Only had one respondent (thanks to Jeff Stuesse
<jds@enterpriseconsulting.com>)
who pointed me in the right direction.
1. The command "vxdg list <disk group>" lists which
disks have enabled configuration databases on them.
2. Neither Sun nor Veritas have told me how I can
specify where the databases should be enabled, but
using "vxdisk set nconfig=all <disk group>" will put
a copy on all disks in the group, and overcome the
rendundancy issue i had.
