You need to create a vtoc file for the drive. Below is a copy of the
file I have for my HP SCSI drive on my 3b2/400.
===================cut here======================

See the command fmthard(1M) for detailed info on creating this file.

Wouldn't it be nice if AT&T did alot of things like the rest of the
world does? <sigh>
