W2K3 Recovery using EMC Legato Networker

A few months ago I had a customer who was having some problems doing a full system restore of a Windows 2003 Server with EMC Legato Networker 7.2.1 –  The EMC Legato Networker folks told the customer that a full system restore was not supported and the Legato Networker was only able to backup and restore files not applications (I know this sounds ridiculous – but it is true).  Over and over EMC support continually stated that Legato only supported  Bare Metal Recovery (BMR) by using the ASR (Automated System Restore) capability inherent in W2K3.  The irony in all of this is that the customer was not attempting a BMR.  The customer merely wanted to do a full restore to a W2K3 host.  While the customer was out of luck due to the fact that EMC Legato would not provide support and they were uncomfortable with an unsupported configuration I took it upon myself to test this scenario.  I have been meaning to do this test and document it for a while but my time is limited.  Thank goodness for holidays and vacation time πŸ™‚

I ran the same test 5 times with the same results. IT WORKED EVERYTIME… I am not sure what the problem is here – maybe just communication.  I would be interested in feedback from anyone having problems doing this or anyone who has done this successfully in production.  Also if you have had similar issues with EMC Legato support I would be interested hearing about them.

As Nature Made Him: The Boy Who Was Raised as A Girl

0060192119.01

Late last night or early this morning I started cleaning out the closet in my office, when I came across a book that I read a couple of years ago as required reading for course cluster in female studies. I have read some bizarre books but by “As Nature Made Him: The Boy Who Was Raised as A Girl” has to be one of the oddest and strangely intriguing stories I have ever read. Thus I felt the need to introduce you to this story.

Check out this link for a summary of this brilliantly researched and written bizarre tale of medical tragedy, misguided advice, gender disforia and a renewed belief in the human spirit.

Microsoft antitrust litigation

Microsoft is the target of another antitrust litigation, this time in an Iowa court.  This story has an interesting twist, read about it here.

Plaintiff’s Exhibit 7264 gave me a good little chuckle. Almost three years ago, on January 7, 2004, Jim Allchin, the senior executive at Microsoft, sent an E-mail to Microsoft’s top two executives, Bill Gates and Steve Ballmer, and the subject was losing our way.

Mr. Allchin says, I’m not sure how the company lost sight of what matters to our customers, both business and home, the most, but in my view we lost our way. I think our teams lost sight of what bug-free means, what resilience means, what full scenarios mean, what security means, what performance means, how important current applications are, and really understanding what the most important problems our customers face are. I see lots of random features and some great vision, but that does not translate into great products. He goes on to say, I would buy a Mac today if I was not working at Microsoft.

I am sure Apple will capitalize on this – as well they should.  I only hope they do it in such a way that it is reminiscent of the 1984 Orwellian Macintosh commercial that Apple aired during the superbowl.  In my opinion the best commercial of all time.  I vote for this commercial to be a parody, Steve Carell would make a good Bill Gates πŸ™‚

Reflecting on my inner nerd

Technology has become the modern day version of the ’57 Chevy – at least that is what I keep telling my wife. People are crawling out of the woodwork as self proclaimed technologist – It’s been a long road of abuse to nerdom and I think that far to many people are catching an episode of StarTek 2.0 on G4TV (BTW – if you have not seen StarTrek Cribs on YouTube you have to check it out) and laying stake to the techie guru throne. As I articulated this week to a colleague the road to nerdom is paved with 8th grade wedgies and significant weight loss in the 9th and 10th grade. But that got me thinking, was the cream puff ’57 Chevy the real winner in late 50s or was it the brush painted sleeper that disillusioned the crowd – that’s what the 9th and 10th grade nerds have become, that brush painted nova that cleaned the clock of cherry street rod. The key to the kingdom is learning how to stay true to your inner geek while polishing the external geek. This is one of the first weeks that I have not traveled in the past two months so I have been spending some time knocking some projects off the list, one of those project is a Virtual Appliance – While building the appliance – I do my best work between 8 PM and 3PM a true nerd quality, I realized that I really am a nerd. The proof is in the pictures so lets get started:

Pictures of the Mindstorm robot that guards the door to my home office:

As if it is not enough that I still play with Legos – BTW these are not normal legos the big box in the middle is an onboard computer – of course I have to spend countless hours writing perl and java code to make my robot do cool stuff like follow my dog around the house – My daughter thinks it is the funniest thing. If you think legos are for kids google “lego mindstorm rcx” or check out this site http://graphics.stanford.edu/~kekoa/rcx/.

Next I found some pictures that I sent to colleagues when my daughter was born – she is 6 days old in these pictures.

