如何使用 netapp ontap api (8.1) 和 java 获取存储系统的磁盘、聚合和 LUN 信息

Question

我想使用 netapp ontap api 8.1 获取有关磁盘、聚合和 LUN 的信息。我能够使用以下代码获取卷列表：

VolumeListInfoIterStartRequest volumeListReq = new VolumeListInfoIterStartRequest();
    Iterator<VolumeInfo> volumeIter = apirunner.iterate(volumeListReq,10);
    VolumeInfo volume ;
   while(volumeIter.hasNext()) {
         System.out.println("------------------------------------------------");
         volume = volumeIter.next();
         System.out.println("Name               : " + volume.getName()); 
         System.out.println("Type               : " + volume.getType()); 
         System.out.println("State              : " + volume.getState());
         System.out.println("Total size (bytes) : " + volume.getSizeTotal());
         System.out.println("Used size (bytes)  : " + volume.getSizeUsed());
         System.out.println("Total disk count is .. "+ volume.getDiskCount());
         System.out.println("sysinfo is .. "+ volume.getSis());
         System.out.println("Total available size .. " + volume.getSizeAvailable());
         System.out.println("UUID is .. "+volume.getUuid());
         String vol = volume.getName();
         System.out.println("snapshot is "+ volume);
         System.out.println("------------------------------------------------");
     }

但是当我尝试将 api 用于与上述完全相同的 LUN 时，我在迭代函数中出现错误。我的代码是：

LunListInfoRequest lunreq = new LunListInfoRequest();
     System.out.println("luninfo is .. " + lunreq);
     Iterator<LunInfo> lunInfoIter = apirunner.iterate(lunreq,10);

我在最后一行出错。

如何获取有关磁盘、聚合和 LUN 的信息？
