This is not only about SAS expanders, but also cage info is in eprom on backplane. This is only possible by hackign 3PAR os and editing firmware database. Hack 7000 series was simple, just remove boot drive and connect to some linux box, change root pass and you are in. On 8000 series, boot drive has SED, so it is not so simple..
I wouldn't hack an array that was under an active support contract... but if your planning to decommission and old array, take it off support and throw it in a lab, call support and get the root passwords changed to something you are in control of.
