HP Master ASE: HP0-Y37

I have just passed the HP exam “HP0-Y37: Migrating and Troubleshooting Networks.” This means I I have now passed all required exams for “HP Master ASE - Network Infrastructure 2011.” This is a run-through of my impressions of the exam, and what I used to study for it.

VMware EVC Mode

Recently I’ve been doing more VMware work. It’s been a while, but it makes a nice change. At this site, we have 100+ hosts, and thousands of VMs. Recently we were making some changes to the physical networking of some of the hosts, and we needed to evacuate all VMs from a host. But when we went to migrate the VMs, we got this warning:

IMC - test script for Cleanup_Parser

When developing IMC adapters, sometimes you have problems with parsing the output correctly. Adapters that use the CLI to retrieve a backup will have extra lines that creep in, such as the show run command. You may also have some lines you wish to strip out - e.g. you might want to remove the ntp clock-period line from Cisco devices, as it triggers false positives indicating a configuration has changed, when it really hasn’t.

IMC - Device Adapters for Mikrotik and Netscaler

I’ve written basic versions of Device Adapters for IMC, to allow configuration backup of Miktrotik RouterOS-based systems, and Citrix Netscaler-based systems. I’ve also posted a modified Juniper adapter, with a couple of modifications so it now works with SRX-110 devices.

Asking Questions on Forums the Right Way

I’ve spent a lot of time on technical and non-technical forums over the last 10+ years. I’ve written thousands of posts on places like CPUG, CPshared, Thorntree, Packetpushers, NetOps, HP Support Forums, IEOC, etc. I’ve never received any financial gain for it, not even so much as a free T-shirt. No jobs, no promotions, nothing. But I believe that participation in technical forums is an important part of developing your career - you learn something technically, and maybe you’ll learn a bit about people along the way. I’ve also learnt a few things about the “right” way to participate in forums. I think I can sum them up as:

Website Survey Popups - Please Make it Stop

Years ago, I was working at a large bank. It was a large site, with a lot of employees, so there was a staff member working full-time in the mail room. Occasionally I would receive a delivery of replacement parts. I’d get a phone call letting me know there was a package to pick up, so off I’d go to retrieve my parcel. Sometimes it would get brought up to me, depending on what it was.

You Are Being Watched

A few weeks ago, I commented on Twitter that I was thinking about migrating from one product to a newly released product. It’s the sort of thing you do all the time, right? You wonder aloud: “Ooh, new product X looks interesting - I wonder if it would solve my problems better than product Y?” No big deal.

Apple's Mac App Store - Change Needed

When Apple launched the Mac App Store, I was quite interested in how it would work out. The App Store for iOS has been hugely successful, even if it is at times somewhat frustrating for developers. I’m also undecided on the censorship aspects - I should be able to have a wobbly boob app if I want - but I was prepared to give it a chance.

Speaking at HP Discover 2013

HP Discover is HP’s showcase technology conference, bringing together speakers, presentations, partners and products from right across HP’s product line. It covers everything from laptops to servers and software. It’s held twice a year, in Las Vegas in June, and in Europe in late November/early December. If you work with HP products or services in any form, it’s a great place to find out more about what’s happening, what’s coming up, and how to make the most out of your systems.
