vSphere SDK for JavaScript Fling released

02.03.2016 by William Lam // 2 Comments

The VMware Fling team has just released another cool new Fling, the vSphere SDK for JavaScript. This Fling is especially interesting as it provides the underlying SDK framework used by the popular ESXi Embedded Host Client Fling which was released back in August of last year. I came to learn about this project during last years internal R&D Innovation Offsite (RADIO) conference which is held annually and can be thought of as the VMworld conference for VMware employees.

One of the biggest highlight of the conference for me personally is checking out the expo floor where you get to see what other VMware Engineering teams have been working on whether it is the next big feature, product or new ideas that they might be thinking about. It was during my walk through that I met Rostislav Hristov, one of the Engineers who worked on the vSphere SDK for JavaScript. I was really impressed at what Rostislav built and luckily he was already in touch with the Embedded Host Client Engineers to see how they could leverage his JavaScript SDK as the initial prototype had made calls directly using the vSphere MOB which was not very friendly to develop against.

There has been a number of improvements to the vSphere SDK for JavaScript since I last saw it and although the name contains "vSphere", it definitely supports more than just the vSphere API endpoint. In fact, with this single SDK you can interact with vCenter Server Single Sign-On (SSO) API, vCloud Suite API which covers capabilities like Tagging and Content Library as well as the Site Recovery Manager (SRM) APIs! For customers and partners that are looking to develop their own web portals or interfaces that can integrate with these APIs, this will be a handy tool to have.

To get started, the vSphere SDK for JavaScript contains a README file that contains additional instructions on setting up the SDK as well as a couple of samples that demonstrates each of the supported API endpoints:

  • vimService.js - Sample using the vSphere API
  • stsService.js - Sample using the SSO API
  • cisServices.js - Sample using the vCloud Suite API
  • srmService.js - Sample using the SRM API

Here is the command to run the vimService.js sample which will also require you to set the environmental variable NODE_TLS_REJECT_UNAUTHORIZED=0 if you are using the default VMware self-signed SSL Certificate.

NODE_TLS_REJECT_UNAUTHORIZED=0 babel-node samples/vimService.js

vsphere-sdk-for-javascript-0
Once the sample has started up, you will be prompted with a URL to open in your browser. In the vimService.js example, you will be able to login to either a vCenter Server or ESXi host as seen in the screenshot below.

vsphere-sdk-for-javascript-1
Once logged in, you should see a simple listing of the different inventory objects in your vSphere enviornment.

vsphere-sdk-for-javascript-2
In the stsService.js sample, once logged in by specifying the address to your PSC/SSO instance, you should see that a SAML token was issued.

vsphere-sdk-for-javascript-3
The cisService.js sample exercises several operations using a mixture of both the vSphere API as well as the new vCloud Suite API. It does require connecting to a vCenter Server 6.0 environment as it will be performing operations using the new vSphere Content Library feature as well as some VM operations. Do not worry, once the operations have been completed, the script will automatically clean itself up. This is a great sample if you want to see how you could make use of the different APIs all through this single SDK.

vsphere-sdk-for-javascript-4-new
I did not have an SRM environment up and running to test the srmService.js sample, but you can see from the code that it will list all of the recovery plans and their current state. For more details on how the individual APIs work, you can refer to the documentation included in the vSphere SDK for JavaScript or the official API documentation for the individual products. If you have any feedback or comments about this Fling, please leave a comment on the Fling site here as I am sure the Engineers would love to hear what you think!

Windows Server 2012 fix is out for the VCS to VCSA Migration Fling!

01.05.2016 by William Lam //

Happy New Years everyone! Here is the first post of 2016 🙂

I know many of you have been anxiously waiting for a fix to the Winexe bug that causes the VCS to VCSA Migration Fling to fail when migrating from a vCenter Server that runs on Microsoft Windows Server 2012 (includes R2) OS to the VCSA. It has taken a bit longer than we all had hoped due to legal reviews and such, but today I am please to announce that we now have an updated release to the VCS to VCSA Migration appliance (v0.9.1). For customers using Windows Server 2012, WinRM will be used instead of Winexe due to the Windows bug that has been identified and will require a couple of additional configurations on the source Windows vCenter Server prior to starting the migration process. For more details, please refer to the documentation on the Fling site. Customers using Windows Server 2008, Winexe will continue to work as it does today.

In addition to this fix, we also now support specifying a custom port for the Microsoft SQL Server Database in case you had changed it from the default of 1433, which a few customers have asked for.

migration-applipance-0.9.1
I would like to give a big thanks to both Mike and Ravi for working tirelessly on getting this fix out as soon as they could along with all the legal hurdles. Let us know if you have any feedback by either leaving a comment below or better yet, interact with the Engineers by leaving a comment on the Fling site!

Upgrading ESXi itself is now possible with the new Embedded Host Client v4

12.21.2015 by William Lam // 13 Comments

It looks like we just got an early Christmas gift from Etienne, George and the VMware Flings team with the release of v4 of the ESXi Embedded Host Client (EHC). One of the new features that I am most excited about is the ability to upgrade ESXi itself using the "Update" feature which was first introduced in EHC v3. In the previous release of EHC, you could install or patch any ESXi VIB using this interface which I had blogged about here. With the latest release, Etienne has expanded its functionality to not only allow for a VIB URL but also a metadata.zip URL which ESXi offline bundles contain.

Here is an example of using EHC v4 to upgrade an ESXi 6.0 host to ESXi 6.0 Update 1:

Step 1 - Download ESXi offline bundle of choice, in this example we are downloading the offline bundle for ESXi 6.0 Update 1:updating-esxi-using-EHC-v4-1

Step 2 - You will need to extract the contents of the offline bundle and then upload the content to either a vSphere Datastore or an HTTP accessible URL as shown in the screenshots below.

updating-esxi-using-EHC-v4-3
Currently it is not possible to upload an entire directory using the Datastore Browser with EHC. This is something I have reported internally and hopefully will be fixed in a future update.

updating-esxi-using-EHC-v4-2
Step 3 - Click on the "Help" menu on the upper right hand corner of the Embedded Host Client and select the "Update" option which should prompt you to specify a URL. You can either specify a local datastore path to the metadata.zip such as the following:

/vmfs/volumes/datastore1/ESXi600-201510001/metadata.zip

or you can specify an HTTP(s) URL to the metadata.zip like the following:

http://192.168.1.180/ESXi600-201510001/metadata.zip

updating-esxi-using-EHC-v4-4
Step 4 - Once you click the "Update" button, you will be asked to confirm and then you should see task kicked off called "Install Host Patch V2". Once the task has completed, you will need to reboot the ESXi host for the changes to take effect. If you are interested in viewing the update logs without having to log in via SSH, you can click on the "Monitor" tab of the Host option and under "Logs", click on /var/log/esxupdate.log to see the progress.

updating-esxi-using-EHC-v4-5
If you have more than one or two hosts, I definitely recommend uploading the extracted offline bundle onto a webserver or a shared vSphere Datastore which you can the access from multiple ESXi hosts. This is a very nice way to easily upgrade your ESXi hosts without having to go into the ESXi Shell or enable SSH. Pretty neat feature if you ask me! There are many other new enhancements included in this release, be sure to give them a try and let us know if you have any feedback by leaving a comment on my blog or better yet, directly on the Fling site.
