I’m fairly new to SRM, but even so this one seemed like a real head-scratcher! If you happen to be using CA signed certificates on your “protected site” vCenter and “recovery site” vCenter servers, when you come to linking the two SRM sites you encounter SSLHandShake errors – basically SRM assumes you want to use certificates for authentication because you’re using signed certificates. If you use the default self-signed certificates, SRM will default to using password authentication (see SRM Authentication).
This had me scratching my head, what seemed to be a common problem wasn’t fixed by the common solution. It was actually my fault – too familiar with the product and setting things up too quickly to test. I installed a VCSA 5.5 instance in my lab as a secondary site for some testing and during the process found I couldn’t log on to the web client – it failed with the error:
So this morning I took the VMware Infrastructure as a Service exam (VCPVCD510) to gain the VCP5-Cloud qualification. The IaaS exam is available for existing VCP5-DCV holders to take without any other pre-requisites. I am very pleased to say I finished the exam in good time and scored 466/500 – the pass mark is 300. The Exam The exam itself is 85 multiple choice questions, and gives you 90 minutes to do them.
As a proof of concept I recently tried to virtualize OS X (Mountain Lion) - It is important to note that VMware is now licensed to do so and you can read more here. The following is an overview of the steps I followed to achieve my goal in some cases it was trial an error as I am not a regular Mac user. The Hardware As OS X requires Apple hardware to run you will have to find yourself a Mac that will install and run ESXi.
According to VMware, Infrastructure Navigator is …a component of the VMware vCenter Operations Management Suite. It automatically discovers application services, visualizes relationships and maps dependencies of applications on virtualized compute, storage and network resources. Effectively it takes a look at the network connections that are running between your VMs (and physical servers) and works out which applications and services are running on each, and the dependencies – both upstream and downstream – for each VM.
There are different schools of thought as to whether you should have SSH enabled on your hosts. VMware recommend it is disabled. With SSH disabled there is no possibility of attack, so that’s the “most secure” option. Of course in the real world there’s a balance between “most secure” and “usability” (e.g. the most secure host is powered off and physically isolated from the network, but you can’t run any workloads ).
Today was always going to be a bit of a funny day as I scheduled the VCAP5-DCD exam for 10am this morning. I am happy to say that I passed! I’m a bit light on VMworld to report today, so forgive my DCD experience to pad it out! Preparation I have to confess my prep for this exam was light – I literally only watched the TrainSignal course by Scott Lowe (@scott_lowe) and just about finished that last night in the hotel!
John Troyer (@jtroyer) asked a question on Twitter last night about a CloudCred prize of $1000-2000: @jtroyer a nice lab setup! — Sam McGeown (@sammcgeown) September 19, 2013 @jtroyer I guess a couple of hosts, storage and a switch, wouldn't get HCL certified for that but I'm sure it's doable! — Sam McGeown (@sammcgeown) September 19, 2013 That got me thinking – was it possible to create an entire 2 host lab with storage on a $2000 budget?
After my previous post about studying and the exam experience of the VCAP5-DCA exam (and 3 weeks of waking up to check my phone for the email all night) I am pleased to say that I received my Exam Score last week and it was a pass! I was really pleased to see that I passed with a very decent margin too, which was great! The rushed nature of the exam and long wait for the results leaves you going over the exam in your head convincing yourself how badly you’ve done, so it came as a huge relief and surprise.
With the release of vCenter Log Insight Public Beta (http://communities.vmware.com/community/vmtn/vcenter/vcenter-log-insight) I thought I’d strike while the iron is hot and run through the installation and configuration. Deploying the OVF This is such a bread and butter task that it doesn’t require more than a few words – it’s definitely worth looking at the Sizing PDF before you deploy (VMware-vCenter-Log-Insight-1.0-Beta-Virtual-Appliance-Sizing.pdf) as it’s not small even for a test installation. If you’re using less than the recommended 8GB RAM there are additional steps to change the heap size for performance.
