The problem, as I put it was

>and sd is not loaded for that device, so it isn't placed in /dev/rdsk.
>I haven't been able to figure out how to change the label so that I can

Thanks to Brett Lymn (blymn@awadi.com.AU) for pointing out that bad labels
are normal for drives that have not been partitioned. The drive was not
placed in /dev/rdsk when I rebooted because I was not using the "boot -r"
command at the OpenBoot prompt. The -r flag causes the /dev tree to be
reconfigured. Once this is done, running format will allow you to write a
good label.
