You’d be surprised how many times I see datastore that’s just been un-presented from hosts rather than decommissioned correctly – in one notable case I saw a distributed switch crippled for a whole cluster because the datastore in question was being used to store the VDS configuration.
This is the process that I follow to ensure datastores are decommissioned without any issues – they need to comply with these requirements
- No virtual machine resides on the datastore
- The datastore is not part of a Datastore Cluster
- The datastore is not managed by storage DRS
- Storage I/O control is disabled for this datastore
- The datastore is not used for vSphere HA heartbeat
I started the TrainSignal VMware vSphere Optimize and Scale (VCAP5-DCA) Training course as part of my preparation for taking the exam which I took at the beginning of this week - I'm still waiting to hear the results. One thing I found when I started preparing is that there is an overwhelming volume of information - the Exam Blueprint is a great place to start as that lays out what will be tested. There are 9 sections and 27 objectives laid out, with knowledge, skills and abilities and tools required for each objective. The volume can be overwhelming, even if you already know most of it!
I found the VMware vSphere Optimize and Scale (VCAP5-DCA) course provided me with a framework on which to hang these topics - it covers pretty much every objective in the blueprint directly and allows you to get a picture of what you already know and are confident on and areas where you need to really focus on learning. Once I identified areas to study I used a number of really helpful resources as well as the VMware documentation to boost my knowledge on those topics. Quite often I re-watched the relevant topic in the TrainSignal course, but most important of all is getting into the lab.
VMware products have featured very high on my to-do list so far this year, with new hosting and DR solutions either completed or well underway. The simplicity, resilience and strength of vSphere never gets old!
I have also had the privilege to attend several London VMUG meetings all of which have been excellent! They have been superb opportunities to meet new people, put faces to Twitter names and learn more about current and forthcoming technologies orientated around visualization. If you have not had chance to get to one yet, do try, they are really worthwhile!
Also I was able to attend my very first #vBeers in Bath! (we really need to have another soon)
As a customer of VMware it's been interesting to see the launch of the Horizon suite (formally Project Octopus) of which Workspace is of great interest. It's solutions like this that really make sense to me especially with the arrival (like it or not) of BYOD. Other products such as View are also on my to-do list but one thing at a time!
As some of you know I was fortunate enough to win the recent V.I.T Competition so I shall be joining many others at VMworld in Barcelona in October. This will be a first for me and frankly I cannot wait! So expect me to be tweeting like a maniac with pictures of the event and me trying not to look too maniacally happy!
In recent weeks I have been wondering what is next for VMware concerning vSphere, I have heard very little save for rumors and speculation (vSphere 5.5 or 6.0? etc etc) traditionally they announce such things at VMworld so by the end of August we should have a better idea! I am sincerely hoping for significant improvements to the web client.. especially if they stick to their guns about retiring the .NET client.
I presently use VeeamOne and Veeam B&R both of which are incredible value for money. I recently sat in on a Veeam B&R v7 presentation (due out in August 2013) and wow.. these guys just keep making it better and I am convinced this is at least in part to their excellent attitude towards customer feedback either directly face-to-face or via their forums. Other vendors need to really take note, as from a customer point of view nothing gets your attention more than seeing your suggestions/queries taken seriously and responded to in a quick and timely fashion.
There is no question my two favorite words this year so far are VMware and Veeam. (some of my colleagues will testify to that with a distinct groan hah!)
Yesterday I attended my second ever #LonVMUG and did my first ever VMUG presentation! Generally it was a great day, with loads of really good sessions and some really cool community and vendor content.
As ever it was great day for socialising and networking with people who you interact with on twitter. For me one of the major benefits of the VMUG is learning from other people’s experience. Twitter was alive with the hastag #LonVMUG and it definitely adds something to the day to be active
The VM estate that I manage is large: there are more than 20 different clusters and over 300 hosts of varying ages and hardware levels – as a consequence there are various different versions of ESX and ESXi running. Upgrading the hosts is somewhat akin to painting the Forth Bridge, a never-ending task. So keeping the thousands of VMs at the correct hardware and VMtools versions can be a bit of a losing battle.
What if I want a report showing me all the VM names, Hardware Version, VMtools Status, Tools Version Status and Tools Version – how do I go about finding that?
