NCR Unix 3.02 MP-RAS - disk layout
Semi-short answer:
You need to reinstall. The disk partition in which your MP-RAS image
resides in, is too small to add any -additional- filesystems and there
are no tools to dynamically grow your VxFS filesystems. Moreover,
the version of MP-RAS you're using doesn't "see" other disk partitions
on the -same- disk (so you can't just create other disk partitions on
the 35G disk and add new filesystems there). If you can't re-install
for some reason (lost CD or license diskettes), you can add a new
drive to the system and MP-RAS will recognized the new drive (once
you reboot (or run ``mktable''), then use ``sysadm'' to create new
filesystems.

Comments:
I'm not aware of any NCR (or Teradata) sponsored installation that
would appear this way. If I were to guess, the 2G drive(s) died and
the next smallest drives available were 35G so those were used.
Notably, you're missing ``/var'', ``/opt'', and ``/usr'' which are fairly
standard on all NCR UNIX (MP-RAS) installations.

The following message is particularly broken (but fixed in much later
versions of MP-RAS) and output by the ``dfspace'' command:

...
Total Disk Space: 84.45 MB of 912.39 MB available ( 9.26%).

MP-RAS (until recently) assumed it owned the entire disk whenever
it was installed, and to that end, was installed in so-called "no-compat"
mode. Thus, it only "knows" about the drive to the extent of the disk
partition it which it resides (was installed) in.

installboot

installboot(1M) 														   installboot(1M)

NAME

       installboot - install bootblocks in a disk partition

SYNOPSIS

       installboot bootblk raw-disk-device

       The boot(1M) program, ufsboot, is loaded from disk by the bootblock program which resides in the boot area of a disk partition.

       The  ufs  boot objects are platform-dependent, and reside in the /usr/platform/platform-name/lib/fs/ufs directory. The platform name can be
       found using the -i option of uname(1).

       The installboot utility is a SPARC only program. It is not supported on the  architecture.  users should use installgrub(1M) instead.

       bootblk	       The name of the bootblock code.

       raw-disk-device The name of the disk device onto which the bootblock code is to be installed; it must be a character device which is  read-
		       able and writable. Naming conventions for a SCSI or IPI drive are c?t?d?s? and c?d?s? for an IDE drive.

       Example 1: Installing UFS Boot Block

       To install a ufs boot block on slice 0 of target 0 on controller 1 of the platform where the command is being run, use:

	      example# installboot /usr/platform/`uname -i`/lib/fs/ufs/bootblk 
		   /dev/rdsk/c1t0d0s0

       /usr/platform/platform-name/lib/fs/ufs

	   directory where ufs boot objects reside.

       /platform/platform-name/ufsboot

	   second level program to boot from a disk or CD

WARNINGS

       The installboot utility fails if the bootblk or openfirmware files do not exist or if the raw disk device is not a character device.
