vRO 7.5 Upgrade/Migration - Failed to validate the source vRealize Orchestrator database.

I’ve got a standalone vRealize Orchestrator 7.4 instance in my test environment and with the release of vRealize Orchestrator 7.5 I wanted to run through the upgrade. If you haven’t noticed already, it’s a migration to a new appliance not an in-place upgrade. This means the new vRO instance will need to connect to the existing vRO appliance and pull all of the data. When I tried doing my migration/upgrade, I got the following error message during the validation phase:

Sending VM keystrokes using vRealize Orchestrator

Last year the legendary William Lam (Virtually Ghetto) posted a handy Powershell script that can use the vSphere 6.5 API’s to send keyboard key strokes to a VM (https://www.virtuallyghetto.com/2017/09/automating-vm-keystrokes-using-the-vsphere-api-powercli.html). I recently had a need for this feature but in vRealize Orchestrator and in Javascript instead of Powershell so I’ve re-written it in Javascript. I’ve included 2 additional script blocks that you can place into Scriptable Tasks or Actions too.

VclAbstractObjectValue - Unable to serialize object

I’ve been working on some automation that will create metadata against objects in vCloud Director using vRealize Orchestrator. If you’ve ever had to do this before you’ll know how painful it can be to get your head around all of the objects/transformations you need to make before you can even set the metadata to the object. First you take the metadata value (in this case a string) and create a new VclMetadataStringValue object.

vCloud Director metrics - unable to configure metric, conflicts with existing column

Recently I spent some time configuring vCloud Director metrics and storing them in a Cassandra cluster. If you have ever stepped outside of the default metrics and tried to provide your own via a Groovy file, you may have hit the following error in the cell-management-tool.log log: Invalid column name **metric** because it conflicts with an existing column If your Groovy file contains the metric listed in the error message and you’ve only listed it once, you’re probably thinking “where on earth is this duplicate coming from?

NSX Manager upgrade reports: Insufficient disk space

Have you got an NSX Manager that’s done the rounds for the past few years and served you well? Is it time for another upgrade but you’re stuck because the disk is full and you’ve been told: Cannot continue upgrade due to errors : Insufficient disk space. Database disk usage is at 87%, but it should be less than 70%. We recommend running a database full vacuum before proceeding with upgrade.

vRealize Operations Manager - Outbound REST Notification log location

A quick post today! I was trying to configure the vRealize Operations Manager Outbound REST notification plugin recently and I was having a few issues doing a POST or PUT operation against the specified endpoint. Specifically, I was getting the following message: Test was not successful: Failed to post or put to the server. I tried looking around the vROPs Logs section under Administration > Support > Logs but couldn’t find anything specific for Outbound Notification plugins.

Enumerate vRO Workflow Inputs into a JSON object

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.

CassandraDB Shell - Unable to connect to any servers

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:

vCloud Availability - vCD Gateway creation failed

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.

Studying for the VCAP6-Design DCV

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.
