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. Table 2-19 shows the bindings that the VMs to Process? decision element requires.
