Hello,

Can any one tell me now to restore root to a different
disk. Here is the problem, we have an 8200 that came
w/digital Unix on an RZ24 (Dkd0). We would like to put
root on our swxcr disk, re0. We were trying to avoid
reloading the software from scratch. What I have done
so far is:

        Modified this line in the config file:

    config vmunix root on re0 swap on re0

        rebuilt Kernel (moved Kernel to re0)

        newfs /dev/re0a
        mount /dev/re0a /mnt
        vdump rz24a vrestore to /mnt
        edited /mnt/fstab to mount /dev/re0a /
                also added swap
        and rebooted re0a

I receive this error:

        panic: vfs_mountroot: cannot mount root
        sync the disks

        DUMP: problem w/specified dumpdev 0xa00001, status 19, not used
        DUMP: no primary swap, not ecplicit dumpdev.
                nowhere to put header giving up.

Any suggestions would be appreciated.

thanks in advance,
