I purchased two 4.3 gig IBM External Scsi drives and want to use ccd to
make them mirrors of each other.  I would like to install from my 2.2.5
cds onto these drives.  Is there a way to set it up to install onto
mirrored drives at install time or can I do this later?

I want to be able to boot off of these ccd drives.


What does the following mean:

It appeared when I was trying to install 2.2.5 on my external IBM 4.3gig
Ultra SCSI.  I am using a 2940 ultra, and are properly active terminated
externally.  The adapter is set to use ultra mode(20mhz?) on this device
which is id0. This is the only device external, and the only device
period (3' cable).

sd0(ahc0:0:0): parity error during data-in phase
sd0(ahc0:0:0): ABORTED COMMAND
sd0(ahc0:0:0): Initiator Detected error message received, retries: 2

sometimes retries were 1-4

here is my dmesg:
