    Folks,

I had asked how to change the SCSI device number on a system disk because I
needed to move the disk from the internal to external bus on a DEC 3000/400.
All filesystems are AdvFS.

The quick and dirty solution:

# ./MAKEDEV rz8
# rm /etc/fdmns/root_domain/rz0a
# rm /etc/fdmns/usr_domain/rz0g
# rm /etc/fdmns/usr_domain/rz0h
# ln -s /etc/fdmns/root_domain /dev/rz8a rz8a
# ln -s /etc/fdmns/usr_domain /dev/rz8g rz8g
# ln -s /etc/fdmns/usr_domain /dev/rz8h rz8h
change /sbin/swapdefault (my swap is on another disk so I don't need this)
change boot device to DKB0


I got replies and owe thanks to:
