Rewriting the SAN Volume Controller serial number using the CLI
The SAN Volume Controller serial number is normally rewritten by using the directed maintenance procedures, but can be rewritten by using the command-line interface (CLI).
To rewrite the serial number using the CLI, issue the following command:
svctask writesernum -sernum nodeserialnumber nodename
where nodeserialnumber is the serial number of your node and nodename is the name of your node. The serial number is written to the SAN Volume Controller system board. Immediately following this action, the system performs an automatic reboot.
