Whilst attemping to install the Dell ESXi Agent and upgrade the ESXi revision on a new VMware host, I hit the following issue.
Dell Agent - Error encountered: Description - I/O Error (17) on file /var/tmp: [Errno 17] File exists: '/var/tmp' Message - Unable to create, write or read a file as expected.I/O Error (17) on file /var/tmp: [Errno 17] File exists: '/var/tmp'
ESXi upgrade with Update Manager - The host returns esxupdate error codes: 10.
Using VMware Update Manager to upgrade ESXi from 4.0 to 4.1 is a pretty straightforward process, but what about if you need to complete other tasks as part of the upgrade.
For instance, if you are running Dell Hardware then the ESXi agent also needs to be upgraded from version 6.2 supplied for ESXi 4.0 to 6.4 supplied for ESXi 4.1. You may also see some changes in advanced parameters between the two ESXi versions that you need to amend after the upgrade - I blogged about some of these before.

I was lucky enough to be invited onto the vSoup virtualisation podcast to talk about the PowerCLI book. Details of what we talked about and how to win a copy of the PowerCLI book are below:

In this episode we’re honored to have Jonathan Medd as our guest! As Jonathan runs his own podcast called Get-Scripting PowerShell, he proves that not only is he a great host on his own, but a very good guest as well.
To upgrade Active Directory from Windows Server 2003 to Windows Server 2008 R2 requires the usual AD schema upgrade first of all. Windows Server 2008 R2 is 64-bit only, so if you try running the usual command to upgrade the schema from a 32-bit Domain Controller:
adprep /forestprep
you get the following result, “adprep.exe is valid, but if for a machine type other than the current machine.”:
An alternative is to try running it from a 64-bit machine that is not a DC, but then you discover that this process absolutely must be run from a DC:
Most projects have to start somewhere as an idea, and this one was no different. When Sybex contacted us, our idea suddenly became a reality and now after quite a journey, our book has finally arrived. Because most of the content of this book is inspired by the PowerCLI community, we decided to give something back. To celebrate the release of our book, we’re organizing a book raffle. Read the instructions below and enter the draw for a chance to win a free copy of “VMware vSphere PowerCLI Reference: Automating vSphere Administration”.
Whilst attending the recent MVP summit I was fortunate enough to get some podcast recording time with Travis Jones from the PowerShell product team. We are able to have a chat about the upcoming PowerShell Deep Dive Conference and the kind of treats instore for those lucky enough to attend. There’s still time to register for the conference so I highly recommend you do if you have the chance to attend.
A new feature in PowerShell V2 is modules. In this article for Simple-Talk I give you an introduction to PowerShell modules and how you might use them.

When I was first starting out with PowerShell one of the best ways I found for learning was to get real tasks to solve. One practical example of this I used at the time was the Scripting Games, a yearly event where you are set real world IT problems to solve with scripts. This year’s Scripting Games will be starting on April 4th and if you are just starting out with PowerShell then they are a great way to set yourself some challenges.
