Before ULTRIX V4 supported disks were known by the installation procedure
since some geometry information was desired by the mkfs(8) used to create
the initial root file system. Starting in V4, a new I/O control was added,
DEVGETGEOM, that would allow a program to query a disk for it's geometry.
The installation procedure was modified to use this I/O control to get
the information.
Some disks put their geometry information in the places that the ULTRIX
drivers expect and you can perform an installation using these disks.
Other disks don't put their geometry inforation in the expected place
and the installation fails. The message you're getting is the symtom
of this problem. The solutions are:
1. Once the standalone system is loaded, use the System Management
option and edit the appropriate installation script so that it
doesn't try to ask the disks it's geometry and uses one you give
it instead. The script to modify is install.1.
It's worth noting that if the early part of the installation
doesn't recognize the disk and can't get the geometry the later
part of the installation that creates the /usr (and /var) file
system(s) won't work either.
2. Do enough installation on a supported disk to get a working system
up and then move what file system you want on the other disk to
that disk.
