Hi managers,

Thanks to all that responded, especially Thomas Sjolshagen at HP, who was
first to reply...

The answer is to rewrite the disklabel, then mount, as described in the
mount man pages:

disklabel -rw dskN
mount -u -o extend file_dmn#file_set /mnt_point

The partition that is being expanded must be one that extends to the
whole of the disk, ie c or h, and its wise not to have too much activity
on the disk whilst its being extened.

What is sadly missing from the man page is the minor point that you must
have an ADVFS Utilities license in order to use the -o extend option.

Cheers,

Rob
