Initialize this with the size of "luns"

I'd move this logic to the LUNs class:
public boolean isDummy() {
return getLUN_id().startsWith(BusinessEntitiesDefinitions.DUMMY_LUN_ID_PREFIX);
}
Line 37: continue;

The get here is redundant.
Worse case scenario - you'd run a DELETE statement that removes nothing.
It's still faster than SELECT+DELETE.
