I think you want

	filsys main cw0f(w1w1.<0-1>.0)

That is, wT is scsi adaptor 0, target (a.k.a.  unit) T, lun 0; wA.T.L
is adaptor A, target T, lun L. lun is almost always 0 (some jukeboxes
use, or can be configured to use, non-zero luns).  wT.L is adaptor 0,
target T, lun L, which turns out to be rarely useful.  fsconfig(8) has
the whole story.

(You may also have to issue

	filsys dump o

again afterward; I'm not sure.  I always do this after redefining a cw
main since the dump is derived from the worm part of the cw
declaration.)

I believe that this should grow your fake worm, but Charles or Nigel
probably have more experience with this.  I've changed cache disks and
added and removed (as-yet-unwritten) optical disks, and the fs kernel
always seems to automatically and correctly resize the cache or the
worm as appropriate.  On the other hand, I'm not sure how the
fake-worm's bitmap would interact with adding more space.

or shooting yourself in the root. ☺  Obviously a dump to CD of your
own files first wouldn't be a bad idea.  Type carefully on the fs
console and double-check commands before pressing `return'.
