Use Storage vMotion to Properly Rename a Virtual Machine’s Datastore

I’ve been a VMware administrator for a while now, but a co-worked recently showed me this handy trick.  This assumes that you can do a Storage vMotion, This requires you to have the right version of vSphere, like Enterprise or Enterprise Plus. (Well, not exactly…  As Joe points out below, if you turn the machine off or suspend it first, you can do this with Standard as well.)

In vCenter, you can easily rename a virtual machine.  You just right click on the machine and pick “Rename”.  Every virtual machine consists of a folder and files in a datastore.  Unfortunately, right click, Rename does not change the actual names of any of the files or folders.  So if you use rename every now and then, and you have lots of virtual machines, you can easily get into a situation where there are lots of datastores with lots of virtual machine files and folders that don’t match the name of any known machine.  Confusing!  Read more to see the fix… Read more

Advanced Machine Room Cooling Systems at Cal Poly, SLO

We have an older machine room that has been through many years of equipment changes.  As a result, it doesn’t have *ahem* optimal cooling systems.  Some of our more active systems have been having cooling issues recently, and here’s what we did about it.  Maybe Santa will buy us real HVAC someday.  (On a more serious note, Cal Poly’s budget is in really bad shape.  What we get from Sacramento is not sufficient.  So when time are tough, you sometimes have to resort to cardboard and duct tape.)  Read on to see the gory details….

NetApp Certified Data Management Administrator (NCDA) – Passed NS0-154 Data ONTAP 8.0 7-Mode Administrator Today

I passed the new style (single exam) NS0-154  NetApp Certified Data Management Administrator (NCDA) test today.  I had the good fortune to take some instructor led courses for this from Fastlane – Data ONTAP 8.0 7-Mode Administration (DOT87M) and Accelerated NCDA Boot Camp Data ONTAP 8.0 7-Mode (ANCDABC87).  They were good preparation.  The exam was 75 questions, 90 minutes.  I passed it with a 99% (missed one) and it took me maybe 20 minutes.

1-800-Flowers? No, thanks.

1800_flowers_no_thanks1-800-Flowers and other online services like FTD and teleflora are at best a waste of money.  All they do is take your order, skim a fee off the top, and call a local florist to place the order.  The local florist loses the fee.

1-800-Flowers silently cancelled my Mother’s Day order.  They didn’t bother to tell me.  On their web site, when I logged in and checked my order, it said something like “Due to high order volume, no status is available.”   Later, the status changed to cancelled, with no explanation.  They never sent an email or text to let me know there was a problem.  I contacted customer service, and basically got blown off.  You can read the chat log below.

Like a lot of people have said things like, “In our final analysis, we think the best value for your money– with the least frustration- is to call a local florist and order your flowers directly.”  Yeah, I second that.  Better for you, better for the florist.

Test Centers near San Luis Obispo

computer_testIf you live in San Luis Obispo, CA area, there are no local Prometric or Pearson Vue test centers.  Cuesta College used to run one, but there was some sort of political hoopla over it and they decided to close it.  Your choices now are all like 100+ miles away.

Here’s my thoughts on the test centers I’ve actually been to.  I think that most (all?) of these do both Prometric and Pearson Vue.  I like Vue.  I like their registration process and using their website better.  Prometric’s website is clunky and often hangs and freezes in the middle of enrollment which always makes me wonder “Did that go through?  Should I click submit again?”

CompTIA Security+ – Passed JK0-015 CompTIA Security+ (2008 Edition) today

Security+_CE

I passed CompTIA Security+ today.  This is not a difficult exam, and if you have some computer security experience, it isn’t too challenging.  The reason I took this, and maybe why you should as well, is that it is one of the required certifications for Federal Information Assurance employees, as recently required by DoDD 8570.  Who knows, maybe you’ll be a Federal employee (or contractor) someday…

Support your local VMUG!

vmware-logoVMware sponsors local VMware User Groups worldwide.   I recently attended a meeting of the Santa Barbara VMware Users Group and had a great time!  The topic was VMware View, their flagship desktop virtualization solution.  VMware sent one of their Systems Engineers to do a step by step hands on demonstration of installing VMware View.  After a (free!) pizza lunch, Wyse demonstrated using their thin clients with View.  The coolest Wyse thin clients I saw were the ones made by Teradici that did native PC over IP (PCoIP) in hardware, like the Wyse P20.

Having installed both VMware View, as well as Citrix XenDesktop, I can honestly say both products have their relative strengths and weaknesses but that View has a far easier install process.
