Adding Mirror Chunks to a Dbspace

If you add a chunk to a dbspace that is already mirrored, you must also add a corresponding mirror chunk. You can use the onutil ALTER DBSPACE command to add a primary and a mirror chunk to a dbspace simultaneously, as the following example shows:

% onutil 
1> alter dbspace dbsp1 add chunk 
2> chunk "/dev/chunk2" offset 1024 size 1 gbytes
3> mirror "/dev/mirror2" offset 1024 ;
