Upgrade vSphere 4.0U2 ESXi to 4.1 ESXi

How to upgrade your ESXi 4.0U2 to ESXi 4.1. Contrary to what some may believe. VMware's documentation is not the simplest to navigate sometimes. However, this is what happens when you have technical writers typing up stuff for Systems Engineers! We don't need 10 pages of text to say the following!

You need vSphere CLI - Download Here vCLI
For Windows or Linux and install on your workstation.
Download the Upgrade Package for 4.0 to 4.1 or the Upgrade Package from 3.5 to 4.1
Power off your VM's and put the host into maintenance mode from the vSphere CLI prompt:

vihostupdate.pl --server hostname or IP -i -b c:\temp\upgrade-from-ESXi4.0-to-4.1.0-0.0.260247-release.zip -B ESXi410-GA

vihostupdate.pl --server hostname or IP -i -b c:\temp\upgrade-from-ESXi4.0-to-4.1.0-0.0.260247-release.zip -B ESXi410-GA-esxupdate

VMware vCLI Reference: http://www.vmware.com/support/developer/vcli/vcli41/doc/reference/index.html

Just FYI for new CLI folks on Windows. Make sure you cd into the /bin directory under the vSphere CLI so that you can run the Perl commands or just create an alias in Powershell.

Post installation. You will get a pop-up Window.

The required client support files need to be retrieved from the server 'vsphereclient.vmware.com' and installed. Click Run the Installer or Save the Installer.

I would recommend just running it if you have time.It is just going to update your vClient on your Windows/Linux machine.

How to Configure HP ILO 4 for Active Directory Login

1. Make sure that your Windows Active Directory Domain Controller has an SSL Certificate to support port 636 (HP's authentication doesn't like 389)

2. Use Softerra LDAP Administrator (or whatever is your preferred tool to get the OU path) if you don't know how to do it by heart (which...um...sometimes its better to verify).

3. Make sure that you have a way to authenticate users by adding in the OU where your restricted accounts are located. You don't want anyone in the domain to be able to login to the server.

ILO Login > Administration > User Administration - Click New and Add the Group DN Only:



Click Add Group and then you will see your group added. (*Make sure it's a security group)


4. Add in your Windows Active Directory DC to authenticate against (Verified against 2008R2):

ILO Login > Administration > Security - Directory (*Make sure it's the OU where the security group is)


5. Sign Out (Log off) and then Log Back in (If you don't see Direct…

How to Launch Citrix .ica files Using Google Chrome

Updated: 10/19/2013

One of the problems you may face when launching a Citrix Application in Google Chrome is that .ica may not launch automatically. This is what you have to do to make it work. (Tested only on Citrix XenApp 6.0/6.5)

1. Click on the tool option and select options (Windows/MAC - Settings)


2. Settings => Show Advanced…
