hardware.systemInfo.serialNumber Returning None

[arjunprakashn]

Describe the bug

Get ESXi host object

esxi_obj = content.searchIndex.FindByDnsName(dnsName=esxi_host, vmSearch=False)
if esxi_obj is None:
print(f'ESXi host {esxi_host} not found.')
si.Disconnect()
exit()

Retrieve hardware info from ESXi host

print(dir(esxi_obj.hardware.systemInfo))
hardware_info = esxi_obj.hardware.systemInfo
product_name = hardware_info.model
serial_number = hardware_info.serialNumber

print(f'Product name: {product_name}')
print(f'Serial number: {serial_number}')

Here product name coming properly but serial number coming empty
Product name: XXX System x32 M6 -[1111AC1]-
Serial number: None

Reproduction steps

1.from pyVim.connect import SmartConnect, Disconnect
from pyVmomi import vim

Connect to vCenter or ESXi host

si = SmartConnect(host='your_host', user='your_username', pwd='your_password')

Get the host system object

content = si.RetrieveContent()
host_view = content.viewManager.CreateContainerView(content.rootFolder, [vim.HostSystem], True)
hosts = host_view.view
host = hosts[0] # assuming there is only one ESXi host in the inventory

Get the hardware system info

hardware = host.hardware
system_info = hardware.systemInfo
serial_number = system_info.serialNumber

Disconnect from vCenter or ESXi host

Disconnect(si)

print(f'The serial number of ESXi host {host.name} is {serial_number}.')

Expected behavior

serial number should get proper value but getting None

Hello,

I have a same issue, but not for all ESXI.
Can you give news for this bug ?
