get backing scsi LUN for datastore?

[jarushepic]

I've been digging through the various classes available from HostSystem.queryHostConnectionInfo() and none of the properties seem to contain the naa id that I see when I look at LUNs on an HBA.  How does one get at the backing LUN for a datastore?

I can find the actual SCSI LUNs, but can't seem to figure out how to associate them with datastores.

VcHostSystem.config = VcHostConfigInfo

VcHostConfigInfo.storageDevice = VcHostStorageDeviceInfo

VcHostStorageDeviceInfo.scsiLun = VcHostScsiLun[]

VcHostScsiLun.deviceName = "vmfs/device/disks/naa.###########"

Figured it out.  For anyone else that wants to know:

I created two actions, one to return a hash of naa id => datastore object and another action to return a hash of naa id => scsi disk

// actions
//getDatastoresKeyedByLUN
var o_diskHash = new Properties();


for each (var scsiDisk in u_host.config.storageDevice.scsiLun)
{
  //System.log("-> LUN: " + scsiDisk.canonicalName);
  for each (var dataStore in u_host.datastore)
  {
  if (dataStore.info.hasOwnProperty("extent"))
  {
  for each (var scsiDiskPartition in dataStore.info.vmfs.extent)
  {
  if (scsiDiskPartition.diskName == scsiDisk.canonicalName)
  {
  o_diskHash.put(scsiDisk.canonicalName, dataStore);
  }
  }
  }
  }
}


return o_diskHash;


// getScsiDisksKeyedByLUN
var o_diskHash = new Properties();


for each (var scsiDisk in u_host.config.storageDevice.scsiLun)
{
  o_diskHash.put(scsiDisk.canonicalName, scsiDisk);
}


return o_diskHash;




// in workflow
for each (var can in dstoreMap.keys)
{
  System.log(dstoreMap.get(can).name + "(" + lunMap.get(can).canonicalName + ")");














}
