Re: Fixed (hardisk) device names?

does anyone know how to fix the device name on a debian linux
system? For example. If i have two IDE hardisks, the devices will
be named like this.


If i now must remove the first harddisk (/dev/hda) the second (/dev/hdb)
will be renamed to (/dev/hda) after the reboot. As i want /dev/hdb to be
a mirror of /dev/hda and used as failover disk _without_ opening the
case and tampering with the IDE bus setup, i want linux to keep the name
/dev/hdb for the drive no matter what happens.

Is this possible?

Another question. How can i copy two identical discs _including_ the boot
block? "dd if=/dev/hda of=/dev/hdb" doesnt do it and there are no raw
devices on linux AFAIK.



I would suggest making hdb in this case Secondary master. That will mean it is always hdc no matter what happens. Some bios' don't like trying to boot from slave HDD's. Otherwise look at setting up a RAID mirror as has been suggested already
