Hello, I just installed a second disk in a machine, and while I was at it I thought I'd setup a redundant root partition on it and make it bootable so I can have a backup if the primary disk becomes unbootable. The primary disk is IDE (wd0), while the new disk is SCSI (sd0). I have created a small partition on sd0a and copied /kernel, /stand, /bin, /etc, /tmp and /sbin into it. (I can mount the partitions on sd0 without problems.) I can boot by manually typing 1:sd(0,a)kernel from the `boot:' prompt, but the machine seems to stop at the line `changing root device to sd0' (it gets through the device detection and such up to that point). I haven't built a special kernel for the second disk or anything, and was wondering if maybe the line `config kernel root on wd0a' in my kernel config might be causing a problem? Anyways, I guess I was wondering what `officially' I have to do to setup a second boot/root disk on a machine (what directories need to be copied, what kernel options need to be set?). Thanks in advance for your help, please email me directly. --dave David K.
