To obtain service tag information for products that are currently registered with the Auto Registration feature, go to https://inventory.sun.com/inventory/data.jsp.
To access service tag information for your registered products, you must first log in with either your My Oracle Support account credentials or your Sun Online account credentials.
Be aware that the inventory web site provides information about discovery and registration methods that are not associated with the new Auto Registration feature. These other registration methods are used on a voluntary basis and registration is not mandatory. If you have installed Oracle Solaris 10 9/10, Auto Registration occurs upon the first reboot after an installation or upgrade.
