Re: dropping initial chunk

You can, however, not by dropping the initial chunk of the dbspace but by dropping the dbspace itself: So you cannot: onspaces -d dbspacename -p /usr/informix/disks/chunk10 -yif chunk10 is the first chunk of a dbspace but you can: onspaces -d dbspacename -yand drop the entire dbspace including the first chunk and if that is the only chunk these are equivalent.
