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.
