so if you don't have clustered vcenter but multiple esx machines or
|
||||
just diff clusters you can have a inventory per each and automatically
|
||||
group hosts based on file name or specify a group in the ini.
|
||||
|
||||
You can also use <SCRIPT_NAME>_HOST|USER|PASSWORD environment variables
|
||||
to override the ini.
