Storage Migrate a vCloud Director VM using Rest API

If you are using vCloud Director in your environment and if you have ever tried doing a Storage vMotion of a VM from vSphere directly, you will notice a warning saying that its not recommended to modify the entity since its managed by VCD.

This is because of the the fact that with VCD, the management layer lies with itself and not with vSphere. All changes to the entities should be made via vCD and not vSphere.

Although doing a storage migration will not break anything but as a best practice we should avoid that.

So what to do if one of your backend LUN is full and you need to evacuate that by migrating some vm’s to another datastore which have enough free space. The answer is by using “Rest API”.

About the VMware vCloud API

The VMware vCloud API provides support for developers who are building interactive clients of VMware vCloud Director using a RESTful application development style.… Read More

Exploring vSphere 6.5 API-Part 2: Virtual Machines

In last post of this series we looked into some basic Rest API’s to fetch info about datacenter and cluster.

In this post we will explore API options for virtual machines. Out of all the components like host, cluster etc, max number of available API options are for virtual machines.

Let’s start with figuring out available options:

To start exploring the different API options available for virtual machine, you can use below query:

1: List all VM’s in all datacenter

Output of above query will give you VM ID, cpu/memory stats, VM name and their power status.

2: List Powered off VM’s

You can list all powered off VM’s in datacenter using the filter power_states in above query.… Read More

Exploring vSphere 6.5 API-Part 1: Datacenter & Cluster

I am using API for quite a bit now in our prod environment which is based on vCloud Director and many times API’s had proved a handy way to troubleshoot issues where GUI was not providing a way to proceed.

Inspired by vCD API’s, i decided to test that in my vSphere 6.5 lab and in this post I will try to demonstrate few queries which can be helpful in fetching info in your infrastructure.

In my lab I am exploring REST API’s using a linux tool called curl.

1: You can browse list of API’s by browsing https://vcenter-fqdn/ and clicking on “Browse vSphere Rest API’s”

 

2: To start with you can use below query to see what are the different options available

# curl -sik -H ‘Accept:application/json’ -u “vc-user” -X GET https://vcenter-fqdn/rest/

You will see below URL’s in output:

3: You can list the available components which can be explored via REST API by using below query

# curl -sik -H ‘Accept:application/json’ -u “vcadmin@alex” -X GET https://vcentersrv03.alex.local/rest/com/vmware/vapi/rest/navigation/componentRead More

Learning vSphere 6.5-Part-10-VCHA failover testing

Last 2 post of this series were revolving around the high availability feature for vCenter that is introduced in vSphere 6.5 and we discussed the VCHA architecture and also learnt how to configure VCHA.

In this post we will be testing the HA feature and will see what happens when the Active Node of VCHA cluster goes down.

If you have missed earlier post of this series, you can read them from below links:

1: Installing and Configuring Esxi

2: VCSA Overview

3: vCenter Server and PSC Deployment Types

4: System Requirements for Installing vCenter Server

5: Installing vCenter Server on Windows

6: Deploying vCSA with embedded PSC

7: Deploying External PSC for vCSA

8: Understanding vCenter Server High Availability (VCHA)

9: Configuring vCenter Server High Availability (VCHA)

Lets jump into lab and test this awesome feature.

We will be testing failover via 2 method:

  • Automated failover (let system do the magic)
  • Manual failover (user will intentionally bring down active node of VCHA cluster)

Automated Failover Testing

1: To test the failover, login to vCenter web client and navigate to Configuration > vCenter HA and before performing a failover look at the Active/Passive node info and note which IP is active at the moment.… Read More

Learning vSphere 6.5-Part-9-Configuring vCenter Server High Availability (VCHA)

In last post of this series we discussed about the High Availability feature for vCenter 6.5 and saw the architecture of VCHA and how it works. In this post we will go ahead and actually configures that in lab.

If you have missed earlier post of this series, you can read them from below links:

7: Deploying External PSC for vCSA

8: Understanding vCenter Server High Availability (VCHA)

Before jumping into lab and start configuring VCHA, its important to understand the deployment options and prerequisites  for VCHA first.

vCenter HA Deployment Options

You can set up your vCenter HA environment with an embedded PSC or with an external PSC. If you decide to use an external Platform Services Controller, you can place it behind a load balancer for protection in case of Platform Services Controller failure.… Read More

Learning vSphere 6.5-Part-8-Understanding vCenter Server High Availability (VCHA)

In last post of this series learned how to External PSC for vCSA. In this post of vSphere 6.5 series, we will look into one of the best feature which is included in v 6.5 i.e high availability for vCenter Server.

If you have missed earlier post of this series, you can read them from below links:

1: Installing and Configuring Esxi

7: Deploying External PSC for vCSA

Customers were demanding a lot for high availability solution for vCenter Server for quite some time and VMware listened to customers and made this happen in version 6.5 of vSphere.

What is vCenter High Availability (VCHA)?

vCenter High Availability (vCenter HA) protects vCenter Server Appliance against host and hardware failures. The active-passive architecture of the solution can also help you reduce downtime significantly when you patch vCenter Server Appliance.… Read More

Learning vSphere 6.5-Part-7-Deploying External PSC for vCSA

This is part 7 of the vSphere 6.5 learning series and in last part of this series we learned how to install vCSA with embedded PSC and touched on some basic settings which is needed to be done post deployment.

In this post we will learn how to deploy external PSC for vCSA. The goal here is to deploy external PSC first and then install vCSA which will use the external PSC.

If you have missed earlier post of this series, you can read them from below links:

1: Installing and Configuring Esxi

In last post we discussed and saw how easy VMware has made deployment process of vCSA and the process has changed a bit. The steps needed to deploy external PSC is no different then what we learned in last post.… Read More

Learning vSphere 6.5-Part-6-Deploying vCSA with embedded PSC

In last post of this series we learnt how to install vCenter with embedded PSC on windows server.

In this post we will learn about deploying and configuring vCSA with embedded PSC.

If you have missed earlier post of this series, you can read them from below links:

1: Installing and Configuring ESXi

2: VCSA Overview

3: vCenter Server and PSC Deployment Types

4: System Requirements for Installing vCenter Server

5: Installing vCenter Server on Windows

In vSphere 6.5 VMware has made the installation of vCenter appliance a lot easier than before. Earlier, deployment of vCSA needed client integration plugin to be installed on your system and the deployment was done through a browser. Client integration plugin had multiple compatibility issues. Now with vSphere 6.5 client integration plugin is no longer required. The deployment is going to be via an ISO which would have an installation wizard that can be executed on Windows, MAC or Linux.… Read More

Learning NSX-Part-10-Upgrade NSX Manager From 6.2 to 6.2.4

This week I was trying my hands on upgrading NSX to version 6.2.4 which was released earlier this year in August.

I had no experience earlier with upgrading NSX manager and associated components, so I spent a lot of time in reading blogs and watching videos on how to perform the upgrade.

Before starting with upgrade process please consult the NSX 6.2.4 Release Notes and also follow VMware KB-2144295 which explains recommended minimum versions for VMware NSX for vSphere, ESXi, vCenter Server and Guest Introspection Driver (GID).

To keep track of latest versions you can use vTracker or the Latest Versions page hosted on www.virten.net

You can follow the below upgrade matrix to find out the upgrade path available in your environment.

While going through the blogs on how to start upgrading NSX to 6.2.4, I came across screenshot of a cool table which Anthony has posted on his Blog.… Read More
