IBM SVC payload difference for same call in different node

[Biswajit Mukherjee]

Hi,

I have a 2 node IBM SVC storage array. I am trying to discover all hosts name using SMIS class and  WBEMClient like below

public static CIMInstance getHostname(WBEMClient client, String arrayID, CIMInstance host) throws WBEMException

{

String hostObjectPath = namespace + ":IBMTSSVC_ProtocolController.CreationClassName=\"IBMTSSVC_ProtocolController\",DeviceID=\""+arrayID+":"+host.getProperty(SVCApiConstants.SVC_STOR_HDWR_PROP_HOSTID).getValue().toString()+ "\",SystemCreationClassName=\""+SVCApiConstants.SVC_CLASSES_IBMTSDS_STORAGESYSTEM+"\",SystemName=\""+arrayID+":"+arrayID+"\"";

CIMInstance spcHostInstance = null;

try {

spcHostInstance = client.getInstance(new CIMObjectPath(hostObjectPath), false, true, null);

} catch (WBEMException e) {

logger.logError("Could not fetch the host info for the host "+host,e);

throw e;

}

return spcHostInstance;

}

for one node I get payload as 

[instance of IBMTSSVC_ProtocolController {

  AccessGranted = true;

  ClientType = 0;

  ConnectionRole = {2};

  CreationClassName = "IBMTSSVC_ProtocolController";

  Description = "Logical controller used for modeling the authorization path from host ports to volumes.";

  DeviceID = "0000020320018336:1";

  ElementName = "ESXi6.5_HOST_173";

  EnabledDefault = 2;

  EnabledState = 5;

  HostClusterId = "";

  HostClusterName = "";

  MaxUnitsControlled = 1;

  Name = "ESXi6.5_HOST_173";

  NameFormat = 0;

  OperationalStatus = {0};

  RequestedState = 5;

  SiteId = "";

  SiteName = "";

  StatusDescriptions = {"Unknown"};

  SystemCreationClassName = "IBMTSSVC_Cluster";

  SystemName = "0000020320018336:0000020320418336";

  TransitioningToState = 12;

};]

for the other node , payload is different 

instance of IBMTSSVC_ProtocolController {

  AccessGranted = true;

  ConnectionRole = {2};

  CreationClassName = "IBMTSSVC_ProtocolController";

  Description = "Logical controller used for modeling the authorization path from host ports to volumes.";

  DeviceID = "0000020320418336:0";

  EnabledDefault = 2;

  EnabledState = 5;

  MaxUnitsControlled = 1;

  NameFormat = 0;

  OperationalStatus = {0};

  RequestedState = 5;

  StatusDescriptions = {"Unknown"};

  SystemCreationClassName = "IBMTSSVC_Cluster";

  SystemName = "0000020320418336:0000020320418336";

  TransitioningToState = 12;

};

So, ElementName ,Name   are missing in 2nd payload. 

Any Idea, what could be problem here?
