Not sure where this discount is coming from but I figured I would share it with you. You can pick up the vSphere 4.1 HA and DRS Tech Deepdive for $ 17.96 on Amazon.com. That is about as cheap as it can ever get in my opinion. Pick it up.
By the way, Frank and I are working on a major Update of the book. If you spotted any glitches or have any comments drop ’em here so we can incorporate them. Before you ask, yes we will be reconsidering an ebook version!
I blogged about this almost two months ago and just on Luc’s blog that the release date has been set and the cover art was released. I wanted to remind all of you the book that is one of a kind, VMware vSphere PowerCLI Reference: Automating vSphere.
Release date: 28th of March
Authors: Luc Dekens, Alan Renouf, Glen Sizemore, Arnim van Lieshout, Jonathan Medd
ISB: 0470890797
I’ve had this question too many times over the last couple of weeks and instead of answering all of them separately I figured I would dedicate a blog article to it so that I can reference to that. Here we go:
Q) Will the e-book version of the HA/DRS deepdive be available soon?
A) No. We have decided that we will not release an e-book (including pdf, ibook, kindle) version of the book. It required a full reformatting of the book which is simple not feasible at this point in time. As it is a “self published” book we are responsible for not only the content but also the formatting etc. Sorry about that, for “Volume 2” however we will reconsider this.
I hope this answers your question(s). Thanks and again our apologies, the only option is the paper version.

Want a free HA/DRS Technical Deepdive Book? Watch vChat 15!
In Episode 15 of our vChat series, we have a couple of special guests with us whom I’m sure you would have heard of or if not met before, Frank Denneman and Duncan Epping. These guys embody almost all things deep-dive when it comes to vSphere and with the recent release of their new book VMware HA/DRS Deepdive and we take the opportunity to ask about the background behind the book, whether an electronic version is in the pipeline along with their plans for any future publications. We discuss VMware Partner Exchange (PEX) 2011. Other topics, as you’d imagine, cover the VMware iPad app (and the potential security issues) and their home vSphere labs.
I received a very valid question this week from someone who bought our book. The question was as follows:
On Page 35 it is mentioned that a Secondary Node is not automatically elected as a Primary if a Primary fails. It then goes on to state the conditions under which this does occur, one of these is if the primary node becomes disconnected from the Cluster. When an ESX host fails doesn’t it always end up in the “disconnected” status, if so why isn’t the role transferred?
This one had me thinking for a couple of minutes as it was 6 months ago that I wrote that section, but I knew I tested this back then. When a host fails it will not receive the status “disconnected” but it will receive the status “not responding”. You can disconnect a host by right clicking it and selected “disconnect from cluster”, that would transfer the role to another node… in the case of “not responding” this doesn’t happen as vCenter is unaware of what happened to the host.
