HI Mat,
In one my case, I am getting more than one service tag in Hardware.SystemInfo.OtherIdentifyingInfo. It is a Nutanix box. Nutanix server setup has multiple chassis and each one contains multiple server nodes (VMs) . So for Nutanix when we check a VM Information we get 2 serial numbers: 1) node serial that corresponds to a VM Or server Node 2) Block Serial that correspond to a chassis
It seems that VSphere API is reporting both serial numbers in Hardware.SystemInfo.OtherIdentifyingInfo. From observation, it seems that Node serial number is reported first and Chassis serial number is reported later in Hardware.SystemInfo.OtherIdentifyingInfo . But I am not sure that reporting order (Node serail reported first and chassis serial later) will always remain same. If yes then we can take the first service tag as the serial number.
Do you think what I have observed will always hold true and can i take the first service tag value as the serial number in case more than one service tags are found?
