[Release] ESXi-Customizer-PS version 2.0

I just released a new major version of my ESXi-Customizer-PS PowerCLI script that greatly simplifies and automates the process of creating fully patched and customized ESXi 5.x installation ISOs using the ImageBuilder snapin.What's new: A new operational mode (-update) allows to update a locally existing ESXi Offline bundle with the latest patch level from the VMware Online depot. This way you can easily bring a vendor supplied ESXi installation ISO (like the HP Customized ISO) to the most recent ESXi patch level. ... [Lire la suite]

Hyper-V 2012 R2 Best Practices

Travaillant sur un projet de déploiement de Windows 2012 R2 avec Hyper-V, et avec les différentes contraintes de fonctionnement de Hyper-V, j'ai cherché chez Microsoft un guide recensant les "best practices" ou bonnes pratiques. J'ai trouvé celui-ci qui détaille assez bien les différents points à prendre en compte : http://blogs.technet.com/b/askpfeplat/archive/2013/03/10/windows-server-2012-hyper-v-best-practices-in-easy-checklist-form.aspx Avec une petite pépite, car Hyper-V étant basé sur Windows, il faut patcher, et Windows...

Bulk Registering Virtual Machines with PowerShell

I recently rebuilt a Hyper-V server – where all of my virtual machines were shutdown first and stored on a secondary disk.  Once I had finished installing the operating system and had Hyper-V up and running – I wondered what the most efficient way to get the virtual machines all reconnected would be.  I ended up using PowerShell to do a bulk import; however this did involve a bit of experimentation to get right. The first thing I had to deal with was the fact that our “import-VM” command requires that you provide a .XML... [Lire la suite]

Garder un historique des logs cluster

Quand il arrive un incident sur un cluster, la majeure partie des informations nécessaires à l’explication se trouve dans les cluster logs. Cependant, il est fréquent que la période intéressante ne soit pas couverte par le cluster log. Pour pallier à ce désagrément, il est possible de créer une tâche programmée qui génèrera les cluster logs tous les jours, couvrant les dernières 24 heures. De cette manière, si un incident arrive vous aurez toujours à votre disposition un historique de plusieurs semaines, voire de plusieurs mois en... [Lire la suite]

vCheck for Exchange 2010

One of the main areas I redesigned in vCheck 6 was the new plugin concept, in my mind this was a nice HTML output which could be used for more than just vSphere checks, the plugins could potentially be any product which has a PowerShell snap-in or module, and even some which don’t Shortly after the release I was contacted by Phil Randal who had done just this, he has taken the vCheck framework and written some Exchange 2010 plugins, this now turns the vCheck report into an Exchange monitoring report too. Awesome stuff! Now you can... [Lire la suite]

VM Start-up script

ack in Jan 2010 I wrote a script which shut down the virtual infrastructure, this was used to ensure your VMs were shut down and then your hosts were shut down in an orderly manner, ideal for things like UPS shutdown scripts etc. A slight spin on that is a Start-Up script, I was asked by a couple of people if I had one of these, it also becomes more relevant with the vCenter Virtual appliance, no need for HA and DRS rules or to manually search for the vCenter Virtual Appliance if there is a power outage. The script below will... [Lire la suite]
