VMworld 2010, Day One Thoughts

August 31st, 2010 · VMworld

Day One

I’ve really been trying to go over the events of day one at VMworld 2010 and it’s been a lot of information to digest.  There’s certainly a lot of cool technology and I’m not really sure I understand any of it well enough to really speak authoritatively and I’m actually Ok with that for now.  The real take away for me on this first day has been the people I’ve met.  Hitting up a few different venue I’ve had the opportunity to meet far too many guys I’ve communicated with exclusively via Twitter or through reading blogs.  I don’t think there’s been a single person i wouldn’t love to sit down with, tip a pint and have a lengthy discussion with.  After the crew of tweeps I ended up with a crew from the vSpecialist team at EMC.  I need to say vie been following that team a fair amount since it’s inception and watching the talent being picked up.  These guys really. Are the best of the best in the virtualization, storage and networking disciplines.  Although i didn’t suspect I’d be meeting a bunch of elitist, pretentious guys I certainly wasn’t prepared for the team I met.  Every single one of the people I’ve met have been some of the most gracious, sincere individuals I’ve come across in a long time.

The solutions exchange was awesome but insanely crowded, couldn’t take it for very long.  Due to the crowds, I only attended one session and what I saw I loved.  Stepping into a session on View Performance and Best Practices we ended up being introduced to View Planner, a workload generator, profiler and reporting tool.  Awesome stuff to be seen and is available now, or will be with the GA availability of View 4.5.

Enough technology, day two should be bringing a lot more of that.

VMworld Prep Thoughts

August 12th, 2010 · VMworld

First, this is NOT a complaint. Understood?

Now; Wow, too many sessions to actually grok.  I printed out the entire session list, got a beer, spread list out on bar table and poured through everything that looked interesting.  At some point I made the decision I had to either commit to nothing but the Desktop track or exclude it completely.  I eventually chose the latter even though there is strong interest.  Desktop virtualization just seems as though it will be the easiest of the product line to gather more information on from my local VMware technical team due to VMware’s large push on the product line.

Even excluding the entire Desktop track I’ve managed to fill my schedule and have secondary sessions in case of a full room.  I still haven’t quite figured out what to give up so that I can squeeze in a few hands on labs.  What I’ve gotten from my local SE is that the Advanced Lab Tutorials are really going to be follow ups to the hands on lab sessions that will be going throughout the days.  I need to make the absolute best out of this, I want it all…I think I need to drop some of my expectations and accept that I’m going to miss out on some sessions, some social networking and maybe a bit more.

That said, I’m still more than just excited!  See you there.

vCenter does not support hosts of this type (VMware ESX 4.0.0)

July 28th, 2010 · VMware

First, let me say that I failed to troubleshoot this alone and ended up making call for assistance.

Environment: vCenter 4.0 U1 with ESX 4.0 U1, two locations.

I encountered an odd error that occurred when I had detached an ESX server from an existing cluster and attempted to add it back in.  The host had come down for hardware repairs, I removed it from the cluster so it wouldn’t show up on my vCheck reports.  Upon attempting to add the server back I received a pop-up from the vCenter client with the message “vCenter does not support hosts of this type (VMware ESX 4.0.0).”  I spent several hours, far too many maybe, troubleshooting this as a host issue but was not finding anything of interest in the logs.  I could see that the vpxuser account was being created, key exchanges occurring but then the vpxa scripts were never installed.  In frustration I rebuilt the ESX server with exactly the same outcome.  I found logging in the ESX server ‘Authd error: 551 There is no VMware process running for config file vmware-vpxa’.  This lead to VMware KB Article 1007337 which indicated that there was insufficient free space on the ESX server file system.  This was not my issue.

Next I pulled another ESX server out of the cluster and attempted to add back without the same result.  Adding these hosts to my other vCenter server was successful.

Finally on the right track I started troubleshooting my vCenter server and found the following relevant logging.

[2010-07-26 16:35:01.592 02728 error 'App'] [VpxdHostUpgrader] Unrecognized bundle version 15. The bundleversion.xml file may be out of date
[2010-07-26 16:35:01.592 02728 info 'App'] [VpxdHostUpgrader] vpxa not reporting correct version. bundleVersion = 15, build = 208111, expected bundleVersion = -1
[2010-07-26 16:35:01.715 02728 error 'App'] [VpxdHostUpgrader] Unrecognized bundle version 15. The bundleversion.xml file may be out of date
[2010-07-26 16:35:01.715 02728 info 'App'] [VpxdHostUpgrader] vpxa not reporting correct version. bundleVersion = 15, build = 208111, expected bundleVersion = -1
[2010-07-26 16:35:01.776 02728 info 'App'] [VpxLRO] — FINISH task-18739 — domain-c34 — vim.ClusterComputeResource.addHost — 07063040-6EC0-44DE-9F79-2E1652BFA653(371258EB-2C3F-49F2-ACB8-147A610F6F0A)
[2010-07-26 16:35:01.776 02728 info 'App'] [VpxLRO] — ERROR task-18739 — domain-c34 — vim.ClusterComputeResource.addHost: vim.fault.NotSupportedHost:
(vim.fault.NotSupportedHost) {
dynamicType = <unset>,
faultCause = (vmodl.MethodFault) null,
productName = “VMware ESX”,
productVersion = “4.0.0″,
msg = “”,
}

