Change the root password in hosts and Host Profiles. For good security measures you should change the password of your root account on your ESX(i) servers on a regular basis. Instead of logging on to each and everyone of your ESX(I) servers, you can easily automate this process. But what about the new ESX(i) hosts you will roll out in between root password changes and where you use a Host Profile to configure these new ESX(i) hosts ? Will you need to run a script after the deployment to change the root password ?

Turns out that you can easily update  the root password in your Host Profile with the help of an SDK method. The installed hosts. There are numerous scripts available in the blogosphere to accomplish this. But for good measure, this is one script that can do the task. These ESX(i) hosts can excluded by adding their hostname to this array. Line 6- 8: The script needs to run in Multiple mode, in other words it needs connections to multiple v.

Sphere servers at the same time. For the run of this script I also disable the warning messages for deprecated properties, this to avoid a long list of warning messages. The script remembers the current settings before changing them. Line 1. 0: The script gets all the ESX(i) servers and excludes the ones we defined in the array in line 4.

Line 1. 1- 1. 4: The script makes a connection to the ESX(i) server and changes the password of the root account. Line 1. 2: If you want to track the ESX(i) hosts for which the script is changing the root password, you can set the $verbose. Preference variable to Continue instead of the default Silently. Continue. Line 1. The script restores the Power.

CLI Configuration settings. The Host Profile. When you use Host Profiles to configure your newly deployed ESX(i) servers, you will need to update the root account in those Host Profiles on a regular basis as well.

Profile  PS> Set- VMHost. Profile. Extended - Profile $prof - Admin. Password . Instead of reinventing the wheel, I used a function called Copy- Property function from Dennis Verwiej.

Line 3. 9- 4. 1: My simplistic Object By Name (OBN) implementation. Line 4. 5: The copy of the Config property to the Host. Profile. Complete. Config. Spec object. Line 4. 7- 5. 5: To the copied Host. Profile configuration the script adds the Admin.

Password. Policy definitions. Line 5. 7: The Host. Profile is updated with the Update.

Host. Profile method. Line 5. 9: To emulate the behaviour of the Set- VMHost. Profile cmdlet, the function places the updated VMHost.

Profile object on the pipeline. Sample usage. The function to update the Host Profile can be called with the Host Profile as a parameter.
