Problem matching vSphere Storage with HDS volume via WWN

I'm trying to match a vSpere datastore with the HDS volume via WWN.

 

In vSphere, I can see that the datastore has the following WWN:

 

Device: HITACHI Fibre Channel Disk (naa.60060e8013357e005020357e0000011d)

 

 

I'm using SMI-S REST API to retrieve the volume WWN from HDS:

 

instance of HITACHI_StorageVolume {

  BlockSize = 512;

  Caption = "285";

  ConsumableBlocks = 4294967296;

  ElementName = "00:01:1D";

  Name = "HITACHI R50342BE011D";

  NumberOfBlocks = 524611584;

  OperationalStatus = {2};

  OtherIdentifyingInfo = {"60060e803642be00000342be0000011d"};

  SystemName = "HUS VM.213694";

  Usage = 32768;

  CreationClassName = "HITACHI_StorageVolume";

  DeviceID = "HITACHI R50342BE011D";

  SystemCreationClassName = "HITACHI_StorageSystem";

};

 

If to compare these two WWNs, I can see that they are different:

 

VC:     60060e80 13357e005020357e00 00011d

HDS:  60060e80 3642be00000342be00 00011d

 

What could be the reason for that? What are the meaning for the digits after the HDS prefix?

 

Thank you,

Andrei