So the error is stating that vCenter cannot compare vpx bundle version but what turned out to really be the case is that vCenter could not find it’s own bundleversion.xml file.  In fact, the entire contents of ‘C:\Program Files (x86)\VMware\Infrastructure\VirtualCenter Server\upgrade’ was missing.

Quick fix, since I was fortunate enough to have another vCenter server, was to copy the contents of the directory to my problematic server.  At this point I was able to add the ESX servers into the cluster without incident.  In fact, all seems to be well now and I didn’t even have to restart services.  Now, the real question I need to be asking is “How did the contents of my directory go missing?”

I have asked VMware to review, clean up and publish an internal KB article that lead me to the ultimate solution.

Wrong Place, Wrong Time

April 14th, 2010 · Personal

Earlier I mentioned that I had changed jobs and this is one of those cases where it’s become obvious that the move was just the wrong place at the wrong time.  When I was working I absolutely loved the job, and how could I not when it’s all VMware all the time.  I somehow managed to score almost exclusive SRM jobs which made my life all the better.  Unfortunately there’s a lot more in a career change than just the work being performed.  Enough said, I hope.

There was an opening at a local company for a position in which I had written the job description that I decided to take after some discussion and an interesting offer.  Yep, I’m going back to the place I left taking on the same role as a virtualization and storage engineer.

I sort of feel like I’ve come home again, it’s a nice feeling.  I’m going to miss the opportunities presented in the role of a consultant and I’m sure I’ll be back at some other time in some other place.

First Impressions of Life as a Consultant

April 3rd, 2010 · Personal

I can say for sure that it’s not quite what I expected.  I’m not entirely sure what I did expect but I knew that I’d love the technology and the challenge ahead.  I was pretty sure my level of knowledge was not quite sufficient for the job but looked forward to the pressure to learn quickly.  The travel isn’t for me and I knew this going into the job.  I have accepted the travel and cannot complain.  I expected to be a billing machine, this is no surprise here and, again, I cannot complain.

What I didn’t quite realize, call it just being naive, was that some IT professionals don’t necessarily want to have a consultant in their shop.  My experiences and perception is the exact opposite, though I always was the one to make the decision as to whether to purchase PSO for an implementation project or not.  It’s no surprise that many of my peers don’t necessarily get to make that decision, I still find the response to my presence as a consultant surprising.  This is where one needs to have people skills and be able to form a bond with others quickly, I’ve found that taking them out for happy hour helps!

I do have some concerns with the methods in which I was dropped into my first jobs though will not go into it deeply for obvious, professional reasons.  I do have to say that it’s a damned good thing that all jobs to date have been on the one VMware technology that I’m extremely comfortable with, Site Recovery Manager.

The exposure to different environments is amazing, even better than I thought it would be.  The inability to get work done in an infrastructure that’s not mine kills me.  I can’t stand waiting on something like having a LUN provisioned, zoning all paths to storage instead of just one, making decisions on virtual networking, creating a portgroup, installing a patch, etc.  I haven’t yet worked in an environment where I could not either do or facilitate work.  My experiences are all SMB and I know that this is extremely different in some large shops, it not a surprise but still frustrating.

Mostly, I miss having that infrastructure that I can claim ownership of.  This I did not anticipate at all.  There is no vSphere/storage environment that I am responsible for, that I can assess and dream up changes to make it better, and nothing that someone else is holding me accountable for.  Might seem odd to some but I love having that which I can own and am expected to maintain for highest performance and reliability.

Sure, implementation projects are cool.  I still miss some of the day to day work that I’ve had in the past.  I am very sure that I only miss this because of my smaller environments and due to the fact that I could own my environment.  I had HBA to physical disk including any virtualization layer in between and more.  Now I have a project to plan and execute on.  Don’t misunderstand, I love the opportunity to architect a project just as much as the next IT professional, or I suspect we all like this part of it.  I just miss that which was mine and I’m not so sure what to do about that.

This does not mean that I don’t like my job, quite the opposite.
