That was going to be my question too.

If it's Sun and you follow the NVRAM ID Replacement steps:


You should be able to have it come back up with the right HOSTID 
without a problem

IIRC there was a way to do that on SGI equipment as well.

Self protection: the means of protecting one's self. People expose the 
weaknesses which pain them, and thus form a group. Before they know it 
they begin to exclude those who are not one of them, but what becomes 
of those who have been excluded? I smiled at the children who lived in 
a tight group in their rickety house. Sure, let's live today, let's 
live tomorrow, and let's live the day after that, even if it means 
living in eternal pain. - Vash
