The Create Snapshot? custom decision element custom decision element performs the following scripted
function.
//A snapshot cannot be taken if one of its disks is in independent mode
// (independent-persistent or independent-nonpersistent)
var containsIndependentDisks = false;
if (vmDisksModes!=null && vmDisksModes.length>0) {
for (i in vmDisksModes) {
if (vmDisksModes[i].charAt(0)=="i") {

}
}
} else {
//if no disk found no need to try to snapshot the VM
System.warn("Won't snapshot '"+vm.name+"', no disks found");
return false;
}
if (containsIndependentDisks) {
System.warn("Won't snapshot '"+vm.name+"', independent disk(s) found");
return false;
