vCenter shows two serial numbers for each Nutanix ESX host. The first being the chassis serial number and the second being the serial number for the ESX host.
ADDM vCenter queries return the first serial number.
I believe customers of ADDM would benefit from ADDM discovering the Nutanix ESX host's serial number rather that the chassis that the ESX hosts resides.
