vRealize Automation: Troubleshooting Mail Configuration (or notification) Issues

By |August 31st, 2015|vCAC, Virtualization, vRA|0 Comments

On a couple of engagements in the recent past, I encountered situations where I was configuring Inbound/Outbound mail for newly-installed vRealize Automation environments.  Despite assurances from mail admins that settings provided to me by them were correct, I found that mail didn’t just work smoothly and I had to do some minor investigations. There isn’t […]

Workrave: Saving Lazy IT People from RSI (and other ailments)

By |July 7th, 2015|General, Strategy|0 Comments

I don’t know about you but I happen to be pretty lazy when it comes to taking breaks while working in front of a computer. This is especially true if I am working from home. There is always “let me finish this first and then I’ll take a break” which of course, never happens.

Knowing that […]

However, I thought to write something up about what’s important to remember while […]

Storage System not found on HP StoreVirtual VSA

By |May 29th, 2015|Virtual Lab, Virtualization|5 Comments

A quick one this: Yesterday, I had to shut down one of my Shuttles, running my HP StoreVirtual VSA (12.0.00.0725.0). Usually, it’s not a problem as there are three nodes in the cluster and it remained up as expected, after the shut down. However, when the node came back, the storage node didn’t come back automatically. […]

ProTip: Use “watch” to monitor or troubleshoot ESXi

By |April 29th, 2015|ESX, VMware, vSphere|2 Comments

Just thought I should do a quick post about a command that is extremely useful but often forgotten and that command is “watch”. Syntax of this command is:
watch PROG ARGS
where “n” is the interval in seconds (2 by default).

This command is used as a wrapper, to constantly update results from another command, at a […]

By |March 31st, 2015|ESX, vCenter, Virtualization, VMware, vSphere, Windows|0 Comments

A few months ago, I was helping out a customer with a time configuration issue on their vSphere environment. For one specific question, I investigated and wrote the post:

ESXi Time Configuration: Don’t point it towards the Windows Domain name

However, while doing the investigations, I went through various documents produced by VMware. As NTP (Network Time […]

Time for a book review. This book was released in November last year so I know it’s a bit late but I’ve just got my hands on it. I hope you won’t mind.

It is written by Mike Greer and is just over 300 pages long, divided into 13 chapters. It starts with a brief introduction […]

CrowdChat on vSphere 6

By |February 6th, 2015|Virtualization, vSphere|0 Comments

A few days back, Corey Romero asked me if I am interested in co-hosting a CrowdChat session on vSphere. Having never been on CrowdChat, jumping from nothing to co-hosting seemed a bit intimidating but I’ve always liked a challenge so I said yes. Plus, this was another something that I could do for this amazing community easily […]
