Work update :)

Tuesday, May 22nd, 2018

Well, as stated in my last post, I am now working with VMware technologies exclusively for the next 9 months or so. Working on vSphere upgrades (team of 3 doing around 300 hosts), environment supporting 7000 VMs. Pretty much the largest deployment I have worked in. I am also somewhat involved ...

New adventure!

Monday, March 12th, 2018

I resigned from my current position today, to take on a new challenge: self-employment. So SUBnet192 will officially become "inc." this week if all goes well! I am taking on a new mandate as a VMware Integrator for a large transport company in Montreal. I expect to be posting a ...

Fixing stale content libraries in vCenter Appliance

Saturday, February 3rd, 2018

Last year we had to rebuild our vCenter (I commented about that in a previous post) using a backup/restore procedure provided by VMware. After the restore, the Update Manager was broken (it's now fixed) and the Content Libraries were also lost. I didn't have time to fix it until today. ...

Skype For Business – Can not update OnPremLineURI as the user has dirsynced onpremise LineURI

Sunday, September 24th, 2017

We had some legacy conference rooms that were renamed over the years, and as part of the infrastructure cleanup project we're doing, I changed several attributes in the AD account to clean that up (anything that had to do with email/sip address was changed). Resync'ed with AD Connect and all ...

Reconfigure Update Manager on VCSA

Monday, August 21st, 2017

We had an issue with our vCenter appliance 6.5 when we upgraded to 6.5u1, that required a full redeployment. We backed up the database and redeployed the appliance. We took that opportunity to rename the appliance, which we were told was the only way to do that (backup/redeploy/restore) by VMware ...

Rolling back a vSphere upgrade

Sunday, February 26th, 2017

Ahem... Being a vExpert doesn't mean you don't make stupid mistakes like everybody else... I pushed an update to vSphere 6.5 on a host and tada! Purple screen... I rebooted, crossing my fingers that it was a one time thing but no, it came back. Then it dawned on me to check ...

vExpert 2017

Wednesday, February 15th, 2017

I was awarded a "vExpert" for 2017 by VMware! What an honour! Never thought I'd qualify for it, but I guess my humble efforts are recognized. Thank you VMware!

Introduction to VMware Photon OS

Wednesday, February 8th, 2017

I wanted to play with Photon, so I was looking for some ideas/purposes to deploy a Photon VM in a Windows "shop" :) There's always some docker packages you can find that can be useful (SMTP server for test/dev environments for example). One good use I found is to build our ...

Stretched cluster VM localisation

Tuesday, November 29th, 2016

A colleague asked me to help him out with an issue he had. On a stretched cluster, some VMs had storage on Site A but were powered-on on site B and that's a no-no in a normal situation. There's no built-in mechanism other than using DRS groups to do so. ...

Another certification…

Friday, October 21st, 2016

I regularly post about the latest certification exams I took... And today was the first of two for Cisco's CCNA Datacenter certification. In my new role, I am doing a lot of Cisco UCS and a bit of Nexus configurations and since I had little to no exposure to these platforms, ...
