A little mistake, the change is on AIX. Execute the command:
chdev -l 'scsi0' -a id='6' '-P'
on your SCSI board to change default ID from 7 to 6. Look for correct SCSI
name (here scsi0). Look also the option -P to do changes on database only,
cos this will require a reboot to take efect, specially if you got only one
SCSI controller or can't offline the controller.
