How to download offline VSAN HCL file for VSAN Health Check Plugin?

05.16.2015 by William Lam // 4 Comments

One of the coolest features in the new VSAN Health Check Plugin is the automatic verification of your underlying hardware (hosts, disks, storage controller & drivers) by automatically checking it against VMware's VSAN HCL (Hardware Compatibility List).

The VSAN HCL database can either be downloaded automatically from VMware.com or manually uploaded if you do not have direct or proxy internet access. There was a question this morning on Twitter asking where the offline VSAN HCL file be downloaded from? I was actually curious as well and looking at Cormac Hogan's excellent VSAN Health Check documentation, I found the answer at the very end of the document 🙂

To download the offline VSAN HCL file which is actually is just a JSON file, you just need to load the above URL into a web browser and then save the file.

After you have downloaded the VSAN HCL file, you can either upload using the vSphere Web Client under the "Health" section of the VSAN Health Plugin or you using the following RVC command and specifying the path to the file:

vsan.health.hcl_update_db /localhost/ -l /root/all.json

As a bonus, I also had some fun parsing the VSAN HCL JSON file. Below is a graph that I was able to generate after extracting some useful information using the following script found here.

How to get notifications when a component on the VMware HCL changes?

11.05.2014 by William Lam // Leave a Comment

Last night, I received a pleasant and surprising email, you can see the details in the screenshot below:

This was a surprise because it was something I was tinkering around with back in March (8months ago!) to see if I could some how generate notifications when changes were being made to a specific component/device on the VMware HCL also known as the VCG (VMware Compatibility Guide). I suspect many of you have used the VMware HCL at least once if not many more times and as you can imagine, it would be nice to be able to get notifications or alerts when something has changed for a particular component or device that you might care about.

I was thinking about this problem because at the time I was interested in receiving updates on a particular VSAN disk controller. While browsing through the HCL, I had noticed there was an RSS feed icon located on the upper right hand corner for each component/device as shown in the screenshot below.

I thought maybe I could do something interesting with that? I decided to use one of my favorite SaaS services IFTTT (If This, Then That) which I have blogged about in the past on how to send SMS notifications using vCenter Server Alarms. I found an RSS to Email IFTTT recipe and created a notification based off of one of the Intel RAID Controllers by specifying the RSS feed URL.

I knew this was going to be a bit difficult to test given the HCL does not get updated that frequently and even if it does, I have to be monitoring the right device that received the update. I completely forgot about this recipe until yesterday when I had received the email stating an update had been made to this device. I guess it worked after all 😀 If there specific things you care about on the VMware HCL and you want to be able to receive notifications for any updates, you can create several IFTTT recipes that can either send you an email or notify you through some other method. I think this is a pretty nifty trick instead of continuously checking the VMware HCL every so often for changes, unless you are looking for brand new component/device that has not been added to the HCL.