It’s never to early to start educating πŸ™‚

Lastly I have amassed a ridiculous amount of compute power in my house. I think the total number of systems stands at approx 15 not including a few laptops – 1 quad proc and 3 dual proc systems. Virtual machines in the 20+ realm with most major open systems Operating Systems up and running from Windows XP, 2K, 2K3, Linux (Debian and RedHat based distros – my favorites are Ubuntu on the desktop and CentOS on the server), FreeBSD, HP-UX, Solaris and others.

I have to keep the window open in my office in the winter to keep the temperature regulated and in the summer I have a portable air conditioner that runs 24×7. You can see the AC unit in the third picture just to the left of the window – 10K BTU unit does a nice job, this year I put a drain line through the floor and into the basement sink so I do not have to empty the water every day, that was a real pain.

Lots of other equipment including RAID arrays, a Cisco IOS switch, FC Switches, a SCSI bus analyzer, and a SCSI-to-FC bridge to name a few.

It’s tough work staying atop the nerd mountain but it sure is fun, and it keeps the house warm in the winter. I also like having enough compute power to do almost anything I need to at home – It’s a huge advantage when you can work a week straight without sleep or a shower πŸ™‚

Happy Trails

Last Wednesday, December 13th 2006 the world said goodbye to 76 year old Al Shugart, the father of the modern disk drive. Al Shugart founded Seagate Technology and without his contributions many of use would not have 10 thousand songs attached to our hip.

Watch a speech given by Al Shugart entitled Half a Century of Disk Drives and Philosophy: From IBM to Seagate.

“It is important to remember when starting and growing a new company that cash is more important than your mother.” – Al Shugart

Homebrew wireless antenna

This was a howto that I used to have on my website, it has to be at least 4 or 5 years old but I was doing some filesystem cleanup this weekend and I thought that I would post it.

The purpose of this post was to share my 802.11b homebrew wireless antenna parts list and experience. Today I have a Linksys WRT54G roamabout cardrunning the Sveasoft Talisman firmware but when I originally wrote this I was using a Linksys WAP11 access point. For a wireless card I use a Cabletron pcmcia wireless card.

The card that you use is very important important, internal wireless cards in my experience (if anyone know different please let me know) do not offer the ability to attach an external antenna. I recommend a card that uses the Prism/Prism2 chipset.

My research initially started with commercial antenna that were approx $120 to $150 for a 5dbi antenna (remember this was a few years ago and prices have come down). I then stumbled across the 802.11b Home Brew Wireless Shootout page. Since I originally wrote this I have upgraded to amplifier indoor nf 150a commercial antenna, the thing is sick and if you never want to loose your signal I highly recommend it :). There are two important components, the antenna (in this case an omni-directional) and the amplifier.

For my homebrew antenna I choose the Flickenger coffee can waveguide design.

The hardest part of making the antenna was finding the proper parts. I have itemized the list of parts needed here:

(1) Coffe Can (36 oz, does not need to be a Yuban coffee can) – In my case it was a Maxwell House can – this happens to be what my parents drink. – $0

images

These parts I ordered from www.hyperlinktech.com. I would have included the direct links but they seem to change as the catalog changes.

(1) N-Female Panel Mount 4-Hole? 1 in. Flange Crimp Connector for Cable Types: RG58/141/142? Hyperlink CA195RW? WBC195? LMR195? Belden 8240/8219 – $32.90

anf-4000

(1) RP-TNC Plug to N-Male, 195-Series Cable – $20 (This allows connection of the antenna directly to the WAP device)

ca-rtpnma010

(1) ORiNOCO? AP-600/700/4000 Compatible to N-Male, 195R-Series Cable – $15 (The is for connecting the antenna directly to your pcmcia wireless card – great for war driving)

ca-amnma002

For additional instructions see Rob Flickenger’s web page on building the coffee can antenna. Happy homebrewing.
Good luck, I am in the process of doing some benchmarking on my coffee cantenna using netstumbler (http://www.netstumbler.com/). I should have the results posted after the holidays.

IPOs abound

The storage technology market is definitely heating up.  Bankers are pushing IPOs and startups are capitalizing on valuations that are reminiscent of the dot.com era.

CommVault (CVLT) who priced their IPO at $14.50 a share raised 161 million and closed the trading day Friday at $19.65 a share.
Riverbed’s (RVBD) IPO was priced at $9.75 a share and they raised $86 million, Riverbed closed the day Friday trading at $29.79.

This week it was Isilon (ISLN) and Double-Take (DBTK).  Isilon priced their 8,350,000 shares $13 per share and closed the trading day on Friday at $23.10 per share.  Double-Take priced their IPO at $11 a share and closed the Friday at $12.66 a share.

Who’s next?  Companies like 3PAR, BlueArc, Compellent, EqualLogic, LeftHand Networks, Mellanox and Onaro are on deck.  To put this in perspective before the CommVault and Riverbed IPOs the last storage company to go public was Xryratex (XRTX) over two years ago.  It’s obvious that the market is hot and thirsting for aggressive, nimble technology companies. 

