Last week my boss came to me and asked if I could write a script for a customer to register VM’s after being replicated from once VI environment to another. I agreed to take on the project and go for it.
Like everything I do these days I decided to use powershell to write the script. I have taken a liking to it and the fact that I can run the scripts on both ESX and ESXi hosts saves me from having to re-create scripts all the time. So I plugged away to 3am wrote the script, tested it inside out and sideways in my lab. I was confident in the scripts ability to register all vm’s form all datastores I went ahead and sent it off to the customer.

A whitpaper was posted in the VMTN communities Thursday outlining the differences between the ESX 3.x and ESX 4.x service console. It further offers resources for transitioning COS based apps and scripts to ESXi via the vSphere Management Assistant and the vSphere CLI. Also mentioned briefly was the vSphere PowerCLI. If you are a developer or write scripts for VMware environments, also check out the Communities Developer section.
I hear it time and time again…The full ESX console is going away. ESXi is the way to go. I know there are valid arguments for keeping ESX around, but they are few. Failing USB keys may be a valid argument, but I have not heard of this happening. If that is the case, use boot from SAN. You need SAN anyway. As for hung VM processes, there are a few ways to address this in ESXi.

Tuesday April 21st VMware announced they will be releasing vSphere 4 by the end of 2nd quarter. This is exciting news for many looking to take advantage of some of the new features available with this release. In this post I’m going to walk through a handful of some of these new features. There are over 100 new features in vSphere 4 and this post doesn’t come close to covering them all but I will be touching on some really exciting ones with more to come in my next few posts.
Let’s start with the new home screen. It’s a handy way to navigate all the configuration areas of vSphere.

This simple little useful script can be used to add a new nfs datastore to all the hosts in an esx cluster. Alternatively you can modify this and replace get-cluster CLUSTER_NAME with get-datacenter DATACENTER_NAME and add an ISO nfs share to your whole datacenter.
foreach ($ESXhost in get-cluster CLUSTER_NAME| get-vmhost)
{
New-datastore –nfs –vmhost $ESXhost –name [datastore_name] –path [/remote_path] –nfshost [nfs_server]
}

This simple little usefull script can be used to create a portgroup at the cluster level. This enables you to create it once and have it be consistently deployed to all the ESX and/or ESXi hosts in your cluster.
foreach ($ESXhost in get-cluster CLUSTER_NAME| get-vmhost)
