copy root disk from IDE to scsi

[Khalid Schofield]

Hi,
random question. I've a sun system running obsd 4.2. I though I didn'  
have a scsi card with openfirmware so I installed on an IDE disk and  
spent ages configuring the system. It's a mail server also so I don't  
have the time to have a few hours of down time.

How would I go about cloning the 80Gb IDE disk which has only a few  
Gb's in use to my 73Gb scsi disk? Also what boot variables need to be  
set in openfirmware to get it to autoboot from the scsi disk?

thanks

Khalid
