&ui=www_cert To give you an idea of what the Design exam is about, take a look at https://www.virtualtiers.net. That exam simulator is a great representation of how the exam is formatted and how you’re tested.

Hello again! Today’s adventures drove me a little wild… Some background first. In my test environment, I have a full vCloud Director v8.10.1 deployment, load balanced with an F5 LTM. The certificates are loaded on the F5 so that traffic is terminated and re-encrypted on it’s way to the vCloud cells. Since deployment, both the http and console FQDNs functioned as expected. This all changed just a few months ago…

After a very successful and quick migration from Windows SSO 5.5 U3e installation to a Platform Services Controller v6.0U3 appliance I was ready to get my VMCA into action. We have a corporate internal Microsoft CA with the VMware certificate templates already created as per VMware KB 2112009. Everything was coming up Milhouse, until CSR generation time using the ‘certificate-manager’ on the PSCs. After stepping through the ‘certificate-manager’ wizard and having the CSR and private key files sent to a directory of my choosing, I quickly inspected the CSR using openssl to make sure I was on the right track:

After performing the vSphere v5.5 to vSphere 6.0 migration in our testing environment with great success, I began work on our production environment. First things first, migrating Windows SSO to PSC appliance. I had successfully converted the first machine, and started doing some testing. Things like logging into the thick client and checking all vCenter servers and basic login services. Problem Out of 6 vCenter servers, only 1 was having issues.

While trying to troubleshoot another problem, we tried Refreshing vCloud to vCenter which includes registering/updating the extension. This is when we hit a beauty we’d never seen before: Alright, calm down. Probably something with the network, right? And if it’s not the network then it’s probably DNS. Right? Oh how I wish that were so. I dug around in the vCenter MOB and found the vCloud Director extension. As expected it already had a “vCloud Director-1” named extension.

Roughly 2 weeks ago one of our vCloud Director tenants reported an error when attempting to increase a disk on their VM. They were told to contact their cloud administrator (yay). When we tried to perform the increase, we received an error we’d never seen before: “java.lang.NullPointerException”. Here is what we checked: Confirm the tenant Org vDC has the appropriate resources available (this was an ‘Allocation’ style vDC). Check the status of vCloud to vCenter connection and perform a vCenter Reconnect followed by a Refresh.
