Description

The goal for this script is to schedule a task for a lot of Virtual Machine. You have to list all of your virtual machines that you want to affect by this schedule in a csv file. The name of the task is define in the script as well as the description. The CSV file must be have a column’s name “Name”. The task created is configure for Once time, it’s not do for periodic time. You can’t configure it for periodic time with this script but you can modify it on line “VMware.Vim.OnceTaskScheduler”.
Please look at VMware SDK to perform this task.

Example :

Name
VM Name 1
VM Name 2
...

Requirements

Some options are mandatory to be able to schedule any task.

The first option is “Task”. You can use three parameters for this option (RebootGuest, ShutdownGuest or PowerOnVM).

The second is “ScheduleTask”. You have to format this option like this “mm/dd/yy HH:mm”.

The third is “EmailNotification”. This one is not mandatory but you can add it if you would like to receive an email when the task is done.

Example

PS > ScheduleTask -PathFile C:\PathToMyCSVFile.csv -ScheduleTask "01/25/20 20:31" -Task ShutdownGuest -EmailNotification xxx@xxx.com
