Get ESXI Host HBA WWN

-
From time to time I have to send HBA WWN and WWP reports to our Storage Team so they can make sure the right LUNs are mapped to the right hosts. That is can be a really easy task if you have a few servers as you can go into the configuration within the Web Interface for VCenter and get the information needed. If you are in a situation like I usually am though and you have multiple hosts usually in the hundreds to get that information could take quite a while but there are quick and easy PowerCLI commands that can help get that information fast and exported to CSV. This simple script can be used to get a report of WWNs for all hosts withing one VCenter site but can also be narrowed down by cluster or by single host.

A couple of weeks ago I was having a conversation about security hardening my ESXi hosts and how often passwords are changed and of course it's not as often as it should be. Most admins that deal with passwords know the best practice is to change your passwords at least every 90 days and I was looking for an easy way to do that on multiple hosts without having to touch each one. In my lab environment I currently use the same password for all of my hosts so my thought was to write a PowerCLI script that I could use to change the passwords on all the hosts and keep it the same password on all of them. I wrote the script to log into VCenter and get all of the host and then log into each host and reset the password. For me this was a simple way to be more secure even though the password is the same on all hosts. Here I created the script with the "Reset-HostPasswords" function. To execute that function I would then run the command. To make the command easier to us

Resetting Customization Spec Password after VCenter Upgrade

Following a recent upgrade from VCenter 6.5 to 6.7 I ran into an issue with Windows VM deployments using Customization Specifications. The deployments kept failing with the error "The VCenter Server is unable to decrypt passwords stored in the customization specification." After some research I found out the this occurs because the encryption keys are updated during the VCenter upgrade and the passwords in the Customization Specs can no longer be decrypted.  Solution ------------------------------------------------------------------------------------------------------------------------------------------------------------------- To resolve this issue I found out I would have to edit the Customization Spec and enter the passwords on the "Administrator Password" and "Workgroup or domain" tabs. Re-enter the local Administrator password in the Customization Spec. Re-enter the password for the Windows Domain account used to add servers to
