All Things Virtual 24

 

Just a very quick All Things Virtual as I haven’t been able to read as many blogs as I had wanted due to work commitments and the studying for my VCAP-DCA taking up a large portion of my time.

 

First is the delay to the vExpert results. The results were said to be released on the 6th of May yet were delayed by two weeks and then last week the guys from the vSoup podcasts spoke to John Troyer at the Boston Gestalt IT Tech Field Day and he explained that due to a number of the VMware employees who were selected to give their opinions on the candidates still not having replied it has been delayed for another two weeks (John said two weeks last week Friday but I have a feeling it will need another week above that). It is a shame this has been delayed so much and is a let down for the people who give so much of their spare time to the VMware community, for VMware to then take an extra month and a half to give the results of the vExpert nominations. John did however promise they would be out before VMworld Smile

Talking of VMworld the Session catalogues for VMworld US and VMworld Europe have been posted. There’s a number of very exciting sessions happening and it’s great to personally see so many people I know form the London VMUG and via twitter whose sessions have made it after the public voting. If you’ve never heard of VMworld or have never been before I blogged about each of the days happenings when i went to my first one last year if you’re interested in getting any idea of what an average day at the conference is like All Things VMworld Day 1, Day 2 and Day 3.

The next London VMware User Group has been announced for the 14th of July. Unfortunately I will be away on holiday over this time but as I’ve stated many times in a number of blog postings on this blog the VMUG’s are an awesome day out and the amount you learn from the sessions and from fellow attendees is well worth your time. I was able to attend the last one on the 12th of May and wrote up a blog posting about the day if you want to get an idea of what happens during the day. If you are likely to be around the London area on the 14th of July I would highly recommend registering on the VMUG site and attending.

I’ve been trying to fill my slightly ADHD mind with all things VMware in preparation for my sitting of the VCAP-DCA exam and as mentioned in my VCAP-DCA and DCD Resources Page I’m a massive admirer of David Davis’s Trainsignal videos as they allow me to spend as long or short on each topic as I want and allow me to watch them via my iPad or laptop whenever i have a chance. David has recently released his VMware vSphere Performance Monitoring Training. I’ve only briskly looked at the video’s in the set as I’m trying to complete his VMware vSphere Troubleshooting Training set of videos first before starting the new ones but the videos look as amazing as ever and as sad as it is I’m actually excited to watch them. If you haven’t used David’s videos before I would HIGHLY recommend them especially if you are looking to do your VCP4 or your VCAP-DCA

Avamar Windows VMware Image backup fails with Generic 10013 error in Avamar administrator and "Unable to access file[Datastore location]" in vCentre

 

For the past day and a half I’ve been receiving the above error in my Avamar v5.0.3.29 server and in VMware vCentre every time I tried to backup certain virtual machines via the Windows VMware Image plugin. I searched all over the web and couldn’t find anything related to the problems I was experiencing and tried loads of different ideas and looked for similarities between the virtual machines that were failing but found nothing.

As is the case sometimes, once you ask for help you stumble across the solution on your own. As soon as I posted a discussion on the EMC Community Network about my problem and asked for some help/guidance on the problem and then found a posting on the ECN about a problem with the error code I was getting in Avamar Administrator (id 10013). The environment I’m running the backups in hasn’t been upgraded to version 4.1 yet so it did fit the criteria’s for the problem and fourth possible root cause and solution in the list was spot on and fixed the problem for me.

I was planning to write the exact steps I followed but while searching the internet I noticed one of the Varrow bloggers Hugh Griffin had beaten me to it and posted about the error and the same steps I followed(the second workaround).So due to my hating people who repeat my solutions to problems on their blogs with minimal credit I felt it was only fair to give him the credit so here is his blog posting of the solution “Avamar 5.0 VMware Image Backup Error” (Personally I have to put two dashes instead of one like Hugh did for it to work so it only works for me if i do –x22=8192)

Now for the upgrades to vCentre to make sure I don’t need to run the workaround  for much longer clip_image001

EMC Information Storage and Management(ISM) exam experience

 

Associate

For the past few weeks I have been learning and studying for the EMC Information Storage and Management(ISM) exam. I decided to set this goal for myself a few months back, as I felt that storage knowledge was lacking from my repertoire and due to it being a prerequisite for the EMC Cloud Architect certification I thought I should try obtaining it.

This morning I sat the exam and I’m very pleased to say I passed it clip_image001. The exam certainly tested me on some questions whereas on others it was quite simple and straight forward. The questions covered all the modules and technologies covered in the course/book fairly equally although there were a few things not covered in the book or course that I remember that was asked.

The resources I used for the exam were four things:

  1. The training course. Due to my working for EMC this allowed me to do the online training for the exam rather than attending the course. The online courses (I say courses as mine were split into four different modules whereas the training classes cover all four in the one course) were really good and allowed me to do it as and when I could, which is partly why it has taken me so much time to finally sit the exam after doing the online course. The course is really good and even though it does give you examples of EMC technologies/services which provide these capabilities (which some people may not like) it does give you a really good base knowledge if you’re a storage noob like me and the EMC examples are a small section of it all.
  2. The ISM Book. This in my opinion was the best resource for the exam as I read it cover to cover and used it extensively for writing notes and looking up different things. The course wasn’t enough for me personally and I’m pretty certain if I just did the online course I would have failed it. This may be due to my doing the online course rather than attending the instructor led one but I still think the book is a must read. Simon Long has done a quick write up on the book on his site if you want to know more about it and has attached a video review done by EMC vSpecialist Bas Raayman at EMC World 2009 on the book too clip_image001[1].
  3. The online practice exam. This helped me greatly with peace of mind in knowing I was prepared for the exam and was really helpful in showing me parts I needed to re-read and study more. You can take the exam as often as you like and if you get the questions wrong it will tell you where to look to learn more about the subject you got wrong.
  4. Research. Yes ok maybe a bit of a soft point but searching the internet and learning/researching more about different things I was unsure about really helped me understand some things much better (converting CHS to LBA) and helped me have more confidence in my answers in the exam. There were also a few people’s blog postings about their experiences of the exam and what they used to study that helped me greatly. The two main ones were
    1. Gina Minks’ blog posting on the exam was a really great resource and pointed me to the Proven Professional community where a large portion of the questions I had, had already been asked and answered.
    2. EMC vSpecialist Nick Weaver’s blog posting on his passing the exam was also helpful in my making sure there weren’t additional resources I needed to use before the exam.

For anyone looking to sit the exam, good luck it’s a good and fair exam. Next for me is my VCAP-DCA which unlike the gentleman writing the VCAP-DCA exam at the same testing centre as me, will require me to study more than a weekends worth of playing in my lab (he was a VMware instructor though)
