METHOD FOR MANAGING MAC ADDRESS FOR OPEN NETWORK ADAPTOR
First Claim
1. A MAC address management method for use in a computer system having a disk device to store a MAC address, and assigns the MAC address to an open network adaptor (ONA) printed board which has a memory retaining a MAC address and an open network adaptor when the ONA printed board is mounted into the computer system, the method comprising:
- reading the MAC address from the memory on the ONA printed board and storing the MAC address in the disk device and invalidating the MAC address stored in the memory, when an ONA printed board is mounted into the computer system for the first time; and
validating the MAC address stored in the memory of the ONA printed board mounted in the computer system, when a migration instruction is inputted.

4. A MAC address management method, in a first computer system and a second computer system each having a disk device to store a MAC address and assigns the MAC address to an open network adaptor (ONA) printed board, which has a memory retaining a MAC address and an open network adaptor, mounted thereinto, by which a first computer system executes:
-
reading, when an ONA printed board is mounted for the first time, the MAC address from the memory on the ONA printed board and storing the MAC address in the disk device and invalidating the MAC address stored in the memory; and validating, if a migration instruction is inputted, the MAC address stored in the memory on the ONA printed board, and a second computer system executes; reading, when an ONA printed board is mounted, the MAC address from the memory on the ONA printed board and storing the MAC address in the disk device. - View Dependent Claims (5, 6)
