Netapp sdk LunInfo object returns null for volume

[tom_yuyitung]

I am able to connect to NetApp filer and get a list of LunInfo objects, but all LUN report null for volume. What am I missing? Here is code snippet:

LunListInfoRequest lunReq = new LunListInfoRequest();
LunListInfoResponse lunListInfoResp = runner.run(lunReq);
 for (LunInfo lun : lunListInfoResp.getLuns()) {
            System.out.println("------------------------------------------------");
            System.out.println("Serial Number       : " + lun.getSerialNumber());
            System.out.println("Device Text Id      : " + lun.getDeviceTextId());
            System.out.println("Device Id           : " + lun.getDeviceId());
            System.out.println("Volume              : " + lun.getVolume());
            System.out.println("Uuid                : " + lun.getUuid());
            System.out.println("State               : " + lun.getState());
            System.out.println("Path                : " + lun.getPath());
            System.out.println("Size                : " + lun.getSize());
            System.out.println("Used                : " + lun.getSizeUsed());
            System.out.println("------------------------------------------------");
        }

Result: LUNs:
Serial Number : XXXXXXXXXX
Device Text Id : null
Device Id : null
Volume : null