The days of consolidation where storage giants like EMC, NetApp, HDS, IBM, etc… gobble up smaller players with great technology are slowing and valuations are on the rise.  I think the post dot.bomb apprehension may have finally begun to fade away.

The Compelling Event

After writing a couple of recent blogs I started thinking about opportunity creation.  I awoke this morning at 4:15 AM with the thought that successful opportunity creation lies in the ability to create a compelling event.  The best sales people I have worked with have an incredible and uncanny ability to create these events.  I believe that while customers are excited by strategy and vision ultimately purchasing patterns are tactical in nature.  Broad compelling events are often created created by industry requirements such as regulatory compliance requirements (i.e. – Sarbanes-Oxley, 17a-4, HIPAA, etc..).  Technology innovators typically create compelling events in the form of game changing technology (i.e. – data de-duplication, content addressable storage, continuous data protections, etc…) these technologies typically address a broader industry compelling event and they aim to provide a unique technological solution to a broader problem.  Lastly individuals have the ability to create a compelling events, orchestration and articulation of a solution that encompasses the problem, the technological solutions and the business process and benefit.

This idea popped into my head after reading through a one of my previous blog posts in which I spoke about VMware and partition offsets.  I was prompted following a link back to the original blog from the VMTN (VMware Technology Network) and comments such such as the following on the VMTN:

“Umm… let’s just say you need to do a better job educating. No idea what any of this means, and I’ve installed dozens of ESX farms.”

“…nobody has kept track of real geometries on drives for 10 or 15 years”

These are frightening comments.  Think of all the ESX users experiencing sub-optimal performance based on the fact that I believe this represents the rule rather than the exception.

Hence this got me to thinking about the term “Trusted Advisor” once again.  It is obvious that “Trusted Advisors” across the world are chasing the ubiquitous technology opportunities such as Microsoft, Cisco IP networking, etc… To me these advisors are analogous to the doctor you goto when you need some penicillin – you know your sick, you just can’t write the script so you goto a doctor and pay the $5 co-pay for a broad spectrum antibiotic.  At one point the diagnosis and treatment of influenza was a specialty but this train has left the station.  These advisors deal in volume and while they may harbor discrete expertise unfortunately not only are the problems ubiquitous but the solution and the expert knowledge is as well.  On the other hand there is the doctor who sees 10 patients a year who deals in a specialized field that seems to be outside the grasp of the masses, he is expensive but worth the money to those who capable of affording him or her.  BTW – Nothing precludes the specialist from playing in the volume business if he or she so chooses, it begs the question of why they don’t?

With this all said, value is measured by ones ability to comprehend and quickly cross-reference symptomatic  information with expert knowledge in an area where others are incapable of comprehending the complexity.  If anyone watches the TV show “House“, this is the advisor I am describing.  Back to my example of VMware and partition offsets, VMware two years ago was perceived as a fairly complex, the certification pass rates were far lower than they are today.  VMware made a conscious effort to remove the need for command line expertise realizing that most users were coming from the Windows world and that pervasive adoption would require simplicity, today 99% of the operational management of VMware happens from the Virtual Center console.  Most users are unaware or just don’t care that the CLI is far more efficient, simplicity has become a primary feature.  It is no wonder that most users disregard aligning partition offsets, after all this would require the command line.

Tragic demise of an Open Source pioneer…

I have been meaning to blog on this for weeks but just never got around to it. Today I had a call and that reminded me. On October 10th Hans Reiser was taken into custody by Oakland, CA authorities on suspicion of murdering his wife. Hans Reiser is the developer of the popular Linux file system ReiserFS. Based on this Novell SuSE Linux have announced that they will move away from ReiserFS to the ext3 file system. Novell claims that the move to ext3 is prompted by stability issues associated with Reiser4 and that ext3 will soon match the performance of ReiserFS. One has to wonder if the fact that Hans Reiser is on trial for the murder of his wife played a part in this decision – If convicted Hans may have nothing to do but work on the code, does anyone know what the computers are like in the California penal system? πŸ™‚ More interesting to me and a little know or unadvertised fact is that the EMC Centera (great EMC Centera internals presentation) product leverages the ReiserFS, a move away from ReiserFS may not be as easy for EMC. For those of you who need validation of Centera’s use of the ReiserFS maybe this thread will help. EMC aquired the Cetera technology from Brussels, Belgium based FilePool NV in April 2001, the acquisition was reported as cash deal valued at less than 50 million dollars (aka – a home run!).

The Hans Reiser pre-trial commenced this Monday, Hans has entered a plea of not guilty. ReiserFS developent is obviously stalled for the time being.
