Table 1‑15. Bindings of the Initializing Scriptable Task Element (Continued)
Parameter Name Binding Type
Bind to Existing
or Create
Parameter? Binding Values
vmCounter
OUT Create
n
Local parameter: vmCounter
n
Source parameter:
vmCounter[attribute]
n
Type: number
n
Description:
The counter of the virtual
machines inside the array
vm
OUT Create
n
Local parameter: vm
n
Source parameter:
vm[attribute]
n
Type: VC:VirtualMachine
n
Description:
The current virtual machine
having a snapshot taken
snapshotVmArray
OUT Create
n
Local parameter:
snapshotVmArray
n
Source parameter:
snapshotVmArray[attribute]
n
Type:
Array/VC:VirtualMachine
n
Description:
The Array of virtual
machines of which snapshots
have been taken
The Initialize scriptable task element performs the following scripted function.
//Retrieve an array of virtual machines contained in the specified Resource Pool
allVMs = resourcePool.vm;
//Initialize the size of the Array and the first VM to snapshot
if (allVMs!=null && allVMs.length!=0) {
numberOfVms = allVMs.length;
vm = allVMs[0];
} else {
numberOfVms = 0;
}
//Initialize the VM counter
vmCounter = 0;
//Initializing the array of VM snapshots
snapshotVmArray = new Array();
VMs to Process? Decision Element
The VMs to Process? decision element determines whether any virtual machines of which to take snapshots
exist in the resource pool. The following table shows the bindings that the VMs to Process? decision element
requires.
