12 Add the following scripting in the bottom of the Scripting tab.
The following code returns an array of disk modes for the disks of the virtual machine.
var devicesArray = vm.config.hardware.device;
var retArray = new Array();
if (devicesArray!=null && devicesArray.length!=0) {
for (i in devicesArray) {
if (devicesArray[i] instanceof VcVirtualDisk) {
retArray.push(devicesArray[i].backing.diskMode);
}
}
}
return retArray;
13 Click Save and Close to exit the Actions palette.
You have defined the custom action the Take a Snapshot of All Virtual Machines in a Resource Pool workflow
requires.
What to do next
Create the workflow's schema.
Create the Schema of the Complex Workflow Example
You can create a workflow's schema in the workflow editor. The workflow schema contains the elements that
the workflow runs, and determines the logical flow of the workflow.
Prerequisites
Complete the following tasks.
n
“Create the Complex Workflow Example,” on page 97.
n
“Create a Custom Action for the Complex Workflow Example,” on page 98.
n
Open the workflow for editing in the workflow editor.
Procedure
1 Click the Schema tab in the workflow editor.
2 Add the following schema elements to the workflow schema.
