The node contains a SAN Volume Controller product serial number that is written to the system board hardware. The product serial number is also printed on the serial number label which is located on the front panel.
This number is used for warranty and service entitlement checking and is included in the data sent with error reports. It is essential that this number is not changed during the life of the product. If the system board is replaced, you must follow the system board replacement instructions carefully and rewrite the serial number on the system board.
