Find the Service tag or Serial number of VMware ESX host

There might be a few reasons that you would need to do this. But if you need to locate the Serial Number of server or Service Tag of your Dell server you can do this from the service console command line. In the past I have needed this to schedule service and also to confirm the identity of a server for the Vendor that was on site. In case you do not have a database to reference or maybe someone mistyped the digits you can always fall back to this method.
Type the following command from the command line on the service console and you will get some Vendor details and serial number information.

[root@host name]# /usr/sbin/dmidecode |grep -A4 “System Information”
