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.
