PROBLEM: (86918) (PATCH ID: OSF445-561)
********
The problem is that addvol allows a HSG/HSZ disk partition to
be added to an 'on-line' (or off-line), existing domain, when
the disk partition can not access all the blocks that the
disklabel indicates, and consequently, all the blocks added
to the domain.  This due to the disklabel no longer being valid.
