No, that's not what I meant.

'gvinum start' loads the kernel module which in turn searches for 
vinum-GEOMs and loads the configuration data. It doesn't change the 
state of any gvinum item.

Try 'gvinum start <plex-name>' or within gvinum(8):

gvinum> start <plexname>

This (as far as I investigated :-)

a) initializes a newly created RAID5-plex    or

b) recalculates parity informations on a degraded RAID5-plex with
   a new replaced subdisk.

So, a 'gvinum start raid5.p0' initializes my RAID5-plex if newly 
created. You can monitor the initialization process with subsequent 
'gvinum list' commands.

If you degrade a RAID5-plex with 'camcontrol stop <diskname>' (in case 
of SCSI-Disks) and 'repair' it afterwards with 'camcontrol start 
<diskname>', the 'gvinum start raid5.p0' (my volume here is called 
'raid5') command recalculates the parity and revives the subdisk which 
was on disk <diskname>.
