Adding PowerShell Hosts with Kerberos Authentication: krb5.conf Explained

By |June 18th, 2015|Orchestrator, vCAC, Virtualization, vRA, vRO|0 Comments

When adding Powershell hosts to vRealize Orchestrator using Kerberos Authentication, one has to create the krb5.conf file. There are various articles on that and the best one I’ve seen is “this one”, so I am not going to repeat all that information here. 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. […]

Connection pool shut down (Workflow:Invoke a REST operation / REST call (item0)#6)
I checked the inventory and the target host was still there and nothing seemed out of […]

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 […]

Useful Links for NTP Configuration in vSphere Environments

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 […]

By |February 2nd, 2015|vCenter, Virtualization, VMware, vSphere|7 Comments

Chances are that unless you are an organisation new to vSphere or want an installation in the lab, you will be upgrading your existing vSphere infrastructure to the new vSphere 6.0 at some point in the future. As there are some design changes in this version, there are decision points that must be considered before […]

vSphere 6: VMware Certificate Authority (VMCA): Design Decisions

By |February 2nd, 2015|vCenter, Virtualization, VMware, vSphere|5 Comments

We all know the pains that vSphere Certificate management presents us with. While VMware’s Certificate Administration tool has made life a bit simpler, it is still quite a chore to generate requests, get the certificates (in the right format) and installing it in the right order. It was also quite a bit of work to […]
